Most commercial deployments based around emerging open RAN architectures are in small cell networks, which are often in greenfield environments and can be deployed at limited scale, at far lower risk than a main macro network.
These early roll-outs will provide valuable lessons about how open architectures work in practice and how they compare, in performance terms, with traditional networks. At the Telecom Infra Project Summit in London this autumn, Parallel Wireless gained a significant profile boost when it was selected as one of the vendors which best met the scope of an RFI (request for information) from the TIP’s OpenRAN project group. The aim of the process was to identify and highlight suppliers which might be well positioned to execute on the vision of an open, disaggregated, virtualized mobile network in future. Vodafone and Telefónica both issued their own RFIs, based on the TIP OpenRAN one.
Parallel was recognized in five of the seven categories, as seen here:
- For most compliant end-to-end platform: Mavenir; Parallel Wireless; Altiostar.
- For 2G software: Fairwaves; Parallel Wireless.
- For 3G software: Mavenir; Parallel Wireless.
- For 4G software: Altiostar; Parallel Wireless; Radisys.
- For Remote radio head/ radio hardware: Baicells; NEC; Parallel Wireless.
- Innovators: ASOCS; Phluido.
- Challengers: Comba; Dali; Fairwaves; Vanu.
Now, Parallel has been selected by US regional operator Cellcom to supply its Open RAN solution in the US Midwest. Cellcom said it would add the vendor to its portfolio to enhance service in its existing footprint in Wisconsin and Michigan, and for an initial, non-commercial deployment in a new area.
