Backhaul Evolution
Backhaul: Once the “after thought” of the wireless infrastructure
Explosive growth in recent years
4G & LTE are pushing the limits of existing networks
Today’s MW solutions are more powerful and cost effective than ever
Gigabit & Beyond now possible
Wireless Backhaul is essential to today’s network!
Wireless Backhaul Markets & Applications

PTP Applications
Licensed bands vs. Unlicensed bands
Licensed
Advantages
• No risk of interference
• Higher capacity
• FDD
• Lower Latency (<1mS)
• Product Reliability
• Network Reliability
Disadvantages
• Licensing fee
• Time waiting for license
• Typically more expensive
Unlicensed
Advantages
• No license required
• Quicker deployment
• Typically lower cost
Disadvantages
• High risk of interference
• Typically lower bandwidth
• Typically FDD
• High latency
• Interference causes poor
reliability

Conditional certification: User may be required to change out antenna if it causes interference.
Smaller antennas may be allowed in coordination.
*Higher throughput figure represents max throughput for small packets due to header compression

Analysis against existing
and proposed stations
(other microwave,
satellite, TV relay, etc.) to
ensure no interference or
performance impact.
Confirm performance
matches FCC
requirements.
Coordination per path.

FCC Licensing
Form 601
Double and triple check coordinates, line of site and
Fresnel zone for path obstructions
If no issues, submit to FCC
Coordinator notifies other licensees in the area for
comment.
Approx. 30 days for notice to be reviewed by licensees.
Pay filing fees to FCC per site.
$470 for new, $270 modification
No fee for gov agencies
