what about CSR's Unifi? It is specially made to co-exist with the bluetooth chip you are already using. http://www.csr.com/products/unifirange.htm

As far as I know, one of the best products when it comes to powerconsumption vs. signal strength.

And if you have requirements, just say what they are! How many milliamperes standby/inactive/RX/TX is the maximum?

How many square millimeters or whatever shape is the maximum?

"Too Big" and "Too Much" aren't engineering units.

The smallest units I could find were the Symbol LA-5127 which are Compact Flash cards, and the earlier (802.11b only) version was several times better than any other CF WiFi card and it has GPL drivers (with snort extensions). But it still takes 500mA for transmitting, but maybe they can limit the Tx power (100 milliwatts of RF would mean V*mA would be 100 at perfect efficiency).

Are there any closed-source chips that you can use? Socket I think has an SD card format WiFi, but I don't know the power or size for that either.

There is the Philips BGW 21x family: http://www.nxp.com/products/connectivity/wlan/index.html

or the similar ( might be same chip) from connexant CX53121: http://www.conexant.com/products/entry.jsp?id=408

Philips (NXP) seems to have Linux drivers for these chips.

If you are going to list the TI chipset(which most likely will never be supported w/ a GPL driver) might as well list the Broadcom wifi chipset BCM4326 and BCM4328

Broadcom

Does sombody know if the unofficial Broadcom GPL driver from http://bcm43xx.berlios.de/ supports the Broadcom BCM4318E chipset which is especially for phones?

I Dont Know About the BCM4318E chipset but the BCM4326 supports Linux and must meet the project's needs for a Wifi Solution

Also Take a look at http://www.broadcom.com/collateral/pb/4326-PB02-R.pdf Surajram 00:26, 15 March 2007 (CET)
