简要描述：
RRU 4428 B3 (KRC 161 713/1) The Ericsson RRU 4428 B3 (Model KRC 161 713/1) is a high-performance Remote Radio Unit (RRU) designed for LTE Band 3 (1800 MHz, FDD) deployments. As part of Ericsson’s advanced Radio System, this unit provides superior network coverage, signal quality, and data capacity for large-scale macro cell deployments.
The Ericsson RRU 4428 B3 is part of Ericsson’s macro radio line designed to support LTE Band 3 (1800 MHz, FDD) deployments. It is engineered to deliver strong coverage, capacity, and performance in both urban and suburban environments.
Frequency Band: Operates in LTE Band 3 (1800 MHz), a common band for many LTE deployments.
Radio Configuration: Likely supports 4T / 4R (4 transmit, 4 receive) architecture, which helps improve throughput and spatial diversity.
Output Power: Capable of delivering 4 × 40 W output power (i.e. 40 W per transmit branch).
Compact Form Factor: Dimensions are often cited around 420 × 335 × 125 mm.
Interface & Connectivity: Includes fiber-optic interface to connect with baseband units. Supports extended link distances and cascading/star configurations.
Outdoor Durability: Designed with weatherproof enclosure (likely IP65 or similar rating) for outdoor macro cell deployment.
