Massive MIMO is one way for operators to address the problem of congestion without the need for cost-intensive network densification or investment in new spectrum and radios.


  • Massive MIMO works by employing a large number of antenna arrays. Its use started with TDD networks and is now being extended to FDD.
  • A number of operators around the world are already well advanced in their trials and early commercial implementations of massive MIMO. Many of them are also planning its use with 5G.

Features and Benefits

  • Explains the principles of massive MIMO and how it can improve network capacity and coverage.
  • Discusses how operators are starting to use massive MIMO in their networks, and what vendors are doing to support product development.

Key questions answered

  • Which vendors are supporting massive MIMO and what solutions are they supplying to the market?
  • What will be the role of massive MIMO in 5G?
