Laszlo,

        We use a module from a company called Innomedia.  The make a nice
little OEM RF Transceiver.  There are four to choose from:

        900 Mhz 96K
        900 Mhz 250K
        2.4 Ghz 96K
        2.4 GhZ 250K

Since thier module generates the clock for the data, you would have to step
your data up in your PIC to the 250K.  Darn, have to go faster.  The module
takes care of the spread spectrum and is pretty cheap (around $60 for the
2.4/96 that we use).  If you go that rout and want some help with
implimentation, let me know.  I will tell you that since the company is over
seas, its hard to get support and the documentation is sparse.

I have not used them, but if you do not need bi-directional communications,
they also make individual TX and RX units, as apposed to the transceivers we
use.

Hope that helps.

Hi all,

Any ideas to implement 200 kbps wireless connection between microcontroller
and PC? The distance is about 0.5m (<1m).
