Massive MIMO continues to move quickly from science fiction to mainstream reality. In the past week, Ericsson has announced new deals in three continents, while ZTE and Belgium’s Telenet are claiming Europe’s first Massive MIMO roll-out in paired spectrum. Most deployments are still in unpaired (TDD) spectrum in which the technology is simpler to implement and the results are clearer, but over the past year there have also been trials and a few commercial deployments in FDD spectrum, which is still the majority of most MNOs’ airwaves. Ericsson’s latest agreements in this area are with Entel in Chile, SmarTone in Hong Kong, and Verizon in the US. Entel will deploy Massive MIMO for TD-LTE as part of a broader 4G…
