OFDM Backhaul Link Estimator Tool
The Canopy OFDM Backhaul Radios utilize a link budget tool that provides an estimate of the
performance and throughput of the link given the requirements and transmission conditions.
Motorola Canopy Backhaul Path Profiler
This Path Profiler is used to input the local and remote locations for a link. After submitting the values the
server will compute the land profile for input into the Link Estimator.

Motorola Canopy OFDM Backhaul Link Estimator
Link Estimator using the data generated from link profiler. It will be generated to estimate link
performance & throughput based on the data provided on the form.
The benefit of this link estimator tool is that you can optimize a link before deployment by changing input
data to see the effect on performance and throughput. For example, if a link calculation indicates low
throughput, then a number of inputs* can be changed to see the effect on improving link performance.
* Operating range and data throughput is dependent on multiple factors which include:
- Path Length
- Antenna height on local or remote site
- Obstructions (height and distance)
- Antenna type - Integrated or Connectorized (External antennas provide additional system gain)
- Connectorized Antenna Options (Dual or single pole Flat Panels from 1’ to 2’, Parabolic from 2’
to 6’)
- Location of the link – Site Elevation & Terrain
- Backhaul Radio: select 30/60 or 150/300 Mbps to determine performance impact
