AirScale Baseband

Efficiency, flexibility and scalability for the 5G era


Space- and energy-efficient, high-performance baseband processing for 2G, 3G, 4G and 5G leveraging common systems for all radio cells on low, mid and high (millimeterWave) frequency bands.

AirScale system module

This baseband module is designed with an agile yet long-term network evolution in mind. The in-node modularity of the AirScale System Module is key to lean entry and decoupled scalability of the compute power for radio access network layers 1, 2, and 3 and integrated transport functionality – essential for the rapidly changing traffic requirements of new use cases and deployment scenarios of the 5G era.

The AirScale System Module simplifies 2G, 3G, 4G and 5G Single RAN deployments, streamlines multi-band sites and powers multi-site baseband hotels.

The concept of in-node scalability through addition and coexistence of Single RAN plug-in cards for base and high capacity requirements optimizes total cost of ownership (TCO). Plugging-in the latest cards, when and where additional frequency layers or network densification demand the extra capacity, ensures access to the latest and most efficient technology, while maximizing the use phase of the installed base. 

New generation AirScale baseband plug-in cards – Introducing AirScale Chinook, AirScale Fremantle and AirScale Ostro.

Scaling capacity made flexible and efficient

The new Nokia baseband plug-in cards drive the AirScale baseband capacity up to to 84 Gbps throughput and 90,000 simultaneously connected users. This is the capacity to drive 5G forward, towards more immersive user experiences and advanced enterprise use cases. Thanks to the latest technology the new cards are highly efficient and decouple traffic growth from power consumption. 

  • Leverage the modularity of AirScale baseband: new and earlier plug-in cards work together – ensuring latest SoC injection into installed base
  • Granular in-node composability: the right upgrade steps 
  • Common system (Single RAN) for 2G, 3G, 4G and 5G

Nokia Baseband System Module

Comprehensive baseband and far edge solution portfolio

We look at baseband processing from the real network perspective, which increasingly means looking not only at traditional baseband, but also at the edge of 5G networks. The AirFrame Open Edge server shares the same form factor as the AirScale System Module. It can run any far edge workloads, from virtualized RAN to O-RAN near-real-time RAN Intelligent Controller (RIC) to Multi-Access Edge-Computing (MEC), to the 5G Core User Plane Function (UPF). 

For outdoor and enterprise deployments the AirScale System Module is complemented by a very compact native outdoor baseband unit, which also enables smooth modernization of Nokia Flexi Multiradio installations.

AirScale site solutions cover all needs ranging from harsh outdoor conditions and unreliable power grids to lean distributed sites and powerful centralized RAN. Together with Nokia digital deploy services, AI-powered SON automation they ensure that AirScale baseband solutions are the ideal fit for all deployment scenarios and deliver efficient operation now and in the future.
