Intel Wi-Fi in a chip
p2pnet.net News:- Intel says it’s developed the prototype of an all-CMOS direct conversion dual-band radio transceiver chip able to support every current Wi-Fi standard (802.11a, b and g), as well as the projected requirements of 802.11n.
“A future extension to the Wi-Fi standard, 802.11n will more than double the wireless transfer speed compared to today’s implementation,” it promises.
The new system, “uses more low-voltage circuitry than we’ve ever used in the past, which means we can integrate it and make it lower cost while operating at lower voltages and providing longer battery life," says Krishnamurthy Soumyanath, director of Chipzilla’s communications circuits research lab.
"The variable bandwidth of this solution extends capabilities beyond today’s 20 MHz to 100 MHz, and is expected to support data rates higher than 100 megabits per second that should allow people to enjoy multiple high-quality video streams concurrently."
The technology integrates a 5GHz CMOS power amplifier that meets all the spectral purity and non-interference requirements from the US Federal Communications Commission (FCC), while frequency planning techniques minimize interference caused by the on-die amplifier, states Intel, adding:
“To achieve these results, Intel researchers developed a new calibration scheme for the transceiver to achieve high volume manufacturability. Separating receiver and transmitter effects has proven to be difficult in the past, but Intel’s scheme is easy to implement and correctly separates the effects, improving yields and lowering the cost of these radios.”

There was a chip that was supposed to come out that would have provided up to a 30 mile range. I guess I ran my mouth too much about FreeWan. I wonder what it took for the communication cartels to quash that.
