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

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:

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
