Abstract:
1. A communications device comprising: a first physical layer (PHY) unit, the first PHY unit configured to transmit and/or receive data based on a first wireless communications specification; a second PHY unit, the second PHY unit configured to transmit and/or receive data based on a second wireless communications specification; a first signal path coupled to a first antenna and to the first PHY unit, the first signal path configured to perform processing on a signal in the first signal path; and a switchable signal path coupled to a second antenna and switchably coupled to the first PHY unit and to the second PHY unit, the switchable signal path configured to perform processing on a signal in the switchable signal path and to switchably couple the second antenna to either the first PHY unit or the second PHY unit based on a control signal, the switchable signal path comprises a switch control unit coupled to the second antenna, the switch control unit configured to generate the control signal to specify the coupling of the second antenna to either the first PHY unit or the second PHY unit.
