Shipping out next-gen wireless networks can be long and tiresome as the U.S. deployment of 3G has shown. IBM researchers in China have been working on a new network system that will make upgrading existing ones easier.It could lead to wireless networks that could provide better coverage by rapidly adapting to user demand. the new architecture called the Wireless Network Cloud (WNC) marks a step away from using dedicated hardware in the radio base station the serve wireless networks like GSM nd 3G cell phone networks.
All of the signal processing, the modulation and encoding of the signals to and from the physical antennas is done using software radio technology; this allows the network to be managed in a more centralized way using raw signals being relayed to and from multiple antennas called "remote radio heads" via fiber optical from as far as 40 Km away.
The main hook of this project to network operators is cost, traditional bas stations are about 40% of a network's total cost, and when ever a network is upgraded because of it's software used almost all of its equipment has to be replaced.WNC upgrades can be implemented relatively cheaply by installing new software. This also means the centralized nature of this network allows their operators can manage it more efficiently.
Just think about it? we all do it, when we hold are wireless device up to the sky to try to get a better signal the sky will answer back with a 3G network ready to use.
