Abstract
A low cost alphanumeric paging entry and page receiving device for entering alphanumeric messages remotely from a telephone and receiving pages via radio frequency signals. The device is designed so that both page reception and alphanumeric page entry can be provided using substantially the same hardware. The entry functionality uses simplex communications, using a system of Baudot tones to send page messages to a paging system for transmission to other similar devices.
