A system, communications device, method and computer program product for implementing antenna diversity may include a first switch to selectively connect a first radio section to one of a plurality of antennas and a second switch to selectively connect a second radio section to one of the plurality of antennas. The system may also include an antenna detector to detect which one of the plurality of antennas is connected to a port of the first radio section and to a port of the second radio section.

System and method for implementing antenna diversity

A wireless communication terminal includes a broadcast signal frequency converter that is communicatively coupled to the terminal's communication signal receiver and is configured to use its communication receiver to process received broadcast signals. In an exemplary embodiment, the converter includes a frequency shifting circuit, e.g., a block frequency converter, that shifts broadcast signal bands into communication signal bands, such that received broadcast signals are shifted into a frequency range compatible with the communication receiver's signal path. Moreover, the significant digital domain signal processing capability of the communication receiver can be used to receive broadcast television and/or radio signals, provide signal enhancements, and extract other types of information such as RDBS, IBOC, etc. Further, the terminal can be configured to maintain communication network monitoring while receiving broadcast signals by switching the receiver back to a communication network signal long enough to check for pages, etc.

Low cost method for receiving broadcast channels with a cellular terminal

A wireless communication module for wirelessly communicating with other devices a control pin for controlling at least one function of the communication module, an input device operatively coupled to the control pin, wherein actuation of the input device toggles a signal on the control pin between one of two different states, and a hardware reset circuit configured to implement a hardware reset of the communication module. The control pin is operatively coupled to the hardware reset circuit to at least partially implement the hardware reset, the hardware reset being different from the at least one function.

An improved network interface device includes at least two wireless network transceivers where the transceivers share at least one antenna. In one embodiment, one of the transceivers is a 2&#xd7;2 MIMO WiFi N transceiver and the other of the transceivers is a 2&#xd7;1 MIMO WiMAX transceiver. A priority selector and lockout control circuit is used to control which transceiver has access to the shared antenna. The control circuit of one embodiment is arranged so the WiMAX transceiver is given priority access to the shared antenna.

Network interface device with shared antenna

An apparatus comprises a transmitter, a receiver, an antenna and a signal cancellation circuit. The transmitter is configured to send a transmitter signal associated with a frequency. The receiver is associated with the frequency. The antenna is coupled to the transmitter and the receiver. The signal cancellation circuit is coupled to the transmitter, the receiver and the antenna. The signal cancellation circuit is configured to phase shift a first portion of the transmitter signal to produce a phase-shifted signal. The signal cancellation circuit is configured to combine the phase-shifted signal with a second portion of the transmitter signal to produce a combined signal. The second portion of the transmitter signal is associated with a reflection of a third portion of the transmitter signal from the antenna. The first portion, the second portion and the third portion of the transmitter signal are different from each other.
