I'd definitely recommend to buy WiFi modules (e.g. pci-e) or off-the-shelf boards with WiFi SoCs on it. If you don't have experience in building WiFi routers, you might have a lot of fun otherwise. :)
The issue is that the stations need to be very low power, so I'd like to leave everything out which draws power but isn't absolutely needed. The HF part should be solvable, that's something the hardware developers have experience with. I'm aiming for a low power ARM cpu, which basically rules out anything that needs PCIe and leaves us with SDIO or USB for the connection of the transmitters.
I'm hoping i can get my hands on one of these soon:

There is a kernel patch around for one of the Yocto kernels, which i expect you guys would have no trouble cleaning up.
Nice little system. I already have the TI WiLink chips on my list of possible devices (we have an older one on an SDIO card for testing).
Thanks for the pointer!
For an complete solution you can have this nice device:
