Verizon, Ericsson and Qualcomm Technologies have completed a successful FDD Massive MIMO trial with a fully compatible customer device.
This achievement builds on the momentum from the deployment of FDD (Frequency Division Duplexing) Massive MIMO (Multiple Input – Multiple Output) on Verizon’s wireless network in Irvine, California.
In this trial, the three companies used the latest Ericsson Massive MIMO software and hardware on Verizon’s network, along with a mobile test device powered by the Qualcomm Snapdragon 845 Mobile Platform with X20 LTE using TM9 (Transmission Mode 9).
TM9 is an enhancement for consumer devices that will make them fully compatible with Massive MIMO, enabling a better experience. Massive MIMO is a key technology component in the evolution towards 5G. It has the potential of greatly improving network capacity and the customer’s experience.
To realize the gains, both the network and devices need to support new TM9 functionality which leverages advanced beamforming schemes between the network equipment and the mobile device. This will raise network spectral efficiency and customer speeds.
The Ericsson Massive MIMO portfolio is expected to be available next year, putting it well in line with commercial smartphones with the TM9 compatible chipset, which are expected to hit the markets in the first half of 2018.
