Massive MIMO

Moving from MIMO to massive MIMO, according to IEEE, involves making “a clean break with current practice,” as it requires a large number of service antennas over active terminals, as well as time-division duplex operation. “…By focusing energy into ever smaller regions of space, [Massive MIMO brings] huge improvements in throughput and radiated energy efficiency.” The group calls out other benefits including cheaper parts, lower latency, simplification of the MAC layer, and robustness against intentional jamming.

However, M-MIMO presents deployment challenges as well:

  • Heavier antennas, meaning that existing poles may not be able to bear the load, and any upgrades required will necessitate additional deployment costs
  • Power upgrades, as new active antennas will consume more power, which will be an additional operational cost as well as capital cost
  • Backhaul upgrades are necessary as well, as existing backhaul may not be able to cope with the projected massive increase in data traffic

With Parallel Wireless and its massive MIMO ecosystem partners, MNOs can select hardware based on their 5G deployment cases, budget and subscriber needs. Our OpenRAN Massive MIMO delivers:

  • A compact solution with perfect component synchronization that is easy to deploy
  • Support for any deployment scenario
  • Internal power consumption reduction to achieve total energy efficiency reductions
