Brainy Radio
Posted by Janak Parekh in "HARDWARE" @ 02:00 PM
Imagine the following scenario, if you will --
"A personal digital assistant (PDA) falls from its owner's pocket during lunch. After a little while on the restaurant floor, it awakens, calls home, and notifies its owner that it has been left behind. That's all in a day's work for a 'cognitive radio,' a wireless device that's aware of its environment and learns from its user.
Cognitive radios don't exist yet. But Joseph Mitola, a computer scientist at Mitre, in Bedford, MA, aims to make them a reality by exploiting the added processing power that will be built into tomorrow's wireless devices. Mitola is one of the pioneers of 'software radio,' which gives users of cell phones and other two-way radios the ability to use a single device to communicate over a range of frequencies."
There's a lot of DARPA research being done in cognitive technologies, and it seems handheld devices will be a central part of it. Preference management is another exciting field for cognitive PDAs. What do you want your PDA to do for you? Or do you find this too scary?
