Airspan Networks, a leading provider of 4G LTE broadband wireless access networks, unveils Software Define Networking (SDN) based Small Cell Backhaul solution for aggregating multiple backhaul technologies in a single network.
Airspan’s iBridge Small Cell Backhaul solution combines operation in licensed and unlicensed spectrum using LTE Relay or PTMP NLOS technology in licensed bands and 802.11ac operating in the 5 GHz band. At the heart of this solution is Airspan’s SDN architecture for Small Cell Backhaul networks. This architecture combines available backhaul routes and schedules LTE small cell traffic over individual routes according to their QoS and bandwidth requirements. For example, signaling and high priority user plane traffic is routed over licensed spectrum, whilst lower priority traffic is offloaded onto less robust 5 GHz unlicensed or low cost wireline connections such as Bonded DSL, VDSL, DOCSIS, or PON.
“Paul Senior, CTO of Airspan Networks commented, “By aggregating available backhaul connections according to QoS rules, a small cell backhaul network can robustly deliver capacities in excess of a Gigabit per second. NLOS wireless backhaul, or LTE Relay, provides the means to roll out small cells quickly and cost effectively.”
