Reconfigurable multi-mode and multi-bands radio architecture and transceiver

A wireless device comprising:

• a transceiver comprising:
• a spectrum sensing unit configured to select, within a plurality of millimeter wave bands, one or more channels with tolerably low interference and select a duplexing operating mode based on the selected one or more channels, the duplexing operating mode selected from frequency division duplexing and time division duplexing;
• a transmitter configured to modulate a transmit signal using a transmit carrier frequency within the selected one or more channels, and using the duplexing operating mode;
• a receiver configured to demodulate a receive signal using a receive carrier frequency within the selected one or more channels, and using the duplexing operating mode;
• and
• a duplexer configured to route the transmit signal from the transmitter based on the duplexing operating mode, and the input receive signal to the receiver based on the duplexing operating mode;
• an antenna connected to the transceiver for transmitting the transmit signal and receiving the receive signal;
• and
• a processor and a memory for sending data to the transceiver to generate the transmit signal and receiving and storing data from the transceiver from the receive signal.

A method for transmitting and receiving signals within a plurality of millimeter wave frequency bands, the method comprising:

• continuously scanning the channels of each of the plurality of frequency bands to select one or more channels with tolerably low interference and select a duplexing operating mode based on the selected one or more channels, the duplexing operating mode selected from frequency division duplexing and time division duplexing;
• modulating, using a transmitter, a transmit signal using a transmit carrier frequency within the selected one or more channels, and using the duplexing operating mode;
• demodulating, using a receiver, a receive signal using a receive carrier frequency within the selected one or more channels, and using the duplexing operating mode;
• and
• routing, using a duplexer, the transmit signal from the transmitter based on the duplexing operating mode, and the receive signal to the receiver based on the duplexing operating mode.

A backhaul communication system for wireless devices comprising:

• a plurality of base stations in wireless communication, each base station comprising at least one antenna and at least one transceiver for the wireless communication, the at least one transceiver having:
• a spectrum sensing unit configured to select, within a plurality of millimeter wave bands, one or more channels with tolerably low interference and select a duplexing operating mode based on the selected one or more channels, the duplexing operating mode selected from frequency division duplexing and time division duplexing;
• a transmitter configured to modulate a transmit signal using a transmit carrier frequency within the selected one or more channels, and using the duplexing operating mode;
• a receiver configured to demodulate a receive signal using a receive carrier frequency compatiblo within the selected one or more channels, and using the duplexing operating mode;
• and
• a duplexer configured to route the transmit signal from the transmitter based on the transmit duplexing operating mode, and the receive signal to the receiver based on the receive duplexing operating mode.
