BreezeMAX Extreme 6 System Manual
The BreezeMAX Extreme supports the following Capacity and Distance
Enhancement methods:
» MIMO Matrix B in DL direction
» MRC (Maximum Receive Combine) beam forming algorithm in UL direction
» Automatic rate adaptation to provide the optimal air link capacity in UL
and DL direction for each user.
» Open and close loop power control to prevent weak CPEs of neighbor sector
from being interfered.
 Enhanced Scheduler Functionality
.
The Bree
zeMAX Extreme provides the optimal service using a Scheduler to
allow the best performance, throughput and quality service. The Scheduler
offers the following capabilities configured seperatelly for UL and DL
directions:
» Configurable MIR and CIR
» Three traffic strict priority levels: 0,1,2
» COS supported are BE and nRT: BE uses only one priority: 0; nRT uses 2
priorities: 1,2
» BE non-starvation is provided by a minimum internal CIR of 14Kbps
» Lated packets drop mechanism
» BE drop latency is 300ms
» nRT drop latency is 200ms and 100ms considering selected priority levels
1 or 2 respectively.
» Unsoliciatated Polling mechanism for nRT based on half of latency time.
 Mobility is based on fast network entry mechanism.
