Abstract: This paper describes the advances and features of future cellular base stations. Software defined radio (SDR) evolves to cognitive radio (CR), which is smart and has wideband, and multiband radio (MBR) with reconfigurable wideband can be regarded as the basis of CR and an advanced level of SDR. Based on the SDR platform, several radio frequency (RF) solutions for implementing MBR systems are proposed, and some challenges to MBR implementation are discussed.
