hi,
I am working on an FPGA project.
It is a CDMA-based point-to-point communication system; two FPGAs each
works as a transceiver.
The final stage of the project is to send the data via the serial port
(RS-232) to an RF module.
Can any one support me a low-cost, serial (RS-232) Rf module capable of
managing data rates up to 1.25 Mb/s and working reliably within
buildings giving a suitable range ( 10 meters).

Wow, three requirements "low-cost", "serial", and "data rates 1.25
Mb/s via RF " that are all self-contradictory :-).

*And* the device already has CDMA hardware in it.

An ethernet terminal server (ala Lantronics) hooked to a
high-throughput WiFi system might begin to meet what you want, while
you won't get 1.25 Mb/s you might reliably get a tenth of that with
some latency.

I cannot guarantee anything about WiFi interacting with CDMA
performance and in fact I would be pleasantly surprised if there were
zero effect.

Why does the device need CDMA on one side *AND* improbably
high-bandwidth serial via wireless on the other?
