Mobile network operators (MNOs) continue to reap the windfall of the widespread adoption of smartphones. Mobile data volumes spiked initially and still rise quarter over quarter. Along with the demand for more data throughput from their subscribers, MNOs have to accommodate the greater need for responsiveness closer to the network edge.
While regular routers are good at serving Layer 3 services to mobile users on fiber-heavy backhaul networks, they do not do a very efficient job of servicing mobile backhaul networks that primarily use microwave radio. As it turns out, the worldwide majority of mobile backhaul networks are still based on microwave technology, as regularly updated industry research shows.
What can an MNO with microwave backhaul do to bring Layer 3 functionality to its customers that will handle bandwidth constraints, unique aspects of translating router protocols across the microwave interface and failure detection and recovery, among others?
Aviat Networks has published an article in Mobile World magazine that looks at these challenges of regular routers when used in a microwave backhaul network and proposes possible solutions.
