Abstract
A system and method for providing wireless access to a telephone line of a telephone network utilize a mobile terminal and a crossconnect base station. The mobile terminal transmits a radio frequency signal carrying a telephone communication. The crossconnect base station connects to a telephone line at a crossconnect box of a telephone network, receives the radio frequency signal carrying a telephone communication, and communicates the telephone communication over a connected telephone line. Other aspects of the system and method of the present invention include: (1) providing a wakeup signal from the mobile terminal to the crossconnect base station so that the base station can be powered down when not in use, thereby conserving energy; (2) receiving both the wakeup signal and the primary communication signal (which can carry data and/or voice) through a single antenna connected to the base station at the respective crossconnect box; and (3) recharging one or more batteries in the base station from an energy source of the telephone network.
