A system and method are presented for transceiving Time Division Multiple Access (TDMA) telephone communications through a common filter. The system includes a tunable ferro-electric bandpass filter (FE BPF), a controller, a low noise amplifier (LNA), and a power amplifier (PA). The FE BPF has a control input to accept tuning voltage signals from the controller and two signal ports. In response to the tuning voltage signals, the FE BPF selects a transmit or receive frequency passband between the signal ports. The FE BPF first signal port is connected to the LNA and the PA and the FE BPF second signal port is connected to an antenna in a wireless device. The LNA and PA are activated and deactivated in response to control signals from the controller.

System and method for filtering time division multiple access telephone communications

A radio linked vehicle communication system for text messaging, traffic light control, resource management and traffic monitoring, designed to establish the location of emergency vehicles and related privately owned vehicles within their vicinity and have this information relayed to a third party using conventional electronic devices. Specifically to notify the privately owned vehicle or vehicles in close proximity of an emergency vehicle of their presence, so as to avoid possible accidents and to relay this information to a third party to be recorded and verified. Additional benefits of the system would be the ability of having interrogators, either mobile, aircraft of in a fixed location that could identify and personalize specific vehicles for investigation purposes and to provide a mobile repeater system.
