Herbert, I agree completely.

I found a 2GB-band wireless module controlled by I2C complete with SPI=20
interface
as well as a built-in antenna for $18 for a PAIR of modules. It has 154=20
channels, built-in
encryption/decryption and IN/OUT FIFO (32 character) buffers. Range is=20
supposed to be
100m with the built-in antenna.
