Ericsson RUS-02B8

The Ericsson RUS-02B8 is a compact and energy-efficient Remote Radio Unit (RRU) designed for mobile network deployments operating in the 900 MHz frequency band (Band 8). As part of the Ericsson Radio System, it delivers high-quality LTE, WCDMA, and GSM radio performance while minimizing site footprint and power consumption. The RUS-02B8 is optimized for both coverage and capacity, making it ideal for suburban and rural areas where wide-area signal propagation is essential.

The unit supports 2x40 W output power and 2x2 MIMO configuration, ensuring improved spectral efficiency and enhanced data throughput. It connects to Ericsson Baseband Units (such as the 6630 and 6648) through CPRI or eCPRI interfaces, allowing flexible integration in both legacy and modern multi-standard networks.
The RUS design (Radio Unit Small) emphasizes lightweight construction and simplified installation, reducing the need for external shelters or active cooling systems. Its IP65-rated enclosure ensures reliable operation in harsh outdoor environments, including exposure to rain, dust, and extreme temperatures.

The Ericsson RUS-02B8 supports software-defined functionality, enabling remote upgrades and easy adaptation to future radio technologies, including 5G migration. This unit helps operators optimize operational costs, energy efficiency, and overall network performance.
