Abstract

A wireless telephone jack that uses the 49 MHz frequency band as allowed by the FCC (47 CFR 15.233). This jack supports both voice and data communication and operates as a convenient means for providing telephone device communications in locations where telephone wiring is limited or unavailable. A base station is provided to connect to the telephone lines, or a central office, which has an RF transmitter and receiver for communicating with a provided extension unit, which also has an RF transmitter and receiver for communicating with the base station. This invention is designed to work with standard telephone communication signals and standard telephone equipment.

Claims
