Abstract
A method includes: receiving MIMO channel signals at original MIMO frequency from signal source(s) at master unit of DAS, set(s) of the MIMO channel signals including first MIMO channel signal and second MIMO channel signal; generating local oscillator signal at master unit; frequency converting first MIMO channel signal(s) and second MIMO channel signal(s) from original MIMO frequency to different frequency different from first legacy service frequency band using local oscillator signal at master unit; combining first MIMO channel signal, second MIMO channel signal, and local oscillator signal into combined signal at master unit; transmitting combined signal across optical link to remote unit; processing first MIMO channel signal and/or second MIMO channel signal at remote unit; and frequency converting converted MIMO channel signal(s) from different frequency different from first legacy service frequency band back to original MIMO frequency for transmission over antenna(s).
