they do have great stuff , but to kip it simple I was hoping to find a
small board with as many parts ,that I need, as possible ; if not for the
WSN802GC transceiver with integrated SoC I would've went with a pc32 mcu
and a MRF24WB0MA transceiver both from microchip. thank you anyway

Thats just what i needed , searching for "wireless Ethernet module" gave me
the right result :D
http://www.rfm.com/products/spec_sheet.php?record=WSN802GC (1 square inch)
and its perfect for the first stage testing. I've looked at a few small
form factor computers similar to the pc-104 , as beagleboard pico-itx and
mobile-itx but in all cases they're just an extreme overkill. Thank you !

See if you can find a wireless Ethernet module that will talk serial 
on-board and 802.11b to the outside world.  Then you should be able to 
do the rest of it with a simple processor such as a PIC or one of the 
new itty bitty Cortex ARM parts that are popping up in low-pin-count 
packages these days.

How easy it'll be to integrate will depend heavily on the Ethernet 
module, of course, and whether that 5cm x 5cm requirement is do-or-die, 
or if it's just a preference.  (This would be simple with a PC-104 
stack, IHMO).

 For my bachelor project i need a device capable of collecting data from
sensors and transmit it through a 802.11b transceiver to a pc. I've worked
until now only with software high and low-end programming but never with
hardware ; I've started reading and looking through tons of stuff but I
failed at finding a small factor , max 5cm x 5cm board with an mcu , power
regulator (as the device has to work with batteries and be as mobile as
possible). A solutions as MotionBee would have been perfect but i need the
rf transceiver to work with 802.11b standard so that it would communicate
with normal wireless routers not only with 802.15.4 ones . A SoC would be
perfect and if it had an LCD controller even better but thats optional; the
3 sensors when in use are having a response time of 0.002 ms , and after
resolving this issues i would like to port a part of the computation to the
device so the mcu should be around 40/80 mhz with as much ram as possible .
Maybe someone with more expertise could help , guide me in the right
direction .
