Abstract:
1. A multifunctional base station comprising: a transmit/receive switch; at least one RF processing module, the at least one RF processing module being coupled to the transmit/receive switch; an ultra high-speed transceiver, the ultra high-speed transceiver being coupled to the at least one RF processing module; a codec module, the codec module being coupled to the ultra high-speed transceiver; a signal processing module, the signal processing module being coupled to the codec; a network interface, the network interface being coupled to the signal processing module; a shifting module; and a separate RF processing module; wherein the transmit/receive switch receives an analog signal from an air interface of a wireless network, the analog signal having a spectrum extending from a first frequency to a second frequency, the first frequency being lower than the second frequency; wherein an RF processing module has a band pass filter that passes the spectrum of the analog signal to the ultra high-speed transceiver; wherein the ultra high-speed transceiver has at least one analog-to-digital converter for sampling the analog signal at least at twice the second frequency without the spectrum being shifted in frequency; wherein the codec module adds at least one error code to the digital signal; wherein the signal processing module passes the digital signal to the network interface; wherein the separate RF processing module is further coupled to the shifting module and the shifting module is coupled to the ultra high-speed transceiver; wherein the transmit/receive switch further receives a separate analog signal from the air interface, the separate analog signal having a separate spectrum extending from a third frequency to a fourth frequency, the third frequency being higher than the second frequency and the fourth frequency being higher than the third frequency; wherein the band pass filter of the RF processing module rejects the separate analog signal; wherein the separate RF processing module has a separate band pass filter which passes the separate analog signal; wherein the shifting module shifts the separate spectrum to a shifted separate spectrum, the shifted separate spectrum extending from a fifth frequency to a sixth frequency, the fifth frequency being lower than the third frequency and the sixth frequency being lower than the fourth frequency; and wherein the at least one analog-to-digital converter samples the separate shifted spectrum of the separate analog signal at a separate sample rate of at least twice the sixth frequency.
