“Imagine you have three nodes talking to each other over wireless backhaul. If you pool resources, and if one [node] goes down, you can still leverage the other two,” Parallel Chief Technology Officer Rajesh Mishra says.
Mishra says the company’s founders set out to reimagine the radio access network (RAN) rather than just focus on different silos of the wireless industry.
Taking the big-picture pooling concept further, Parallel announced Tuesday that it’s partnering with PeerApp and Saguna Networks — two mobile edge computing (MEC) firms — to help wireless carriers manage mobile edge content delivery.
Parallel is using its Converged Wireless System (CWS) base station and HetNet Gateway orchestrator with its partners’ MEC technology. The CWS base stations connect to each other in a mesh fabric, while the HetNet Gateway aggregates all this backhaul capacity and makes it available for content delivery to eliminate backhaul bottlenecks with SDN policy-controlled dynamic content routing.
Parallel is betting that HetNets will be the most likely path to market for mobile edge computing as it addresses content delivery and backhaul challenges. The technology is currently being trialed, and more trials are being planned for the latter part of 2015.
Parallel’s CWS can improve backhaul conditions via two modes: License-assisted backhaul and unlicensed assist. In license-assisted mode, a HetNet Gateway might instruct the CWSs to offload video traffic over unlicensed spectrum while giving other types of traffic priority on the licensed spectrum. Unlicensed assist backhaul works on unlicensed spectrum and complements existing wired backhaul, providing resilience in a case of fixed-backhaul failure.
