Entel, Huawei complete TDD cell capacity verification on 4G network

Entel, a telecom operator in Peru, completed the TDD ultra-large cell capacity verification on commercial 4G networks.
Gonzalo Veas, CTO, Entel PeruHuawei said 40 outdoor CPEs using Huawei’s latest technology accessed a 20 MHz Massive MIMO cell. The cell throughput exceeded 1.5 Gbps, more than twice the industry’s average of 700 Mbps, which will provide effective support for operators to develop mobile Internet and wireless broadband access services.

“Our partnership with Huawei has enabled improvement in our network quality. This joint verification has achieved strong results,” Gonzalo Veas, CTO of Entel Peru, said.

Entel Peru’s TDD Massive MIMO rollout in 2018 has resulted into a significant increase in both 4G user numbers and revenue. This has motivated the operator to use WTTx as an essential strategy for growing its user base, with the goal of extending home broadband to one million households in three years.

Huawei will provide an innovative solution featuring coordination between Massive MIMO and outdoor 8R CPEs. The CPE product uses HiSilicon chips, supporting SRS 4-antenna selection that enables precise channel information feedback. It will be the industry’s first Gigabit CAT19 CPE product that has been commercially deployed on a large scale.

Huawei’s Massive MIMO base station has achieved an innovative algorithm breakthrough for WTTx, improving cell spectral efficiency. Beamforming performance improves substantially, particularly in terms of the number of paired UEs for multi-user MIMO (MU-MIMO). This enables the same time-frequency resources to be allocated to more UEs, significantly improving downlink capacity.
