    摘要： A wireless communication device includes a front-end module (FEM) network, an RF connection, and a system on a chip (SOC). A first set of FEMs is operable to output, via an antenna, a first outbound RF signal to a first wireless communication device and receive a first inbound RF signal via an antenna. A second set of FEMs is operable to output, via an antenna, a second outbound RF signal to a second wireless communication device, wherein the second outbound RF signal is representative of the first inbound RF signal, and receive a second inbound RF signal via an antenna, wherein the first outbound RF signal is representative of the second inbound RF signal. The SOC is operable to activate the first and second sets of FEMs, facilitate the first outbound RF signal representing the second inbound RF signal, and facilitate the second outbound RF signal representing the first inbound RF signal.
