Questions:
-speed requirements ?
-security ?
-power consumption requirements ?
-data or voice (i guess data because of -51)
-price target ?
And of course it must be legal.
Frequency bands are country dependant.
Perhaps some of the ISM-bands will do ?
Many manufacturers exists.
Serial interface is convenient to use and there are
ready made solutions (though expensive).
Special attention must be payed to protocol.
Happy projecting...

-data or voice (i guess data because of -51) ? data
