50Gbps PAM4 DSP for 5G fronthaul including O-RAN architectures

The AtlasOne chipset supports carriers which want front haul solutions that scale beyond 25G.

Carriers are upgrading radio capacity with wider bandwidths – up to 200 MHz – and massive MIMO technology with up to 64 transmit and receive antennas per Radio Unit (RU).

In order to realize these capacity gains, the corresponding fronthaul bandwidth needs to be concurrently increased to 50G.

O-RAN and vRAN architectures amplify AtlasOne advantages. O-RAN enables carriers to accelerate capacity upgrades by selecting the best-in-class radio and fronthaul solutions from different vendors as soon as the most advanced solutions become available.

With vRAN, baseband capacity instances can be aggregated in a Distributed Unit (DU) and dynamically shared among multiple RUs.

When sufficient radio and fronthaul bandwidths are provisioned, carriers can adaptively shift capacity towards unforeseen traffic spikes to improve network efficiency and user experience.
