Abstract
A wireless module with reduced interference between the multiple wireless antennas therein. A synchronization signal is transmitted from a first transceiver module to a second transceiver module and, accordingly, the second transceiver module operates a transmitter of the second transceiver module at a first operating bandwidth in a time-division mode (with respect to the first transceiver module). The second transceiver module further operates the transmitter of the second transceiver module at a second operating bandwidth in a frequency-division mode (with respect to the first transceiver module).
Claims18
A wireless device, comprising:
- a first transceiver;
- and
- a second transceiver, receiving a synchronization signal from the first transceiver to operate a transmitter of the second transceiver at a first operating bandwidth in a time-division mode,
- wherein:
- the second transceiver operates the transmitter of the second transceiver at a second operating bandwidth in a frequency-division mode;
- the first transceiver predicts when to restart transmitter-receiver duration of the first transceiver and outputs the synchronization signal to the second transceiver to indicate a remaining time before the restarted transmitter-receiver duration;
- and
- the transmitter of the second transceiver is operated at the first operating bandwidth when the remaining time is sufficient.
A method for reducing interference between a first wireless antenna and a second wireless antenna, comprising:
- transmitting a synchronization signal from a first transceiver corresponding to the first wireless antenna to a second transceiver corresponding to the second wireless antenna and thereby the second transceiver operates a transmitter of the second transceiver at a first operating bandwidth in a time-division mode;
- applying the second transceiver to operate the transmitter of the second transceiver at a second operating bandwidth in a frequency-division mode;
- applying the first transceiver to predict when to restart transmitter-receiver duration of the first transceiver and thereby the first transceiver outputs the synchronization signal to the second transceiver to indicate a remaining time before the restarted transmitter-receiver duration,
- wherein the transmitter of the second transceiver is operated at the first operating bandwidth when the remaining time is sufficient.
