About This Part
The Ericsson KRC161254/2, identified as an RRUS11B4, is a high-performance Remote Radio Unit (RRU) integral to modern cellular network infrastructure. As part of Ericsson's comprehensive Radio System portfolio, this unit exemplifies a compact, energy-efficient, and robust form factor designed for outdoor deployment. Its primary function is to handle radio frequency (RF) transmission and reception, converting digital baseband signals into analog RF signals for wireless transmission and vice-versa. Specifically, the RRUS11B4 variant operates within the Band 4 (AWS) frequency spectrum, typically 1700/2100 MHz, making it suitable for specific regional deployments. It features multiple transmit and receive paths, supporting advanced antenna configurations like MIMO, and interfaces with baseband units via CPRI (Common Public Radio Interface) for high-speed digital signal transfer. This design optimizes signal integrity, reduces feeder losses, and enhances overall network performance by placing the radio closer to the antenna. The Part Number KRC161254/2 is typically deployed at cell sites, mounted on towers, rooftops, or other elevated structures, minimizing the need for extensive shelter space. It seamlessly integrates with Ericsson's RBS 6000 series and subsequent Radio System platforms, providing essential radio access capabilities for 4G LTE networks. Mobile network operators globally utilize these RRUs to expand network capacity, improve coverage in dense urban areas or challenging rural environments, and enhance data throughput for subscribers. By distributing radio functionality closer to the antenna, the RRUS11B4 helps solve challenges related to signal attenuation over long feeder cables, reduces power consumption at the base station, and facilitates quicker, more flexible network upgrades. It serves as a vital component in modernizing existing infrastructure, often replacing bulkier, less efficient traditional radio equipment.
