Do you use radio's as only a source of entertainment if you do so please stop and
HAVE A LOOK AT THE AMAZING WONDERS WHICH A LITTLE THING COULD CREATE
When the technologies were dominated by the likes of robots, nanogadgets and supercomputers on a chip, the subject of radio might was seeming a tad boring.
But still software-defined radios and cognitive radios were more promising for making our wireless networks powerful and useful.
I want to say not to regard radios as individual, discrete units, rather as members of a community.The idea is all about replacing much of the hardware in radio frequency devices -- cell phones, GPS unitsand even wireless laptops.
Cognitive radios go a step further by being aware of their environments. The most important application in the near term is to enable a wireless device to automatically and rapidly hop from frequency to frequency looking for uncongested slices of the radio spectrum.
Cognitive radios in a local area work on an ad hoc basis with one another, rather than taking direction from a central router, server or cell tower. They can "vote" among themselves -- dynamically, and based on local conditions such as hot spots and dead spots.This is called as virtuous cycle.
Won't it be like cell phones be working on their way like automatically detecting and jumping to a much faster Wi-Fi network in a local hotspot.
