Multi-user IFoF uplink transmission over a 32-element 60GHz phased array antenna enabling both Frequency and Spatial division multiplexing

We experimentally present the A-RoF/IFoF uplink transmission of three 60GHz terminals with 200Mb/s QPSK through a 32-element antenna with beamsteering up to a 60
^o
-angle and 10km fiber, comparing for the first time the frequency and spatial division multiplexing for multi-user uplink for 5G mmWave networks.
