The Nokia ASIB 473764A is a high-performance baseband system module designed for Nokia AirScale telecom infrastructure. It functions as a core processing unit inside baseband units (BBUs), responsible for handling Layer 1, 2, and 3 signal processing in mobile networks. It supports multiple radio technologies including 2G, 3G, 4G LTE, and 5G NR, enabling SingleRAN deployments across different frequency bands.
This module provides high capacity with support for wideband and narrowband 5G cells, handling thousands of users and multiple cells simultaneously. It includes multiple high-speed fronthaul interfaces such as eCPRI, CPRI, and OBSAI, typically delivered through SFP28 ports for 10G/25G connectivity.
Designed for modern telecom networks, it offers energy-efficient processing, scalable architecture, and modular deployment within AirScale systems. It enables operators to expand network capacity, support massive MIMO configurations, and efficiently manage increasing mobile data traffic, making it a critical component in 4G/5G base stations and mobile network infrastructure.
