Abstract
A distributed antenna system, comprising: master unit configured to: receive MIMO channel signals at MIMO frequency from signal source, MIMO channel signals including first and second MIMO channel signals; generate LO signal; frequency convert first and/or second MIMO channel signal from MIMO frequency to different frequency close to first legacy service frequency band using the LO signal; combine first MIMO channel signal, second MIMO channel signal, and LO signal for transmission; optical link operably coupled with master unit; unit communicatively coupled with master unit via optical link for transceiving first second MIMO channel signal, unit including band processing circuitry configured to process first and second MIMO channel signal; conversion circuitry configured to receive converted MIMO channel signal and to frequency convert converted MIMO channel signal from frequency close to first legacy service frequency band back to MIMO frequency for transmission over antenna.
