About This Part
The Nokia 472261A is a sophisticated Remote Radio Head (RRH) designed as a critical component within modern cellular radio access networks (RAN). As part of Nokia's extensive portfolio of wireless infrastructure, this unit exemplifies a compact, weather-resistant form factor, typically deployed outdoors on poles, masts, or rooftops. Its primary function is to efficiently convert digital baseband signals received via optical fiber from a Baseband Unit (BBU) into high-frequency radio signals for transmission through antennas, and vice-versa for reception. Specifically operating in Band 1 (2100 MHz FDD), the 472261A supports vital frequency spectrum for 3G and 4G LTE deployments globally. Key technical specifications include its high power efficiency, multi-carrier support, and advanced RF processing capabilities, often incorporating multiple transmit and receive paths (e.g., 2T2R or 4T4R) to facilitate MIMO (Multiple-Input Multiple-Output) performance and enhance spectral efficiency. Connectivity to the BBU is typically achieved via CPRI (Common Public Radio Interface) over optical fiber, ensuring high-speed, low-latency data transfer. The Nokia 472261A RRH is strategically deployed at the antenna level, minimizing feeder loss and maximizing signal integrity, which is crucial for optimizing network performance and coverage. It is an integral part of 4G LTE networks, seamlessly integrating with Nokia's AirScale or Flexi BTS baseband units to form a distributed RAN architecture. Mobile network operators (MNOs) worldwide utilize this type of equipment to expand network capacity, improve coverage in dense urban environments, fill coverage gaps in suburban or rural areas, and enhance user experience in high-traffic venues. By bringing the radio processing closer to the antenna, the 472261A helps solve challenges related to signal degradation over long coaxial cable runs, enabling more flexible and cost-effective site acquisition and deployment. It serves as a vital upgrade path for existing infrastructure or a foundational component for new network buildouts, supporting the continuous evolution of mobile broadband services.
