Outstanding Performance

Flexible Framework Design

RG-5GNR-BBU5000 adopts the advanced framework design, with a variety of slots for expansion and evolution. It enables power redundancy and fan hot-swapping.

Evolving Multi-Cell Capacity

Currently, one 5G baseband card supports four 2T2R or two 4T4R 5G cells, and one 4G baseband card supports three 2T2R 4G cells.

The entire device supports up to eight 2T2R or four 4T4R 5G cells in NR and Long-Term Evolution (LTE) frequency division duplex (FDD) modes and three 4G cells, which requires two 5G baseband cards and one 4G baseband card. The device can be evolved to support more cells.

Flexible Cell Merging

This product can merge cells serving by all pRRUs (up to 128 pRRUs) under multiple pHUBs, allowing flexible networking.

Strong Multi-UE Capability

Each cell has 400 or more activated UEs and 1200 or more connected UEs. The entire device supports a maximum of 3200 activated UEs.

Environment Protection and Lower Power Consumption

RG-5GNR-BBU5000 incorporates various new energy saving technologies, including system-level data link design optimization and deep sleep. In addition to high-performance power design, RG-5GNR-BBU5000 is energy-efficient while providing high-speed wireless access services.
