I'm planning to develop a 802.11b based transceiver module as a hobby
project. I have a Microsoft 802.11b based LAN kit (PCMCIA + base
station) and I plan to use it for testing the (hopefully) built
The thought-of design is to use a chipset which performs the
functionality of the RF and baseband constituting the hardware
portion. The 802.x and the TCP/IP stack would form the software
1) Which are the low-cost chipsets available for the above mentioned
functionality and what would be their approximate price ?
2) Is any 802.x stack available in public domain (I assume the TCP/IP
stack is) ? If not what would be its approximate cost ?
3) How complex would it be to implement the 802.x stack ? This is in
case there is no open source and the commercial one is too expensive
from a hobby project viewpoint.
