Wireless data feed

Post by Sambuchi »

I have been working on a schematic for a wireless data feed between 2 micros over the past couple days and I am near completion...

With a data rate of up to 200Kbps, range of 200ft, standard UART..

Was wondering if anyone else tried something similar and would like to share their expertise... schematics, parts they used, .. ect.

IEEE 802.15.4 modules such as MaxStream's XBee at $20 ea ready to go with AT commands. 250Kbps air link rate, probably nets out at 100Kbps or so.

ZigBee network layer protocol option if you want to get elaborate.

Mod a wireless video camera ... or at least an old TV tuner and "RF video modulator".
Analog television systems use more real bandwidth than any other common signal.

It's easy to get full 1Mbps without overhead from additional layers of abstraction,
just do your own error checking on the receiving end.

It amazes me how some people will go the long way around the world to get to their back yard.
(802.11 is a lot more complex than a UART).
