4G coming to india right away

For average consumers, '3G' and '4G' are two of the most mysterious terms in the mobile technology dictionary, but they're used relentlessly to sell phones and tablets. If you're shopping for a new phone, the answer isn't clear-cut, and you shouldn't always go for the higher number. Our primer will help explain which technology to pick.

First things first, the "G" stands for a generation of mobile technology, installed in phones and on cellular networks. Each "G" generally requires you to get a new phone, and for networks to make expensive upgrades. The first two were analog cell phones (1G) and digital phones (2G). Then it got complicated.

Third-generation mobile networks, or 3G, came to the U.S. in 2003. With minimum consistent Internet speeds of 144Kbps, 3G was supposed to bring "mobile broadband." There are now so many varieties of 3G, though, that a "3G" connection can get you Internet speeds anywhere from 400Kbps to more than ten times that.

Here's a video to see 4g and 3g running live across each other (live speed test between 3G and 4G):

New generations usually bring new base technologies, more network capacity for more data per user, and the potential for better voice quality, too.

4G phones are supposed to be even faster, but that's not always the case. There are so many technologies called "4G," and so many ways to implement them, that the term is almost meaningless. The International Telecommunications Union, a standards body, tried to issue requirements to call a network 4G but they were ignored by carriers, and eventually the ITU backed down. 4G technologies include HSPA+ 21/42, WiMAX, and LTE (although some consider LTE the only true 4G of that bunch, and some people say none of them are fast enough to qualify.)

If you like to surf the Web and especially stream video, 4G can be heaven. If you connect a laptop to your mobile link, 4G makes a huge difference. In general, anything involving transferring large amounts of data gets a big boost from 4G. Watch out for the data limits on your service plan, though; it's easy to use up a lot of data very quickly with 4G.

If your phone is mostly for voice use, you have no need for 4G data. Save money and save battery life by choosing a device without the high-speed network.
If you live in an area that doesn't have 4G coverage, there's no advantage to a 4G phone. In fact, you'll have serious battery life problems if you buy an LTE phone and don't disable 4G LTE, as the radio's search for a non-existent signal will drain your battery quickly.

Here is a chart explaining 2g v/s 3g v/s 4g

Bharti Airtel, India’s largest mobile carrier by subscriber base, is offering high-speed fourth-generation (4G) services packs at lower prices than 3G plans for its customers ahead of the highly awaited Mukesh Ambani's Reliance Jio 4G launch. It is believed that the development comes after Reliance Jio said they would provide 10-12 times faster 4G wireless service compared to 3G networks at cheaper rates which is expected to launch by next year.

So that was about the new term 4G in communication industry. I hope it cleared all the doubts about 4G in your mind. We will come up with related information soon.

Stay tuned to keep yourself updated with this fast moving communication era.

1000 TIMES FASTER THAN 4G!! FATHER OF 4G!!

pCell – the new wireless technology that's 1000 times faster than 4G

Sounds too good to be true? It's launching in San Francisco this year

There are few things more annoying than losing your mobile signal in a crowded area.

Particularly when your smartphone stubbornly insists that you have five bars of signal. The problem is that you're sharing the wireless signal from a single cell tower; all very well if there are only a few people in the area, but as soon as a crowd gathers, or someone starts streaming video, everything goes to pot.

New start-up Artemis Networks reckons that it has the solution: pCells, a new wireless network technology that it claims will deliver data speeds a thousand times faster than 4G LTE.

Current cellular networks use antennas to create individual large cells of wireless signal – carefully spaced to minimise interference. pCell takes the opposite approach, exploiting interference – numerous pWave radios are scattered around an area, combining their signals to create "personal cells" about 1cm large around the antenna of each mobile device. The devices aren't competing for limited spectrum or waiting their turn, and each pCell delivers the full available wireless capacity to its device.

It sounds too good to be true – and as yet, it's only been demonstrated in limited test conditions. One demo video shows four laptops streaming 1080p video at 10 MHz over LTE – together with a pair of MacBook Pros streaming 4K video and outputting on 4K TVs. Another shows eight iPhones simultaneously streaming 1080p HD video in 5 MHz of LTE spectrum.

Sounds impressive – but Artemis faces challenges in getting pCell technology off the ground. There's the creation of a whole new infrastructure of pWave radios, for starters – though they will, at least, be considerably easier to install than cell towers.

And while pCell will be great for users in crowded cities, it'll take a long time to install enough pWave transmitters to give widespread coverage in rural areas, or out on the road. Fortunately, the technology is compatible with LTE, so you should be able to switch seamlessly between the two while out and about. Quite how the phone carriers will react to a technology that makes data consumption easier is also open to question, given that their business models are based around customers paying for data. 

.  Will pCell be more like the former and less like the latter? find out later this year, when it's trialled in San Francisco. A global trial will follow in 2015.
