EasyPhone Inc, San Jose has come up with a new Personal Communications Network technology that it claims solves problems that arise with the spread-spectrum technology now being offered: EasyPhone’s PCI system sends a call on the microwave band in many directions at once, and, rather like CSMA/CD in Ethernet, if it senses interference it moves to another channel; according to the Teleputing Hotline, it is an adaptation of the Cordless Telephone-2 technology used in the UK, and makes use of the vacant 930MHz to 931MHz and and 940MHz to 941MHz bands and enables frequency sharing with fixed microwave users at 900MHz to 1GHz; the company says it wants to test the technology in San Francisco and in Los Angeles.
