The first wireless interface 202 includes or is embodied as a transceiver for transmitting and receiving RF signals through one or more antennas 201. In some embodiments, the first wireless interface 202 includes or is embodied as a cellular modem or a wireless modem configured to allow the UE 200 to receive wireless Internet access via a mobile broadband connection or a cellular network 220. The cellular network 220 may be 3G, 4G Long Term Evolution (LTE), 5G or 6G. For example, the cellular network may be a packet data network (PDN) in 4G LTE. A mobile Internet user can connect using the wireless modem to a wireless Internet Service Provider (ISP) to get Internet access or IMS services. Referring to FIG. 1, the wireless interface 202 may communicate with a wireless interface 112 of the base station 110 through a wireless communication link 130. In one configuration, the first wireless interface 202 is coupled to one or more antennas 201. In one aspect, the first wireless interface 202 may receive the RF signal at the RF frequency received through antenna 201, and downconvert the RF signal to a baseband frequency (e.g., 0?1 GHz). The first wireless interface 202 may provide the downconverted signal to the processor 204 or the controller 210. In one aspect, the first wireless interface 202 may receive a baseband signal for transmission at a baseband frequency from the processor 124 or the controller 210, and upconvert the baseband signal to generate a RF signal. The first wireless interface 202 may transmit the RF signal through the antenna 201.
