4G: USHERING IN REVOLUTION IN DATA TRANSMISSION TECHNOLOGY #Airtel4G

“G stands for generation, 2G means second generation and 3G is third generation”. This was how one of my colleagues tried to explain when I shamelessly exposed my inability to understand these terms. This was about eight years back when 3G came to Indian small towns. I am sure most of the people at that time did not understand the difference between these two terms 2G and 3G although very few admitted it. As I explored I came to learn that 2G was primarily designed for voice communication whereas 3G facilitated data transfer along with digital voice communication. With the advent of 3G technology the era of smart phones started which eased connectivity. The traditional desktop with a wired internet connection (dial up connection) became a thing of the past. 3G Dongles with laptops and smart phones with wifi connectivity became the order of the day. Broadband and speed of download became the talk of the town. And now with Airtel rolling out 4G in India this is the newest topic of discussion everywhere. As experts in the field put it both 2G and 3G networks were designed primarily for voice communications rather than data. On the other hand, 4G is designed especially for data transmission rather than voice. So 4G offers faster access to data using mobile phones. For example, streaming video works better with 4G, with less stuttering and a higher resolution. Similarly, video conferencing and multi-player online games work better with the faster data transmission offered by 4G.
The definition of 4G has changed over the years. Current commercially available technologies LTE (Long-Term Evolution) and WiMax claimed that they are sufficiently advanced from 3G and thus claimed the right to call their technology 4G. The basic fact is 3G and 4G refer to the communication protocol between the mobile handset and the cell phone tower. The throughput rate and browsing speed also depend upon factors such as:
  • how many cell phone towers are in the vicinity
  • how many users are sharing these towers
  • the bandwidth available to  these cell phone towers to connect to the internet.
Pick upload and down load rates are 5mbps/100mbps for 3G and 500mbps/1Gbps for 4G.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.
Anyway, as Airtel is providing 4G services for the price of 3G it is definitely driving the young generation crazy. And what is more, the 4G SIM is available free of cost at one’s door step. Is it not enough to go gaga over it? My son has already changed to 4G with his iphone being compatible with 4G technology. As far as I am concerned I am just watching this young generation dancing to the technological tune. No doubt the new technology will make internet surfing at least 10 times faster if not 100 times. My film freak son says he is able to download full movies in a couple of hours  with 4G which 3G was taking more than 12 hours.
Life will definitely be much faster with 4G. Online shopping, bill payments, money transfers will be done in a jiffy. Watching streaming video without interruption can be a new enjoyable experience.Video conferencing will be faster and more effective for corporate honchos. But I am sure Airtel’s 4G will provide much more than I can think of now. For more information on Airtel 4G click on the link below .
