At COMDEX/Fall '86, Electronic Systems Technology was showing some RF wireless
modems.  The writeup from the program is as follows:

	"Electronic Systems Technology will display the Esteem line of 
	radio frequency wireless modems and the Quest line of wireless
	computers.  Esteem modems allow wireless local area networking
	of computers and their peripherals within a 38-mile radius.  The
	unit, designed for intra-office and building communications, is 
	easily interfaced using the RS232C interface.  The user definable
	baud rate is from 110-9600 baud, with an RF Data rate of 4800 bps.
	The packet radio system handles all flow control and uses a 16-bit
	CRC for error detection and retransmission for error correction."

I do not have any experience with this company, but from the write-up, it
looks like they may have a product that will fit this application.
