Mobile Backhaul

The relentless demand for premium video services is putting a tremendous strain on network access infrastructures as service providers look to support the resulting backhaul traffic. Mobile video traffic exceeded 50 percent of mobile traffic in 2011 and the average mobile connection speed will surpass 1 Mbps in 2014.

As the cost of backhauling traffic continues to rise, the need to drive down costs continues to be the central focus of operators. The conversion to Ethernet-based IP-enabled packet network is inevitable due to the lower cost and higher scalability compared to legacy access solutions. Backhaul traffic can include data, management, control, clock synchronization, OAM and voice. Mobile backhaul consists of legacy SONET/SDH, TDM/PDH and next-generation Gigabit Ethernet services as 4G infrastructure is deployed by mobile network operators.


Delivering scalable reliability using Ethernet-enabled cell site gateways, next-generation, high density backhaul aggregation for both SONET/SDH and Ethernet and performance monitoring solutions.
Continue to support incumbent GSM, EV-DO or UMTS operations by reducing the cost of legacy TDM/PDH/ATM backhaul while enabling the evolution to IP/Ethernet backhaul for 4G readiness.
