The Ericsson 4428 B1 KRC161735/1 Radio is a high-performance, outdoor Remote Radio Unit (RRU) designed for high-capacity macro network coverage in the Band 1 2100 MHz frequency band (B1). It is part of the Ericsson Radio System portfolio, known for its energy efficiency and flexible installation options.
Technical Description of Ericsson 4428 B1 KRC161735/1
The Ericsson 4428 B1 KRC161735/1 is a FDD-LTE unit that employs a 4T4R (4 Transmit, 4 Receive) MIMO configuration. This architecture enhances coverage, boosts cell-edge data throughput, and improves spectral efficiency compared to older 2T2R systems. It is a multi-standard radio that supports GSM, WCDMA, and LTE technologies simultaneously (depending on software configuration) and is designed to be 5G NR-ready via software upgrades (Ericsson Spectrum Sharing). The unit uses passive cooling through a rugged aluminum alloy housing, eliminating the need for fans and improving reliability in outdoor environments (IP65 rated).
