I am trying to find (build/buy) a low-cost wireless data link to connect
a robot to its host computer. I only need 1200 baud (or better) and a
hundred feet of (indoor) range.  I have talked to commercial vendors
that sell spread-spectrum (unlicesed) wireless modems which are perfect
except very expensive (over $2000).  Also, packet radio is possible
but required an FCC license, is not particlularly cheap, and has
latency problems.

I was wondering if I could use low-cost (kids) walkie talkie's with
an FSK modulator-demodulator (or maybe a 1200 baud modem) to send/receive
data over a short range ???

Can anyone suggest if this might work or perhaps another solution ???


Thanks,
