BridgeWave Adds QoS to its 80 GHz FlexPort Mobile Backhaul

BridgeWave Communications has added QoS capabilities to its FlexPort family of high-capacity 80 GHz radios for mobile backhaul. The gigabit backhaul solution now natively supports both legacy TDM traffic along with IP-based 4G traffic.

As more and more real-time applications appear on consumer mobile devices, carriers must ensure subscribers get the right application performance at the right time, even in times of network strain. Bridgewave said its FlexPort can now prioritize real-time application traffic to ensure these applications are given necessary network priority.

FlexPort does so by leveraging an integral five port Ethernet switch that applies Quality of Service rules to incoming traffic to prioritize data. FlexPort allows for up to eight queues for enhanced QoS performance and supports strict priority queuing or shaped deficit weighted round robin (SDWRR) queuing.

Another enhancement -- FlexPort now incorporates Ethernet Operation, Administration, and Maintenance (OAM) functionality. This facilitates automated end-to-end network management and monitoring that validates connections, detects faults and alarms, and monitors link performance.

In addition, Bridgewave is now support 1+1 configurations. This brings the same system redundancy found in traditional microwave systems to the millimeter wave spectrum with 1+1 Monitored Hot Standby (MHSB) configurations. FlexPort MHSB configurations allow for two outdoor units to be coupled to one antenna via the use of a millimeter wave MHSB Coupler, invented by BridgeWave.
