4G is here!

So finally 4G has been launched in India. First City was Kolkatta and Second one is Bangalore. Last time I visited Kolkatta, in 2008, while my hotel had wifi and broadband, most of the people were still using Dial-up connections. So launch of new technology does not means penetration. Apart from cost, the quality of service also matters. Read the following:

In its primer to the media, Airtel says that download speeds on its 4G networks can reach up to 40 mbps and uploads up to 20 mbps, on the move. However, the technical peak speed requirements (prescribed by the International Telecommunications Union – Radio) for 4G service is 100 megabits per seconds (mbps) for high mobility communication (that is while on the move in vehicles) and 1 gigabit per second for low-mobility communication. THE KEY DIFFERENCE Technology-wise, what distinguishes a 4G network from others is that it uses packet data switching techniques (it does not support traditional circuit-switched telephony service). While the frequency used for 2G, 3G and 4G is the same, the modulation differs. Source: http://www.thehindu.com/news/cities/bangalore/article3412720.ece)

So even at the time of launch, the speed of 4G is not upto the mark. These launches are merely symbolic. The 3G, by all the Carriers, has issues. Either it lags or its coverage is uniform. In such situation, such launches have no practical value.It is only conceited self-serving.

BTW 4G the next generation technology which is different from CDMA and GSM and it aims to replace both, eventually.
