Gamma452 RRU

The product is an advanced single-band outdoor 4 x 40 watt Remote Radio Unit (RRU) that supports operation in GSM and Long-Term Evolution (LTE) modes and is hardware-ready for NR 5G technology. The device operates in a single band and supports up to 4T4R. It also supports both multi-carrier and single-carrier operation modes.

Cooperating with a Base-Band Unit (BBU), the RRU provides customers with advanced, high-performance distributed wireless solutions suitable for a variety of scenarios. It combines multiple technologies to provide wireless outdoor coverage solutions, improving outdoor coverage and capacity while eliminating blind spots at low cost.

The distributed solution (BBU+RRU) is easy to deploy and flexible to configure, effectively meeting outdoor wireless network capacity and coverage requirements.

This product comes with a standard one-year warranty; an extended warranty is available.
