The Next-Step in Small-Cell Virtualisation

AirSymphony: A Stepping Stone to Future Network Evolution

AirSymphony is AirRAN’s Virtual eNodeB centralized processing platform that allows the creation of “Virtual” or “Cloud” LTE Radio Access Networks. AirSymphony works with any Airspan eNodeB, including AirVelocity, AirSynergy, AirHarmony and Air4G. Centralized AirSymphony platforms complement local Virtualized Clusters of Airspan eNodeBs, giving huge flexibility in the rollout of next generation architectures.

The Need for Small-Cell Virtulisation

With the proliferation of small cells in LTE, many operators quickly discover that traditional network planning cannot scale to support such a massive and rapid rollout. Connecting Airspan’s Small-Cell Controller (SCC) into the existing infrastructure of the operator, improves user experience and maximized network capacity also in extreme hyper dense femto deployments.

The Power of AirSymphony

Due to its unique design, AirSymphony can be deployed on a much wider variety of network architectures.

AirSymphony is used as a centralised manager, it configures and optimizes each of the small cells within its region, improving user experience. Maximizing network capacity and simplifying management and configuration.

Key Features


Supporting Downlink and Uplink CoMP to eliminate interference and minimize handovers within a small-cell cluster.

Inter Layer dICIC

Negotiates resource partition (ABS) with the macro cell on behalf of a cluster of small-cells in order to optimize cluster performance.

S1 Aggregation

It terminates all small cell S1 connections and proxies them as a single connection to the MME.

Enhanced MIMO schemes

Combines different small-cells to create a 4×4 MIMO transmission or even higher MIMO schemes towards a single UE in the network.

Hybrid SON

Complements distributed SON architecture with a centralized SON function, providing a Hybrid SON architecture that optimizes Airspan Virtual eNodeB clusters even further.

X2 Aggregation

Aggregates X2 interfaces from individual small cells, and presents a single X2 for the entire E-SCN (Enterprise Small Cell Network) to each macro eNB.
