<p>An apparatus, system and method for effective radio frequency spectrum allocation in a multi-system cellular communication network. According to the present disclosure a Base Transceiver Station, User Equipment and Base Station Controller of a cellular communication network includes at least one pair of radio frequency transceivers. The transmitter of the RF TRXs (radio frequency transceivers) is configured to operate in a downlink frequency from any one of the guard bands: 915 to 935 MHz, 1785 to 1805 MHz, 849 to 869 MHz, and 1910 to 1930MHz; and the receiver of the RF TRXs is configured to operate in an uplink frequency from another one of said guard band. Further, the transmitter or receiver of the RF TRXs is configured to operate in a frequency band within any one of the guard bands: 915 to 935 MHz, 1785 to 1805 MHz, 849 to 869 MHz, and 1910 to 1930MHz. Similarly, the transmitter or receiver of the RF TRXs is configured to operate in a frequency band outside of all said guard bands. The outside frequency bands are: 890 to 960 MHz, 1710 to 1880 MHz, 824 to 894 MHz and 1850 to 1990 MHz.</p> |
