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
