Outdoor OpenRAN

The need for providing both coverage and capacity and supporting growing data consumption, all with declining ARPUs, have placed tremendous pressure on MNOs to find the most efficient use of their allocated radio spectrum.

Our outdoor OpenRAN helps with spectrum optimization to make MNOs profitable The architecture consists of:

Virtualized Baseband Unit (vBBU)

Based on Intel-based COTS (x86) hardware, this component provides High-PHY, MAC, RLC and PDCP functionality in a central fashion. It communicates to a cluster of RRHs (which contains RF and lower PHY) and supports multiple carriers based on the RRH cluster’s load. The interface between vRU and RRH is based on Ethernet-based eCPRI. This architecture supports 4G today and is software-upgradable to 5G.

Remote radio heads (RRH)

The Parallel Wireless solution incorporates standard, off-the-shelf RRHs and small cells from different OEMs. These OpenRAN RRHs and small cells can be integrated into our solution with minimum integration effort, reducing the overall cost of ownership for mobile operators.

Parallel Wireless has developed extensive OpenRAN partnerships to support all use cases for coverage and capacity:
