About This Part
The Ericsson KRC11891/2, commonly identified as an RRUS11B20, is a critical component within Ericsson's extensive portfolio of radio access network (RAN) solutions. As a Remote Radio Unit (RRU), its primary function is to convert digital baseband signals into analog radio frequency (RF) signals for transmission, and vice versa, facilitating wireless communication. This unit is designed for outdoor deployment, typically mounted on cell towers, rooftops, or poles, close to the antenna to minimize feeder loss and optimize power efficiency. The "B20" designation indicates operation within the 800 MHz frequency band, which is crucial for providing broad coverage, particularly in rural areas or for deep indoor penetration. The KRC11891/2 supports advanced cellular technologies, including LTE, and is engineered for high performance, reliability, and energy efficiency, integrating seamlessly with Ericsson's baseband units via CPRI (Common Public Radio Interface) for robust data transfer and control. Its compact and ruggedized form factor ensures durability in various environmental conditions, making it a cornerstone for modern mobile network infrastructure. The Ericsson KRC11891/2 is extensively deployed by mobile network operators globally to expand and enhance their 4G LTE networks. It is integral to Ericsson's RBS (Radio Base Station) systems, supporting network modernization and capacity upgrades. This RRU is typically installed as part of a distributed base station architecture, where the baseband unit is located centrally, and multiple RRUs are deployed remotely. This configuration optimizes site acquisition, reduces power consumption at the tower top, and simplifies maintenance. Operators utilize the KRC11891/2 to improve coverage in underserved areas, increase network capacity in high-traffic zones, and provide reliable connectivity for a wide range of applications, from standard mobile voice and data to IoT services. Its deployment addresses challenges such as signal attenuation, limited site space, and the need for rapid network expansion, offering a scalable solution for evolving telecommunications demands.
