Radio-on-a-chip

Radio-on-a-chip or RoC systems are single-chip devices that incorporate a receiver, an amplifier, and power management into a single chip, which can thus be embedded into very small or even portable electronics.

Of all System-on-a-chip implementations, RoC holds some of the greatest promise for computer networks, due to the chip's ability to act as a Wireless access point. It has been suggested that these devices could solve the problem of the last mile, since any area with reasonably high population density would have a plethora of nearby access points [http://www.econlib.org/LIBRARY/Columns/Klingwireless.html .]
