In the September 21st issue of Infoworld they had a short article on page 14 entitled "Wireless LAN Communicates At 19.2 KBPS Within 300 feet". The unit was developed jointly by Technology Development of Spokane, Washington, and Ray-Net Communication Systems Inc. of Vancouver, BC. Quoting from the article: "Ray-LAN uses Novell Netware-compatible software and includes an adapter card and independent, video-cassette-size RF transceiver for each computer. Inside a building, computers within 300 feet of each other communicate at 72 MHz at speeds up to 19.2 kilobits per second." It's to be available Q1 of '88. And supposedly the system will allow a user to work from home "at distances up to five miles given proper conditions". FCC licensing is supposed to be a one-time deal for a whole network.
