Problems with Unsynchronized Wi Fi Solutions for
Outdoor Broadband Wireless Access
(1) Hidden Node Problem Causes “Collision Collapse”
One Solution:
• No Freq Reuse
• Large Guard Bands
between frequencies
(2) AP to AP Interference when some APs Tx while others Rx
• SM to SM Interference also can occur

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
#1 #2
#3 #4

Spectral Efficiency of Deployment Alternatives
1) No Synchronization
1)
2) Incomplete GPS Sync:
2)
– Inefficient Sync’ed MAC
– No Tx Pwr Control
– Poor Antenna F-B isolation
3)
3) ePMP GPS Sync

> 4X Spectral Efficiency
Copyright © 2013 Cambium Networks, Ltd. All rights reserved.
No Freq Reuse
Must have >= 2 x Channel BW Freq
Separation between Chans
Spectral Efficiency is:
4 x 80 mbps / (80 + 120) = 1.6 bps/Hz
No Freq Reuse
Must have >= 1 x Channel BW Freq
Separation between Chans
Throughput down to 50 Mbps
Spectral Efficiency is:
4 x 50 mbps / (80 + 60) = 1.4 bps/Hz
2 Channel Freq Reuse
Only 5 MHz Guard Bands between Adj
Sectors
Throughput supports 80 Mbps
Spectral Efficiency is:
4 x 80 mbps / (40 + 5) = 7.1 bps/Hz
14
The ROI of GPS Synchronization
•4X the Spectral Efficiency with ePMP, means
•4X the number of subscribers, which means
•4X the monthly revenue, which means
•Much Faster Payback with the ePMP
