Holographic beamforming for 5G

As we have reached the Shannon limit in terms of squeezing bits in a single Hz researchers are looking at circumventing that limit by using several parallel “channels”.  This is what happens with MIMO, Multiple Input Multiple Output. The radio signal is generated from and received by multiple antennas (this …
