Fourth Generation networks or 4G is supposed to be the next big thing in digital wireless communications. It is being designed as a full IP-based integrated system made up of a number of diverse sub-systems and network of networks.
Typically, 4G will offer applications like wireless broadband access, MMS, video chat, mobile TV, high definition TV content and digital video broadcasting. Voice and date anytime and anywhere will be child’s play under 4G. 4G technology will offer downloads and upload speeds of 100 mbps while one is on the move and 1Gbps when indoor, anywhere in the world. It’s supposed to be a high-quality service that promises zero hiccups while you are connected. Time will tell how smooth it actually is? If that wasn’t enough, 4G wireless technologies will also offer increased security for all kinds of services anytime, anywhere, at affordable cost. This happens through the convergence of disparate wired networks and devices.
Technologists suggests 4G will also allow 3D virtual reality and interactive video/ hologram images. Globally, technologists and businessmen are still debating the pros and the cons of commercial as well as the technological aspects of 4G.
Blame it on the thorny issues of scarce 3G spectrum — both availability and pricing — which remain unresolved. Accordingly, though all self-respecting telcos from Bharti to Tata Tele to Reliance Communication to Hutch Essar are keen to get cracking on the 3G front, policy glitches have held up its much fancied arrival in India. So it’s time to look ahead, beyond 3G. Perhaps, it wasn’t pure coincidence that Motorola CTO Padmasree Warrior had suggested back in June 2006 that in a scenario where the world had moved to 3G, it would make more sense for India to leapfrog to 4G and wireless broadband technologies. “These are around 1.5 times more cost effective than the current Indian standard,” she had said.
But there’s some serious action on the 4G realm that India’s telecom policy makers are doubtless tracking. For instance, Japan’s NTT DoCoMo’s been reportedly conducting field trials of a 4G communications system prototype at 100 Mbps while moving, and 1 Gbbps while stationary.
So Beware!! we are heading in the right direction with advancing in Technology, but somebody please tell these politicians to Don't make that mess up again like 3G frequency band with these telecom business giants. so just stay away from this technology so that it will not get delayed like 3G.
Howzthattt...!! (tell me)
