Quality of Service (QoS)

ePMP Supports 3 Priority Levels 1. Voice Priority (Always Highest when Enabled) 2. High Priority 3. Low Priority

• Unicast Traffic assigned to a priority level by L2/L3 packet markings • Broadcast/Multicast Traffic can be configured to be High or Low Priority • Data is scheduled for OTA Transmission according to its priority

Prioritization Can be Altered by SM Priority

SM Priority • Normal - No Change to Data Priority

• High - All non-Voice Ingress (Uplink) Traffic Treated as High Priority

• Low - All non-Voice Ingress (Uplink) Traffic Treated as Low Priority

L2 Markings: VLAN, CoS, EtherType, MAC / L3 Markings: IP, DSCP

The Importance of Spectral Efficiency

• Spectral Efficiency:

– A measure of how efficiently a wireless solution utilizes RF spectrum

– Defined as Throughput Achieved (bps) per Spectrum Utilized (Hz) – bps / Hz

• Clear Spectrum is a scarce resource

• A solution that makes efficient use of this scarce resource provides a superior Return on Investment to the Network Operator

• Example for Illustration: Four Sector AP Site with 6 km coverage radius deployed in 50 MHz of available spectrum:

#3

#1

#4

#2


Unsynchronized Deployment in 50 MHz

• No channel reuse with the cell

• Guard Bands between channels used must be greater than or equal to 2X then channel Bandwidth

• Avg Capacity of 5 MHz channel with 6 km range = 22 Mbps

• Spectral Efficiency of Unsynchronized Deployment:

4 x 22 Mbps = 88 Mbps / 50 Mhz = 1.8 bps/Hz
