Internet of Things (IoT)


The Internet of Things (IoT) is a scenario in which objects, animals or people are provided with unique dentifiers and the ability to automatically transfer data over a network without requiring human-to-human or human-to-computer interaction. IoT has evolved from the convergence of wireless technologies, micro-electromechanical systems (MEMS) and the Internet.

A thing, in the Internet of Things, can be a person with a heart monitor implant, a farm animal with a biochip transponder, an automobile that has built-in sensors to alert the driver when tire pressure is low — or any other natural or man-made object that can be assigned an IP address and provided with the ability to transfer data over a network. So far, the Internet of Things has been most closely associated with machine-to-machine (M2M) communication in manufacturing and power, oil and gas utilities. Products built with M2M communication capabilities are often referred to as being smart. (See: smart label, smart meter, smart grid sensor)

IPv6’s huge increase in address space is an important factor in the development of the Internet of Things. According to Steve Leibson, who identifies himself as “occasional docent at the Computer History Museum,” the address space expansion means that we could “assign an IPV6 address to every atom on the surface of the earth, and still have enough addresses left to do another 100+ earths.” In other words, humans could easily assign an IP address to every “thing” on the planet. An increase in the number of smart nodes, as well as the amount of upstream data the nodes generate, is expected to raise new concerns aboutdata privacy, data sovereignty and security.

Although the concept wasn’t named until 1999, the Internet of Things has been in development for decades. The first Internet appliance, for example, was a Coke machine at Carnegie Melon University in the early 1980s. The programmers could connect to the machine over the Internet, check the status of the machine and determine whether or not there would be a cold drink awaiting them, should they decide to make the trip down to the machine.

Kevin Ashton, cofounder and executive director of the Auto-ID Center at MIT, first mentioned the Internet of Things in a presentation he made to Procter & Gamble. Here’s how Ashton explains the potential of the Internet of Things:

“Today computers — and, therefore, the Internet — are almost wholly dependent on human beings for information. Nearly all of the roughly 50 petabytes (a petabyte is 1,024terabytes) of data available on the Internet were first captured and created by human beings by typing, pressing a record button, taking a digital picture or scanning a bar code.

The problem is, people have limited time, attention and accuracy — all of which means they are not very good at capturing data about things in the real world. If we had computers that knew everything there was to know about things — using data they gathered without any help from us — we would be able to track and count everything and greatly reduce waste, loss and cost. We would know when things needed replacing, repairing or recalling and whether they were fresh or past their best.”

HTC One – Official Now..!


HTC has proven time and again that it is willing to take a risk. Whether it pays off or not is a different matter altogether. With its latest flagship, the HTC One, which was announced yesterday, the company is banking on enhanced camera capabilities – HTC is calling it an Ultrapixel camera – an improved sound experience and a revamp of its Sense UI. It also brings a full HD display on a screen smaller than 5 inches, a first for a smartphone. 


Does it make a winner though? We will have to wait for hands-on time to figure that out. However, going by the specs sheet, the HTC One is a sumptuous handset that will surely attract some attention over the likes of the Xperia Z and the company’s other 1080p-display-laden offering, theButterfly. Let’s take a deeper look at the specs of the HTC One

OS – Android 4.1 Jelly Bean with Sense 5
It’s great news that Jelly Bean powers the HTC One. Project Butter should go a long way when it comes to delivering a lag-free UI experience. Of course, HTC has injected a bit of Sense into the stock Jelly Bean experience. Sense 5 or the New Sense, as HTC called it last night at the unveiling, is all about the BlinkFeed. This is the new homescreen on HTC’s phones. The company has tied up with 1400 content providers to bring you updates related to sports, current affairs, business, technology, social networking and lifestyle to your BlinkFeed. The BlinkFeed is essentially a vertical scrolling widget, but it is also the page you will see by default when hitting the home key. The feeds are customisable and overall there is a Flipboard-like feel to it. Indeed, this can be called HTC’s re-imagining of Live Tiles from Windows Phone 8. However, users who want a more conventional Android experience can set a more regular homescreen as default. Here, HTC has gone for a more minimal look, closer to the stock experience.

One thing that HTC fans won’t find in the out-of-the-box setup is the trademark Sense flip clock. That’s included as a widget however, with a flatter, more simple-looking clock-weather indicator being the default option.

Cellular Network – LTE-ready
Of course, the HTC One is ready to support LTE networks around the world. But if your region has no 4G infrastructure, it will play nicely with 850 / 900 / 1900 / 2100 bands for HSPA. The phone supports download speeds up to 100Mbps and 50Mbps for uploads. The SIM slot in the HTC One accepts only Micro-SIMs.

Display – 4.7-inch full HD SuperLCD3
The display is one of the highlights of the HTC One. As mentioned above, this is the first phone with a screen less than 5 inches diagonally to have a 1080p resolution. Naturally, text, images and videos look immensely crisp. With a pixel density of 468ppi, you are unlikely to see jagged edges of text or any kind of pixelation, unless you see the world through an electron microscope. The screen itself uses the Super LCD 3 technology, which in the past has ensured vibrant, yet natural-looking hues. Of course, HTC has ensured you don’t cover that awesome display with scratches. There’s Gorilla Glass 2 protection for the 4.7-inch wonder. 

Form factor and weight – Slim, but slightly odd 
Fitting a full HD display on a compact screen has its downsides, but HTC has managed a sublime job at reducing the weight of the handset. The 143 g heft means it’s a lighter smartphone to hold than the Xperia Z, or even the truly bulky LG Optimus G Pro, which weighs in at 160 g. HTC has also managed to fit all the gadgetry in a slim 9.3 mm body, which is a good deal better than the LG handset, but still nowhere near the 7.9 mm-thin frame of the Xperia Z. One area that HTC has sort of mangled is the height of the device. At 137.4 mm, it’s only slightly shorter than the Xperia Z, but considerably taller than the Xperia ZL, which is positively pygmy-esque at 131.6 mm. That and the fact that the power or lock/unlock button is situated on the top of the device could mean a lot of stretching of fingers. 

Another sore point for fans could be the inclusion of only two capacitive buttons below the display. The buttons – back and home – flank a big HTC logo, which is not a button and does pretty much nothing but say you bought an HTC phone. The recent apps screen can be reached by double-tapping the button, while a long-press shows you Google Now. Despite not actually using the device, this setup sounds cumbersome to say the least. A feature like the recent apps screen should be easily reached and a double tap seems like extra work.

Wi-Fi – Everything you expected, and more
In this department, HTC has packed in everything you could have hoped for. The One supports Wi-Fi 802.11 a/ac/b/g/n bands. Multimedia content can be sent to your TV or HTPC thanks to the DLNA support and Wi-Fi Direct can be used to share files with other phones on the same WLAN connection. It also has Android’s standard Wi-Fi hotspot capability to share the phone’s Internet connection with other devices.

SoC – Qualcomm APQ8064T Snapdragon 600 with Adreno 320 GPU
HTC has thrown in the brand-spanking new Snapdragon 600 chipset into the One. That’s the same CPU that was used in the LG Optimus G Pro, but we have not yet seen the raw benchmark scores or the real-world performance of this chipset. Of course, if you have any doubts, please hold them back. The Snapdragon 600 features a quad-core processor clocked at 1.7GHz, which is an upgrade over the insanely fast Snapdragon S4 Pro seen on the Nexus 4 and the Xperia Z. Expect the HTC One to blaze through everyday tasks and even not-so-everyday tasks. If only there were enough apps in the market to take advantage of all this processing power. The powerful SoC will be complemented by 2GB RAM and an Adreno 320 GPU. Both of which should only add to the raw power of the HTC One. 

Internal storage – 32 or 64GB
The internal storage in the HTC One is capped off at either 32GB or 64GB. There is no microSD card slot, so your choice will be final. This could be a sore point for many fans, who normally bemoan the lack of a microSD slot, something that Sony and Samsung have regularly included in their most recent handsets. The HTC One also comes with free 25GB of Dropbox storage.

Primary camera – HTC Ultrapixel camera
HTC wanted to emphasise “less is more” with the brand new Ultrapixel camera. It essentially is a 4-megapixel sensor with enlarged pixels that capture more light and enhance details of a photograph. In the HTC One’s camera, you will find a BSI sensor with each pixel measuring 2.0 microns, larger than those in the iPhone 5, Galaxy S III and Lumia 920, all of which have1.4 micron pixels and considerably larger than the Xperia Z, which has 1.1 micron pixels in its sensor. The company has shied away from the use of megapixels because it claims that the industry has been misleading consumers by launching phones with more megapixels, but not improving the final image quality. The Ultrapixel camera comes with Optical Image Stabilization (OIS), Smart Flash (Five levels of flash automatically set by distance to subject), HDR mode in video recording, continuous shooting and VideoPic, slow motion video recording with variable speed playback. It can shoot 1080p video. Other features include retouching of images after the fact including removing objects, smile detection and sequence shot.

One camera-related feature that HTC is really pushing is HTC Zoe. When in Zoe mode, the camera captures 5 photos before you press the shutter and another 15 after you do. It also shoots a 3-second HD video clip besides giving you the 20 pictures. This gives you short clips with audio, which are called Zoes. These short videos will then be stitched together to create a more immersive and visually impressive clip. A Zoe can be posted to HTC’s site, where it will remain for 180 days. The HTC One will even combine Zoes with animated images, transition effects and music, like an automatic movie editor.

Front-facing camera – 2.1-megapixels with HDR
The 88 wide angle lens on the front-facing camera of the HTC One, means better video calls when there is more than one subject. The camera can shoot 1080p video, which is fast becoming a standard for front-facing cameras. Self-shots will turn out nice with the integrated HDR capability. However, we are not sure anyone would have missed this feature.

Sensors – Accelerometer, gyro, proximity, compass
Nothing new here, but the phone’s capabilities would have been highly affected if they were missing. There is an infrared blaster built into the power key to use the phone as a remote control. HTC has bundled in an app as well to help users take advantage of this feature. 

GPS – Comes with A-GPS and GLONASS
HTC has integrated GLONASS support as well as Assisted GPS. Lack of GLONASS would have been a glaring omission and will certainly improve location lock times on the HTC One. 

NFC
The HTC One has an NFC chip and should play nicely with speakers that have this technology. But the NFC chip might not be present on some international variants of the phone.

Battery – Li-Po 2300 mAh battery
Given the specs of the phone, the battery should have been of a higher capacity, but it is still better than the HTC Butterfly, which only lasted just 6 hours and 40 minutes in our video drain test. If you are a power email user or are constantly browsing on the phone, then the 2300 mAh Lithium polymer battery won’t last the entire day. Of course, we are yet to see how HTC have gone about the power optimisation in the phone, so it could be that the current capacity is more than enough, especially as the Snapdragon CPU is said to be power-efficient. We would have ideally liked to see a 3000 mAh battery and also a removable back cover. But it’s been a long time since we saw an HTC flagship with the latter feature. 

The bottom line
There’s no doubt that HTC has managed to impress us with the specs sheet of the HTC One. It is one beast of a phone with the latest CPU, screen technology and a brand new camera experience. It’s also said to bring a better sound experience than its competitors thanks to the two stereo speakers on the front face. On paper, it sounds delectable. However, things could change by the time we get a chance to review the phone. The Galaxy S4 will be hot on the HTC One’s trail and is expected to be a monster of a phone. Having said that, currently the HTC One is the best-specced handset in the market. 

A couple of things could have been better. The overall design is very reminiscent of the BlackBerry Z10 and the two-button setup seems short-sighted and does present a learning curve for new users. There isn’t a whole lot missing from the spec sheets and indeed the One improves on a lot of specifications of the yet-to-be-launched Xperia Z.

Sony Xperia Z and Tablet Z


Xperia Z :

Sony gave the credit ‘Bond Phone’ to Xperia T but actually Xperia Z deserves the title. Its Dust Proof, Its Water Resistant with Full HD ( 5″ 1080p Display with ~441 ppi pixel density) Screen and it will give out blazing performance with its new Snapdragon S4 Pro, which packs four Krait cores at 1.5GHz, along with 2GB of RAM and Adreno 320 for Gaming performance.

xperia-z-durability-water-resistance

The Sony Xperia Z (previously known by its codename Yuga) is another first for Sony – the company’s first 5″ smartphone.It should come as no surprise that the screen is backed by the second generation of the Sony Mobile Bravia engine for even better image quality. It has got a 13MP shooter and a HDR mode for video, which is a first on a mobile phone. The phone is super slim with a layer of air eliminated and brought the display closer to the lens, for added touch sensitivity and a smaller size. This construction, along with a new component layout and skeleton frame allows for a slimness of 7.9 mm.

Xperia Tablet Z :

The Xperia Tablet Z sports a 10.1-inch screen with full-HD (1920 x 1200) display. It runs on Android 4.1 (Jelly Bean) and packs in a 1.5GHz quad-core Snapdragon S4 Pro processor. The tablet comes with 2GB RAM and 32GB of internal storage, which can be expanded further by a microSD card.

At 6.9mm, the Sony Xperia Tablet Z is currently the slimmest tablet around and weighs 495 grams. Sony also claims that this tablet is waterproof and rustproof and has an 8-megapixel rear camera and a 6,000mAh battery. For connectivity, the Xperia Tablet Z supports NFC and LTE. It will be available in black and white colour options.

It appears as though the Xperia Tablet Z is built with similar materials as the Xperia Z smartphone, which features a glass fibre polyamide construction for the frame. One big difference however, is that the tablet is sandwiched between a sheet of toughened glass on the front, and a waterproof plastic cover on the back. Rather than glass on both sides like the Xperia Z phone. The back cover is non-removable.

iPhone 5 Launched.


iPhone 5, the world’s most awaited gadget, is here. iPhone has been here since 2007, but Apple gave it a completely new Avatar made of glass and aluminium on Wednesday in a bid to take on rising challenges from the Android brigade.

“iPhone 5 is the world’s thinnest smartphone,” Apple’s marketing chief Phil Schiller said. It is also 20% lighter than iPhone 4S. The iPhone 5 sports a larger 4-inch “retina” display, ability to surf a high-speed 4G LTE network. Apple iPhone 5 features a retina display and the screen will have a 1136 x 640 screen resolution, with a 16:9 aspect ratio. 

According to Schiller, the iPhone 5 has a better battery life than 4S. While like iPhone 4S, it features an 8 MP camera, it is 25 per cent smaller. iPhone 5 will run on a quad-core Cortex A6 processor. Apple claims that the processor makes the device twice as fast as its predecessor. 

iPhone 5 will run on Apple’s new operating software iOS 6. The audio system has also been updated to include three microphones. 

Apple, which received a bit of flak on the battery front in the past, seems to have reworked the battery of iPhone 5 with 225 hours of standby time. 8 hours of 3G and 4G LTE browsing, 8 hours of 3G talk time, 10 hours of Wi-Fi browsing, 10 hours of video playback and 40 hours of music play.

So while there is no word on the battery upgrade, its performance in the iPhone 5 has improved, at least statistically.

There seems to be some disappointment in store also for those who were expecting a 12 megapixel camera in iPhone 5. It sports a 8MP rear camera with panorama mode, backside illumination, hybrid IR filter, five element lens, and f/24 aperture.

Other features of the camera include dynamic low light mode, sapphire crystal and precision lens alignment, all of which is enough for iPhone 5 to be taken reasonably seriously for a prosumer camera tag. The front camera in the iPhone 5 for FaceTime will now support HD videos at 720p. It has an aluminium rear sensor and features three microphones – one each at the bottom, top and rear.

Significantly, iPhone 5 will have LTE 4G functionality that will transfer data at much faster rate. The phone will be able to switch between antennae in order to support the network.

It will be interesting to see how the market takes to the LTE-equipped iPhone 5. Rivals Samsungand HTC had a few days ago threatened Apple with patent lawsuits if it ported iPhone 5 with LTE. 

Considering 4G has not been rolled out on a large scale even worldwide, it may not excite buyers in many markets, including India. However, Apple has announced just Sprint, AT&T and Verizon, in the US that will support iPhone 5 with 4G compatibility. It does not include T-Mobile which does not have the LTE offering.

Samsung ATIV S – First Windows Phone 8 device


The Korean giant  announced the world’s first Windows Phone 8 device, the Samsung ATIV S. The news is quite surprising, as the industry was expectingNokia (because of their exclusive partnership with Microsoft), to be the first company to reveal a Windows Phone 8 device, at their September 5 press conference.

As expected, the next generation of Windows Phone devices would finally bring current generation hardware to the platform, and the 8.7mm-thick Samsung ATIV S doesn’t disappoint – it seems to be the device codenamed Odyssey we’d seen last month in leaked Samsung court documents, when Samsung had also launched the Windows Phone 7.5-based Omnia M. It features a 4.8-inch Super AMOLED Gorilla Glass 2 display with a 1,280×720 pixel resolution, a dual-core 1.5GHz Qualcomm Snapdragon S4 Krait (MSM8960) processor, 1GB of RAM, an 8MP rear autofocus camera with LED flash and 1080p HD recording, along with a 1.9MP front camera.

The Windows Phone 8-based Samsung ATIV S will come in 16 or 32GB storage variants. Connectivity options include 3G (HSDPA, 7.2 Mbps; HSUPA, 5.76 Mbps), Wi-Fi 802.11 b/g/n with hotspot & DLNA functionality, Bluetooth v3.0 with A2DP, NFC, GPS with A-GPS and GLONASS, stereo FM radio with RDS, and microUSB. Weighing in at 135 grams, the ATIV S is powered by a rather large 2,300 mAh battery.

On paper, the Samsung ATIV S looks like a capable device to usher in the Windows Phone 8 platform, and with the hardware finally catching, we are eager to see what other manufacturers, especially Nokia, will bring to the table. For now, the pricing and release date of the Samsung ATIV S haven’t been revealed. Stay tuned for more IFA 2012 coverage, including Samsung’s Windows 8 and RT tablets, called the ATIV Tab, ATIV Smart PC, and ATIV Smart PC Pro.

The 4-inch Samsung Windows Phone 8 device codenamed Marco should be unveiled soon as well.
