QoS

The Diversity Access Point system utilizes five classes of QoS as defined by the IEEE 802.16e specification

» End-to-end QoS framework to meet the needs of true carrier-class deployments

» Service flows map services offered by the operator to end-users

» Each service flows associated with appropriate QoS parameters (e.g. scheduling class, DiffServ CodePoint (DSCP), minimum & maximum data rates)

» QoS parameters utilized at multiple points across the network toeffectively manage the end-to-end service

Five QoS classes supported:» Unsolicited Grant Service (UGS)» Real-time Polling Service (rtPS)» Extended Real-time Polling service (ertPS)» Non-real-time Polling Service (nrtPS)» Best Effort (BE)
