Genius Navigator 380, mouse and VOIP phone in one

 It only move that cursor around your screen?! Not anymore. With the Genius Navigator 380, your mouse now works as a VOIP phone, an instant messaging device, not to mention the 1200dpi optical mouse part. All of these are rolled into its sweet clamshell design. Of course, if you have this multi-functional device, its primary use will be the mouse, but when you receive a call from one of your friends, it will either ring or flash a green light (underneath where your hand would be).


The Genius Navigator 380 is a great little peripheral for you business travelers as well. You can save precious room in your laptop case to use for that enormous power adapter they didn’t tell you the laptop required. To top it off, the Genius Navigator 380 can juggle six separate instant messengers (Skype, MSN, Yahoo, GoogleTalk, QQ, and AIM) simultaneously in one window. Another multi-function that will save you space and money.

Genius Navigator 380 can be carried along with a notebook and features a 1,200 dpi optical engine. The LED on the mouse blinks when there is a call through the IMs. And if the PC speaker is on, the ringing will also alert an incoming phone call. The mouse opens like a clamshell mobile phone. The Genius Navigator 380 is available in India for Rs.1,850 (INR).

Top Smartphone

Smartphones offer greater functionality than regular cell phones, with the ability to access the Internet, download email, work with document attachments, sync data with personal and corporate computers, send instant messages, play music, show streaming video and scout out locations with GPS - in addition to making phone calls.

Now lets check the top 10 smartphone in market.


1. T-Mobile myTouch 3G Slide

An Android smartphone for first-time users

pros
  • Superb QWERTY keyboard
  • Easy-to-use interface
  • Good call quality
cons
  • Clunky slider mechanism
  • Sub-par camera
  • Weak battery
  
Review:
The T-Mobile MyTouch 3G Slide is an entry-level Android device geared for first-time smartphone users. Reviewers praise its midrange feature set, top-notch QWERTY keyboard and exceptional ease of use. Chris Ziegler at Engadget.com considers it "among the best" QWERTY Android sliders, and CNET's Bonnie Cha says T-Mobile's customized user interface "brings a more consumer-friendly look and feel" to Android. However, experts also say the Slide's features can't compete with powerhouses like the HTC Droid Incredible (Free with contract) or HTC EVO 4G (*Est. $190 with contract). Nevertheless, for those transitioning to smartphones, the MyTouch 3G Slide may be a sound choice.
Thanks to a hardware redesign and a software makeover, the MyTouch 3G Slide is "more than just a re-warmed" MyTouch 3G, says Lisa Gade at MobileTechReview.com. The Slide has a larger 3.4-inch touch-screen display with pinch-to-zoom support, a new QWERTY keyboard and bigger 600 MHz processor. Critics praise the bright, responsive screen, and Kenneth Butler at Laptop Magazine says the QWERTY keyboard "hits the sweet spot." Cha likes its spaciousness, but says the slider can be clunky to open.
The Slide runs on Android OS 2.1 (Eclair) with two user interfaces: one from HTC and the other from T-Mobile, which users say is more user-friendly. In addition to a guided set-up process, the Slide has Android's multi-panel home screen, Google apps and MS Exchange support. The HTC Sense interface adds five customizable home screens and apps like Friendstream, which combines Facebook, Twitter and Flickr updates. The T-Mobile interface features My Modes, which lets you personalize the home screen for work or home, the Faves Gallery (which keeps track of your 20 favorite people), and the Genius button for voice-recognition searching and messaging, a barcode reader and an bundle of recommended apps.
Focus on messaging
For the most part, the enhancements impress reviewers. MobileTechReview.com's Gade says "it's a pleasure to see a midrange phone get the current goods," while PCMag.com's Sascha Segan likes how it focuses on messaging. But Laptop Magazine's Butler says the Motorola Cliq (Free with new contract) does "a better job of integrating social networking."
The Slide is also a good multimedia phone, according to Segan. It includes a standard Android music player, free DoubleTwist syncing software, a 3.5 mm headphone jack and a YouTube video player. While the 5-megapixel camera gets lukewarm reviews for sub-par image quality, the Slide's browser "notched decent page load times," says Butler. Reviewers report excellent call quality with clear volume and reliable 3G coverage, but battery life -- the most common complaint among users at CNET -- falls short of its rated 7.5 hours in tests at CNET, Laptop Magazine and PCMag.
Laptop Magazine's review provides the most complete comparison to rival smartphones such as the Google Nexus One and HTC Evo 4G. Other professional review sources, including MobileTechReview.com and PCMag.com, make fewer comparisons with rival smartphones but nevertheless deliver thorough evaluations, while user reviews at CNET help to illustrate some of the Slide's drawbacks.


2.  T-Mobile Garminfone


An Android smartphone with excellent Garmin GPS

pros
  • Outstanding navigation
  • Navigates even in dead zones
  • Easy user interface
  • Includes dash mount/charger
cons
  • Older version of Android
  • Runs slowly at times
  • Blurry photos and video in some tests
  • May be too basic for advanced users
A phone that combines great Garmin navigation with a smartphone that's at least passable is bound to be a sought-after option. The Android-based T-Mobile Garminfone has its flaws as a smartphone, testers say, but if you want the best possible phone navigation, this is it -- and it's far better than Garmin's last attempt, the widely panned Garmin nuvifone G60 (Free with contract).
Navigation is "fantastic" with the Garminfone, says Tim Stevens at Engadget.com, and other testers agree. While other Android phones such as the Motorola Droid (Free with a new contract) include free turn-by-turn Google Maps Navigation, testers say the Garminfone is a better, more full-featured navigator -- especially since it can navigate regardless of dead zones, unlike the Google Maps version, which must be connected via cell signal to work. The Garminfone comes loaded with North American maps and 6 million points of interest. In a test at Laptop Magazine, it gets a stronger GPS signal than the Droid and is "pretty much identical to a dedicated in-car unit," reviewer Mark Spoonauer says.
Directions in your own voice
The Garminfone speaks directions loudly, its 3.5-inch touch screen is easy to see, and testers appreciate the free dash mount/charger that comes in the box. Free traffic reports, weather information, gas prices and movie times are also included. Reviews say the Garminfone has a couple of neat extra features to play with, too. Garmin Voice Studio allows you to record directions in your own voice. And if a friend sends you a text message with an address in it, you can navigate directly there. The Garminfone even remembers where you parked. "This is brilliant stuff," says Jamie Lendino at PCMag.com.
As for handling calls while navigating, reviews say the Garminfone does a smooth job. When you hit the answer button, the Garminfone switches to speakerphone and mutes its navigation prompts while you're talking, although the screen keeps navigating. Everything switches back to normal once you hang up. Call quality is fine in Laptop Magazine's test, although PCMag.com's Lendino says that while callers sounded clear, they "complained that I sounded a little thin and distant."
Smartphone a bit poky and outdated
Smartphone features are where the Garminfone falters in reviews. It's not as powerful as other Android smartphones, such as the Motorola Droid X. With just 256 MB of RAM, "some operations felt sluggish" in PCMag's test. The Garminfone has 4 GB of memory, expandable via microSD card. It runs the older Android 1.6, not the current version, which means it can't run some of the latest Android apps. On the plus side, testers say the Garminfone's simplified interface makes it easy to use, although advanced users will miss some of the usual Android customizations; Engadget.com's Stevens says this is "not a phone for power users." The touch-screen keyboard with haptic feedback works fine in tests.
Lackluster camera
Web pages load quickly over T-Mobile's 3G network in Laptop Magazine's test -- four seconds for NYTimes.com, five seconds for CNN.com, six seconds for ESPN.com -- although sites without mobile versions take longer. Video and photos range from "decent" to "blurry," with a 3-megapixel camera that lacks a flash that Spoonauer calls "far from the cutting edge." PCMag.coms Jamie Lendino neatly sums up reviewer sentiment: "The Garminfone is the nation's best navigation phone, but there are better choices for a general-purpose smartphone."
Reviews of the Garminfone at Laptop Magazine, PCMag.com and Engadget.com are exceptionally thorough, giving the reader an excellent idea of how the phone performs and how it stacks up against the competition. A video review at CNET expertly critiques the phone and shows it in action.


3.  Motorola Droid 2

Droid 2 incorporates much-needed updates, but offers few new features

pros
  • Android 2.2 improves web browsing
  • Easy, responsive navigation
  • 3G mobile hotspot for up to five devices
  • Improved slide-out keyboard
  • 5-megapixel camera
cons
  • Stiff keyboard buttons
  • Mobile hotspot costs extra
 While it certainly raises the bar for performance and features compared to the original Droid (Free with new contract), the Motorola Droid 2 for Verizon "takes only baby steps forward from the original, struggling to keep up with new titans like the Droid X," says Stewart Wolpin of DigitalTrends.com. What sets the Droid 2 apart is the addition of Android's 2.2 Froyo software, which adds support for Adobe Flash and 3G mobile hotspot capabilities for up to five devices. Hotspot capability will cost you an additional $20 per month for 2 GB of data. Internal changes include an upgrade from a 550 MHz processor to a 1 GHz processor, 512 MB of memory and better battery life (almost 10 hours of talk time, according to PCMag.com tests).
The Android 2.2 "perfectly replicates the desktop experience," PhoneArena.com editors say, thanks to support for the Adobe Flash player. (Most Android smartphones will get this update automatically.) Reviewers praise the Droid 2's toned-down Motoblur interface. PCMag's Sascha Segan says that it's "much less intrusive than Samsung's or HTC's" and will appeal to those looking for a "sparer Android interface." PhoneArena.com calls the Droid 2's screen "nothing that exciting" since the display hasn't changed from the original, but editors are pleased with its responsiveness. Segan rates performance "somewhat faster" than the HTC Droid Incredible (*Est. $80 with new/renewal contract) but "probably be a little slower" than the Samsung Fascinate, another Verizon Android phone.
Responding to complaints about the original Droid, the Droid 2 features a redesigned slide-out QWERTY keyboard that sheds the troublesome D-pad and incorporates bigger, raised keys. It's a bit of a letdown, however, as the keyboard is still "tight" compared to phones such as the Samsung Epic 4G, says PCMag's Sascha Segan, and it still has the "same stiff feeling keys," according to editors at PhoneArena.com. The Droid 2 retains the original Droid's 5-megapixel camera, 720-by-480-pixel video resolution and 3.7-inch TFT capacitive touch screen (854 pixels by 480 pixels). Segan notes that the camera "overexposes shots," though they're still sharp, and finds that the improved 30 frames-per-second video recording (up from 24 fps on the original) presents "smooth and sharp" videos. CNET's Bonnie Cha agrees that pictures are "bright," but feels video quality is "very hazy" even at the highest resolution.


4. Motorola Droid X

Verizon's Droid X leads the Android pack, but may be too big for some

pros
  • Huge 4.3-inch display
  • Roomy virtual keyboard
  • Speedy 1 GHz processor
  • Excellent noise-canceling microphones
  • Long battery life
cons
  • Too big for small hands
  • No front-facing camera for video calling
  • Sluggish Motoblur interface
Everything about the Motorola Droid X is big: its 5-inch chassis, 4.3-inch display, roomy virtual keyboard, fast 1GHz processor and long battery life. "It's a beast, but in a good way," says CNET's Bonnie Cha, while Lisa Gade at MobileTechReview.com calls it "lustworthy." Other reviewers are equally smitten. At PCMag.com, the Droid X snatches the best smartphone crown from the HTC Droid Incredible, while Engadget.com's Chris Ziegler says it "steals the spotlight" from Verizon's other smartphones (such as the Incredible). But David Pogue at The New York Times puts the Droid X's "best" title in perspective: "In this business, the state of the art changes as often as Lady Gaga changes outfits," he says, pointing out that several phones have been proclaimed the "best" Android phone in the past year.
The Droid X is slightly taller than the HTC Evo 4 (*Est. $190 with contract), Sprint's flagship Android phone, but it's a tad lighter thinner. "You feel as if you're talking into a frozen waffle," says Pogue, while Ziegler says it's "definitely not for the small of hands." The huge 4.3-inch touch-screen display appears "truly cinematic," says Gade. It packs a higher resolution and a wider aspect ratio than the Evo (16:9 vs. 5:3), says Ziegler, but experts say the Super AMOLED display on the new Samsung Galaxy S, another Android phone due out this fall, may be tough to beat. The Droid X's spacious virtual QWERTY keyboard has optional Swype technology, which lets you type by sliding from key to key, rather than typing. Critics say it's fast and accurate -- albeit a reach for small hands. Most reviewers say that the Droid X is a great choice for most, but note that users with small hands may prefer the slimmer Droid Incredible (*Est. $150 with new contract).

5.  HTC EVO 4G

4G Android smartphone hits a few speed bumps

pros
  • Huge 4.3-inch display
  • First 4G network device
  • Fast downloads and media streaming
  • Doubles as a personal Wi-Fi hotspot
cons
  • Bulky
  • Limited 4G coverage
  • Extra monthly fees
  • Convoluted video chat app
  • Paltry battery life
The HTC EVO 4G "offers a big, beautiful, and powerful window" to the online world, says Sascha Segan at PCMag.com. As the first 4G (fourth generation) network device in the U.S., the EVO raises the bar with "much faster" web pages, e-mail and skip-free Internet video, says David Pogue at The New York Times. It also touts massive specs: a 4.3-inch display (larger than the iPhone's), hotspot abilities, speech recognition, Flash Lite, dual cameras, video calling, HD video and an HDMI port. Most reviewers regard the EVO as the most powerful Android smartphone, putting it in the pantheon with the HTC Incredible (*Est. $150 with contract) and Apple iPhone 4 (From $200 with contract). Still, the EVO isn't flawless, and Pogue says the "groundbreaking features come with enough fine print to give the White Pages an inferiority complex."
Sprint brands the HTC EVO as the "first" 4G device, even though only 32 metro areas have such coverage and the smartphone switches over to 3G otherwise. The phone uses WiMAX technology to access 4G, but it's solely for data downloads and not phone calls, and WiMAX technology fizzles in urban landscapes. Chris Ziegler at Engadget.com says "we found ourselves getting four bars of 4G walking down the street, then ducking into a coffee shop and dropping to just one or even no bars at all." Sprint also charges EVO owners an additional $10 a month for WiMAX. CNET's Bonnie Cha considers the extra fee reasonable, but says that "making it mandatory for everyone, regardless of whether you live in a 4G market or not, seems unfair."

6.  Apple iPhone 4

Apple iPhone 4 leads the smartphone pack, but not by much

pros
  • Brilliant high-contrast display 
  • Powerful 5-megapixel camera
  • Unrivaled app store
  • Easy FaceTime video calling
cons
  • Limited multitasking
  • Unreliable reception
  • FaceTime restricted to iPhone 4 owners
Reviewers agree the iPhone 4 is the best yet, with huge upgrades to the iPhone 3GS (*Est. $100 with contract). Though its prowess remains undisputed, few critics are willing to peg it the absolute best out there, however. "The iPhone 4 deserves its place in the pantheon of cellphone gods, but as part of a distinguished group, not as a single overlord," says Sascha Segan at PCMag.com. With a level playing field, many critics feel that choosing the right smartphone boils down to a matter of personal preference. "iPhone is no longer the only worthy contender," says David Pogue of The New York Times. The iPhone 4 is available in 16 GB (*Est. $200) and 32 GB (*Est. $300) configurations. 
The buzzworthy feature this time around is FaceTime video calling, which allows you to make face-to-face calls using the VGA camera on the front of the iPhone 4 or the 5-megapixel shooter on back. The technology isn't new, but experts say Apple gets it right. "It's the first phone to make good video calls reliably, with no sign-up or set up, with a single tap," Pogue says, while other critics report it's easier than Android's Fring or Qik apps. However, FaceTime works only on Wi-Fi, and both callers must have an iPhone 4. "That makes FaceTime a special-occasion parlor trick rather than a general purpose solution," says Segan.

Mobile TV

Mobile TV is the latest technology where the TV services are streamed on to the mobile or hand-held devices. Mobile TV is going to get more and more prevalent over the next couple years . There is lot of momentum in the area, even if there are a few commercial products so far.
Already, many mobile operators offer a selection of television channels or individual shows, which are streamed across their third-generation (3G) networks. In South Korea, television is also sent to mobile phones via satellite and terrestrial broadcast networks, which is far more efficient than sending video across mobile networks; similar broadcasts will begin in Japan soon. In Europe, the Italian arm of 3, a mobile operator, recently acquired Canale 7, a television channel, with a view to launching mobile- TV broadcasts in Italy in the second half of 2006. Similar mobile- TV networks will also be built in Finland and America, and are being tested in many other countries.
At the moment, mobile TV is mostly streamed over 3G networks. But sending an individual data stream to each viewer is inefficient and will be unsustainable in the long run if mobile TV takes off. So the general consensus is that 3G streaming is a prelude to the construction of dedicated mobile- TV broadcast networks, which transmit digital TV signals on entirely different frequencies to those used for voice and data. There are three main standards: DVB-H (Digital Video Broadcasting - Handhelds) , favoured in Europe; DMB (Digital Multimedia Broadcasting), which has been adopted in South Korea and Japan; and Media FLO , which is being rolled out in America. Watching TV using any of these technologies requires a TV -capable handset, of course. Among the three technologies, DVB-H was officially adopted by ETSI (the European Telecommunications Standards Institute) as the standard for mobile TV services in Europe.
Just as there are several competing mobile- TV technologies, there are also many possible business models. Mobile operators might choose to build their own mobile- TV broadcast networks; or they could form a consortium and build a shared network; or existing broadcasters could build such networks. Some channels will be given away for free, while others are for paying subscribers only. The outcome will vary from country to country, depending on the regulatory environment and the availability of spectrum. In Italy, 3 bought Canale 7 to get its hands on its spectrum and its broadcaster's licence; in Britain, Finland and America, the scarcity of spectrum makes shared networks most likely.
Among the various mobile TV technologies, the likeliest near-term solution will be to unify under the ETSI-endorsed DVB-H standard. It is considered to be is the best delivery system currently available for most markets, according to many of the operators and vendors.
DVB-H:
DVB-H is a terrestial digital TV standard that uses less power in receiving client than DVB-T (DVB Terrestial), and allows the receiving device to move freely while receiving the transmission, thus making it ideal for mobile phones and haldheld computers to receive digital TV broadcasting over the digiTV network (without using mobile phone networks at all) .
The basic DVB-T television standard has been modified to enable the receivers to be less power hungry, as DVB-T is used in an environment where power consumption is not a major consideration. This power reduction has been achieved by time slicing so that the receiver is only switched on in those time intervals when viewing the channel of interest. These intervals could be anything between a few milliseconds and a few seconds. It therefore reduces power consumption by being switched off for the rest of the time when non-required data is being transmitted. There is therefore a trade off between the data rate required for the service and how much this can be packed into short bursts to save the battery power of the receiver.
Like DMB, DVB-H uses COFDM but with a bandwidth of either 6, 7, or 8 MHz. Additionally it uses a range of different types of modulation from QPSK up to 64QAM and this enables it to have a very high data rate. However it is more susceptible to signal variations and synchronisation problems. Additionally higher transmitter powers are required than those needed for DMB. Also frequencies that are likely to be used have not yet been allocated but it is thought they might be within the existing television bands. The wide RF bandwidth also means that current drain is increased, as wide bandwidth amplifiers are inherently more power hungry.
As it is really just an extension to DVB-T, DVB-H uses the same specs DVB-T. Video is normally encoded with MPEG-2 (but can be encoded with MPEG-1 as well, although very rarely used) and the standard, just like its other siblings DVB-C (Cable) , DVB-S (Satellite) and DVB-T, is mostly used in Europe.
Benefits of DVB-H:
  • An approved standard for handheld equipment by ETSI (European Telecommunications Institute) with a high adoption rate worldwide
  • DVB-H is an open industry standard that was developed by the DVB Project , an industry consortium and is currently being supported by leading companies throughout the wireless industry.
  • It benefits from existing DVB-T infrastructure components, which reduces initial investments in many cases
  • It provides the best user experience in the mobile environment, with an energy saving handset that is only ‘on’ 10% of the time, programme guide, soft handover and in-building coverage
  • It offers an excellent, broadcast-quality picture, because the screen resolution is of a similar standard to VHS
  • Battery consumption is reduced by 90% due to time-slicing technology
  • DVB-H comes from the proven DVB standard used in Europe for standard DTV transmission with a low power mode for battery-powered devices.
  • Efficient use of bandwidth enables up to 55 mobile channels plus scalability
  • It is supported by publicly available air interface specifications helping to drive device interoperability and market development
  • Its security includes end-to-end control of stream encryption, generation of decryption keys and delivery of keys to consumers in a billing-integrated way
  • It will be accessible by an estimated audience of approximately 300 million mobile users by 2006

4G or Fourth Generation Networks

4G or Fourth Generation is future technology for mobile and wireless comunications. It will be the successor for the 3Rd Generation (3G) network technology. Currently 3G networks are under deployement. Approximatly 4G deployments are expected to be seen around 2010 to 2015.
The basic voice was the driver for second-generation mobile and has been a considerable success. Currently , video and TV services are driving forward third generation (3G) deployment. And in the future, low cost, high speed data will drive forward the fourth generation (4G) as short-range communication emerges. Service and application ubiquity, with a high degree of personalization and synchronization between various user appliances, will be another driver. At the same time, it is probable that the radio access network will evolve from a centralized architecture to a distributed one.
The evolution from 3G to 4G will be driven by services that offer better quality (e.g. multimedia, video and sound) thanks to greater bandwidth, more sophistication in the association of a large quantity of information, and improved personalization. Convergence with other network (enterprise, fixed) services will come about through the high session data rate. It will require an always-on connection and a revenue model based on a fixed monthly fee. The impact on network capacity is expected to be significant. Machine-to-machine transmission will involve two basic equipment types: sensors (which measure parameters) and tags (which are generally read/write equipment).
It is expected that users will require high data rates, similar to those on fixed networks, for data and streaming applications. Mobile terminal usage (laptops, Personal digital assistants, handhelds) is expected to grow rapidly as they become more user friendly. Fluid high quality video and network reactivity are important user requirements. Key infrastructure design requirements include: fast response, high session rate, high capacity, low user charges, rapid return on investment for operators, investment that is in line with the growth in demand, and simple autonomous terminals. The infrastructure will be much more distributed than in current deployments, facilitating the introduction of a new source of local traffic: machine-to-machine.

Key 4G technologies:
  • Orthogonal Frequency Division Multiplexing (OFDM)
  • Software Defined Radio (SDR)
  • Multiple-input multiple-output ( MIMO )

Initially DoCoMo planned to introduce 4G services around 2010. Recently DoCoMo announced plans to introduce 4G services from 2006, i.e. four years earlier than previously planned. NTT DoCoMo, Inc. announced that high-speed packet transmission with 1 Gbps data rate in the downlink was achieved successfully in a laboratory experiment using fourth-generation (4G) mobile communication radio access equipments.

The key enablers for the 4G are:
  • Sufficient spectrum, with associated sharing mechanisms.
  • Coverage with two technologies: parent (2G, 3G, WiMAX) for real-time delivery, and discontinuous pico cell for high data rate delivery.
  • Caching technology in the network and terminals.
  • OFDM and MIMO.
  • IP mobility.
  • Multi-technology distributed architecture.
  • Fixed-mobile convergence (for indoor service).
  • Network selection mechanisms.

Internet Protocol Version 6

Internet Protocol Version 6 (IPv6) is a new suite of standard protocols for the network layer of the Internet defined by IETF to replace the current version of Internet Protocol version 4 (IPv4). IPv6 is also called as Next Generation Internet Protocol or IPng.
IPv6 is designed to be an evolutionary step from IPv4. It is a natural increment to IPv4. It can be installed as a normal software upgrade in internet devices and is interoperable with the current IPv4. Its deployment strategy is designed to not have any flag days or other dependencies. IPv6 is designed to run well on high performance networks (e.g. Gigabit Ethernet, OC-12, ATM, etc.) and at the same time still be efficient for low bandwidth networks (e.g. wireless). In addition, it provides a platform for new internet functionality that will be required in the near future.
IPv6 describes rules for three types of addressing: unicast (one host to one other host), anycast (one host to the nearest of multiple hosts), and multicast (one host to multiple hosts). Additional advantages of IPv6 are:
  • Options are specified in an extension to the header that is examined only at the destination, thus speeding up overall network performance.
  • The introduction of an "anycast" address provides the possibility of sending a message to the nearest of several possible gateway hosts with the idea that any one of them can manage the forwarding of the packet to others. Anycast messages can be used to update routing tables along the line.
  • Packets can be identified as belonging to a particular "flow" so that packets that are part of a multimedia presentation that needs to arrive in "real time" can be provided a higher quality-of-service relative to other customers.
  • The IPv6 header now includes extensions that allow a packet to specify a mechanism for authenticating its origin, for ensuring data integrity, and for ensuring privacy.

IPv6 Features:
  • New header format
  • Large address space
  • Efficient and hierarchical addressing and faster routing infrastructure
  • Stateless and stateful address configuration
  • Mobile support (Mobile IPv6)
  • Built-in network layer security
  • Better support for QoS
  • New protocol for neighboring node interaction
  • Extensibility

Addressing Format :
An IPv4 address is a 32-bit value that's usually written in "dotted quad" representation, where each "quad" represents a byte value between 0 and 255, for example:
127.0.0.1
This allows a theoretical number of 2^32 or ~4 billion hosts to be connected on the Internet. Due to grouping, not all addresses are available today.
IPv6 addresses use 128-bit technology, which results in 2^128 theoretically addressable hosts. This allows a really big number of machines to be addressed, and it will fit all today's requirements plus PDAs, cell phones, and even IP phones in the near future without any sweat. When writing IPv6 addresses, they are usually divided into groups of 16 bits written as four hex digits, and the groups are separated by colons. An example is:
fe80::2a0:d2ff:fea5:e9f5
This shows a special thing -- a number of consecutive zeros can be abbreviated by a single "::" once in the v6 number. The above address is thus equivalent to fe80:0:00:000:2a0:d2ff:fea5:e9f5 -- leading zeros within groups can be omitted.

Mobile IPv6:
Mobile IPv6 allows an IPv6 node to be mobile - to arbitrarily change its location on an IPv6 network - and still maintain existing connections. When an IPv6 node changes its location, it might also change its link. When an IPv6 node changes its link, its IPv6 address might also change in order to maintain connectivity. There are mechanisms to allow for the change in addresses when moving to a different link, such as stateful and stateless address autoconfiguration for IPv6. However, when the address changes, the existing connections of the mobile node that are using the address assigned from the previously connected link cannot be maintained and are ungracefully terminated. The key benefit of Mobile IPv6 is that even though the mobile node changes locations and addresses, the existing connections through which the mobile node is communicating are maintained.

The new devices bring out a refreshed Nokia in this scene, but can these really compete against the smartphones thrown out by the likes of Apple, HTC, and Samsung? We've yet to count in on the Japanese brands who are just about to rise from their domestic market and who are facing pressure to grow into international markets, most especially in the smartphone arena. The latter isn't going to be making their move in just a few months time, that's for sure - not until they've figured out their perfect products to combat against the iPhone, and until then, we'll have to sit back and see how the market reacts to these new phone lines when they finally make their retail debut.

OLEDs are supposed to be the super displays that will drive LCDs into the abyss of obscurity... once perfected that is. But as it is, AMOLED makers have been struggling in getting their products to withstand the harsh sunlight and retain whatever vivid image they can display without having to sacrifice power savings. Greek-based Techblog TV ran Samsung Galaxy S on a 4-inch 480 x 800 Super AMOLED display, against an HTC Desire on a 3.7-inch 480 x 800 AMOLED display, against a Sony Ericsson XPERIA X10 on a 4-inch 480 x 854 TFT LCD and checked out how they fared against Helios' blinding rays. Vids after the break!

iPhone destroyed by 'Death Ray'


iPhone destroyed by 'Death Ray'

What do you do when you have an outdated / older edition iPhone, a 65" Fresnel lens, and apparently nothing else better to do in your free time? Why, toast your iPhone, of course.

There are some people out there who take their iPhones seriously. They get EVERY EDITION of the iPhone that comes out, in the same way your local comic book guy might avail of every single cover design X-Men #1. Every purchase of a new iPhone makes the previous one obsolete, ensuring that their owners dispose of them in a variety of ways.

One way apparently, is by death ray. Using a 65 inch Fresnel lens, some batteries, and a large backyard, one consumer proves that old iPhones can still sizzle - literally.


HTC Desire Google Android Touchscreen Smartphone


The HTC Desire - A Google Android Touchscreen Smartphone

The battle is on! With the release of the HTC Desire, Samsung Galaxy S, Motorola Droid X, and Sony Xperia X10, the battle at the high-end segment for the Android OS has officially begun. We are sure that many are wondering which among these heavyweights is worth their hard-earned money, and we help to try and address that question with a review of the HTC Desire today.


The HTC Desire - A Google Android Touchscreen Smartphone

Design: Strikingly HTC


We won't mince words here and will say it outright: the HTC Desire is one beautifully crafted device. It looks strikingly similar to its cousin, the Nexus One, and it mainly shares the same design sensibilities, which was first seen in the HTC Hero. This is evident from the mixture of materials, the slightly protruding lip, as well as the button cluster. From the soft touch material on the rear that extends to the front lip to the aluminum frame around the screen, the Desire reeks of quality construction and premium materials. It feels nice and sturdy in the hands, and has a reassuring weight that should prove to be highly pocketable for many.

In lieu of the traditional trackball found older HTC Android devices, the Desire touts a clickable optical trackball that tracks finger movements, similar to the Legend. We found this to be an acceptable replacement, quite useful for navigating around text. Thankfully the Home, Menu, Back, and Search keys are physical keys, making them easy to find and reliably responsive, unlike their touch counterparts. Other buttons include the top Power button and the volume slider found on the left side.

The camera module does protrude a bit from the rear, making us quite certain that it will suffer a good number of nicks over time. Beside it to the right, the LED flash and speaker module can be found. At the bottom, the micro USB port for data and charging can be found (thank God for this!), while on the top, beside the Power button, the 3.5mm jack is conveniently placed.


The HTC Desire - A Google Android Touchscreen Smartphone

Highlights: Fit For A Flagship


Given its place in the pecking order of HTC's device hierarchy, the Desire is rightfully packed to the brim with the best parts that the HTC factory has on offer. First and foremost among these is the 3.7-inch 800 x 480 capacitive AMOLED display (the EVO 4G and HD2 pack TFT LCDs). Next in line is the 1GHz Snapdragon processor and 576MB of RAM, both the fastest and largest capacity that HTC has on offer on their smartphones, respectively. It also packs a bevy of high-end radios from HSDPA, Bluetooth, and WiFi.

Multimedia-wise, the 5 megapixel camera that will be given the capability to record 720p videos with the Froyo update provides the brunt of the Desire's imaging muscle, which is complemented by an LED flash. A 3.5mm jack comes in as a standard, ensuring users are able to use their headphones of choice.

All these are run under Android 2.1 or Eclair, something that HTC promises will be upgraded to the latest Android version of Froyo or Android 2.2. And, as expected of any HTC device, the Desire runs on their proprietary Sense UI, which is something that many will be familiar with at this point in time. The version that ships with the Desire is an updated one though, with the most notable additions being the addition of Leap View, which essentially shows a snapshot of each of the seven homescreens when you pinch on a homescreen, as well as the new application called Friend Stream, an app that integrates both Twitter and Facebook accounts in one full featured viewer and widget. On the overall, it is the very presence of the Sense UI that makes the Desire ultimately better than its Nexus One cousin.


The HTC Desire - A Google Android Touchscreen Smartphone

Usability: Seamless And Smooth


As the Android platform, Sense UI, and HTC have already gotten over two years of getting to know each other and feeling each other out, the Desire presents the most user-friendly iteration of Google's operating system yet. This can ultimately be seen in the fact that the device doesn't even ship with a proper manual, with the only on-screen tutorial presented on setup being the one for using the keypad. Again, with Sense UI and Android combined, customization is king, with the user presented a myriad of option on how to personalize their device, all this in the most intuitive manner possible. It may not reach the idiot-friendliness of the iPhone, but it does come pretty close.

One handed operation will be possible for those with bigger hands, but most will find themselves using the Desire with both hands just to make sure they don't drop it. This is not to say that it is large in size, it in fact fits comfortably even in the tight pocket of a pair of jeans. Thankfully, the front cluster buttons are physical ones, though some may find themselves brushing against the optical trackball once in a while due to its close proximity to the buttons flanking it. The touchscreen is extremely responsive and makes for a great user experience, especially when quickly typing out messages.


The HTC Desire - A Google Android Touchscreen Smartphone

Performance: Positive Impressions


On the overall, the Desire is generally snappy, providing users with a smooth and fluid user experience, with very slight hiccups only under heavy network duress. Applications open almost instantaneously, and multi-tasking is largely an enjoyable experience. At this point, HTC seems to be exceedingly familiar with Android, implementing the operating system flawlessly on the hardware and the platform that they provide. We normally would find something to gripe about when it comes to processing muscle and device responsiveness, but in this case, we are left with nothing to say except that the 1GHz Snapdragon CPU combined with the 576MB of RAM on the Desire does indeed get the job done.

Multimedia is also one of the Desire's strong suits, with a crisp and vibrant screen to go along with clean and detailed sound. This makes watching movies and listening to audio a much more reasonable proposition. Browsing the Internet is a breeze on the stock browser, with text reflowing and pinch to zoom coming in extremely handy while navigating pages. The five megapixel camera is pretty fast and of good quality, though it does take some getting used to, especially since the optical trackball is utilized as the shutter button. Touch focusing and a slew of other settings are also adjustable via a revamped camera application. Unfortunately, DivX and XviD aren't supported out of the box, though it is purported to be included in one of HTC's upcoming updates.


The HTC Desire - A Google Android Touchscreen Smartphone

Cost: On Markups And Software Updates


It's a shame that HTC prices their handsets at about PhP 5,000 more than their overseas counterparts. This is the one sure thing that you can count on whenever HTC is to release a model locally, much like the local Canon and Sony subsidiaries. Obviously, the PhP 5,000 premium nets you a local warranty, instant gratification, and less hassle and trouble in actually sourcing the unit. Yet, despite this seemingly high price, it's asking price of PhP 34,990 is still within striking distance of its main competitors' local price tags, still making it a pretty compelling offer.

In the end, its relative value will really actually depend on how extensive and how sustained HTC's efforts will remain in updating the phone's software as the Andorid OS moves along it's development cycle. This is because, by and large, the Desire already has one of the best specced hardware in the market (save perhaps for an HDMI port and higher megapixel count sensor), and is pretty much future proof for the next year and half. If HTC can ensure that the Desire keeps up with Android (and they have promised a Froyo update), then you can rest assured that you have got your money's worth, and the premium of paying for that warranty will be well worth it.

HyperGear Award

Overall: 9.0

The Desire sits atop HTC’s Android hierarchy and rightfully so. They have the best blend of hardware and software in the business, and the Desire clearly epitomizes this.

Design: 9.0

HTC still hasn’t lost its touch as far as materials and construction is concerned. Everything is well put together and feels like a premium device when held.

Highlights: 9.0

There is very little left to be desired when it comes to features, though consumers who are into sheer numbers might object to the 5MP shooter and lack of HDMI. Otherwise, everything needed is packed in.

Usability: 8.5

Refining Sense UI and tweaking Android has done HTC wonders, making their Android phones among the easiest and most intuitive to use among the competition.

Performance: 9.0

The combination of hardware and software makes for a great user experience. Multitasking and multimedia are well done, making for a well rounded device.

Cost: 8.0

As with any flagship, the Desire comes at a premium. But given HTC’s history and product cycle, the Desire should have some legs should the Froyo update (and more) materialize.

HTC Vision QWERTY Android Spotted In The Wild


HTC Vision

It was only a matter of time before we saw something like the HTC Vision pictured above. Why? The last QWERTY toting handset that HTC released was the Touch Pro 2 and it runs a seemingly ancient, by now, Windows Mobile operating system. Given their rich heritage in professional level QWERTY sliders, it makes sense to finally make one for the Android platform.

First things first, the Vision pictured above is definitely legit as it totes the serial numbers up front that all engineering samples from HTC come with. As you can clearly see in the spy shot, the Vision seems to be some sort of bastard cousin of the Desire and Nexus One, with a framed sliding QWERTY keyboard. Notice that the navigational apparatus at the center seems to be similar to the trackpad that shipped with the original Omnia and E72.

Specswise, we expect this to be similarly equipped as the Nexus One and Desire, with a 1GHz Snapdragon CPU, 576MB RAM, 512ROM, and 5MP shooter with LED flash. If you ask us, announcment will probably be coming Q3, with availability coming in late Q4 or early Q1 2011.

Galaxy S Sequel Leaks, Image And Specs Revealed!


Galaxy S Sucessor

Just as the Galaxy S and its many iterations have been unveiled and launched all over the world, a Russian website (why do the Slavs get these tidbits ahead of everyone else?) has claimed to have the first image and specs of Samsung's next generation flagship and superphone.

As the image above clearly indicates, the updated Galaxy S will now be sporting a larger 4.3-inch display with a resolution of 1280 x 720, while ridding itself of the central button and maintaining the touch screen keys. A front facing camera and proximity sensor are also quite apparent, as it is the dedicated camera key.

Specifications-wise, the site claims that the new model will supposedly tout a 2GHz processor, 1GB RAM, 4GB ROM, 32GB Internal, an 8MP camera with HD video, and Bluetooth 3.0 and WiFi N. On top of all this, Android 3.0 or Gingerbread will run the show. The claimed sucessor is supposedly slated for an early Q1 2011 release. Stay tuned!

Watch Phone Gets Dual Sim, OLED Touchscreen


China Vision CVSL-114 wristwatch phone

The no holds barred Chinese market is teeming with mutations, evolutions, and unholy design marriages we typically refer to as China products. Among these bastardizations is the China phone, which we admit, do arouse our curiosity from time to time. Raving fans of Apple, Nokia, Motorola, and HTC just to name a few won't likely give up their gorgeous manhood extensions for one of these... or will they? Meet the CVSL-114-BLACK, an all-in-one wristwatch phone where you can stick in two SIMs into. When will Q make Bond this sort of gadget?

It's a dual sim triple band phone watch for starters, and it comes with a 1.4-inch (128 x 160) OLED touchscreen, built-in mic and speakers, Bluetooth 1.2, MicroSD card expansion for up to 2GB of extra memory, VGA video camera recorder, WAP data services, and photo and video playback software inside. There's also the usual set of productivity tools found on phones present: calendar, to do, alarm, calculator, unit converter, currency converter, and world clock. It can last for up to 3 days on standby, 5 hours on music playback, and 2.5 hours while using the phone.

To be honest, they're not half bad, unless you take into account of the aesthetics involved. They really need to change those Windows System fonts.

They forgot to stick in a LED projector in there, too.
