Abstract

A multi-modular terminal device enables simultaneous communications over multiple wireless networks. The terminal device includes a first duplexer connected to a first transceiver corresponding to a first wireless network of the wireless networks, and a second duplexer connected to a second transceiver corresponding to a second wireless network of the wireless networks. A first antenna is connected to the first duplexer for receiving and sending first signals to and from the first transceiver, and a second antenna is connected to the second duplexer for receiving and sending second signals to and from the second transceiver. The first duplexer reduces interference caused by the receiving and sending of the second signals, and the second duplexer reduces interference caused by the receiving and sending of the first signals.
