Nokia ARGA B1 474800A RRU

The Nokia ARGA B1 474800A is a high-performance remote radio head (RRH/RRU) from Nokia’s AirScale Radio Access portfolio, engineered to operate in the 2100 MHz frequency band (Band 1). Widely deployed for WCDMA (3G) and LTE (4G) services, Band 1 is also an important spectrum layer for 5G NR rollouts, making the ARGA B1 a future-ready solution for operators expanding capacity and coverage while ensuring smooth network evolution.

Supporting multi-standard operation, the ARGA B1 can simultaneously handle LTE, WCDMA, and 5G NR-ready features, enabling flexible spectrum utilization. With its typical 2T2R MIMO configuration and high output power per port, the unit delivers strong coverage, excellent indoor penetration, and efficient spectral performance. This makes it suitable for a wide range of deployment scenarios — from dense urban hotspots to suburban and rural areas. The radio integrates with Nokia’s AirScale baseband units via CPRI or eCPRI fronthaul interfaces, offering transport capacities up to 10 Gbps per port. This ensures fast, low-latency data transfer and seamless compatibility with both traditional distributed RAN and modern cloud-RAN (vRAN) architectures.
