On June 8, 2009, the FCC posted on its website an interpretation (KDB 594280) of the Part 15

rules. This interpretation stated that neither end users nor professional installers can have access

to settings (such as region/country codes for frequency bands, DFS profiles, etc.) which could

allow a radio to be configured to operate in a manner other than that which was specified in the

FCC equipment authorization grant. Canopy Release 9.5 guards against operators inadvertently

selecting a non-FCC authorized configuration.

Canopy Release 9.5 also responds to FCC concerns expressed to the wireless broadband

industry about possible interference caused by Part 15 devices with TDWR systems. Note that

Section 15.5(b) of the FCC rules state that Part 15 devices are not permitted to cause harmful

interference.

Motorola Canopy equipment employs advanced radar detection algorithms which can

discriminate between actual radar signatures and other RF signals. This approach significantly

reduces false radar detections and the resultant service interruptions, giving operators using

Motorola Canopy equipment an advantage over competitors using equipment which only employs

less-sophisticated energy-detection-based approaches.

Although Motorola Canopy equipment is fully compliant with current FCC testing requirements,

these requirements may not adequately represent all TDWR profiles and it is possible that some

TDWR signals could go undetected. As noted in the Canopy DFS Deployment Guide

, Motorola

recommends procedures to help avoid any potential interference.

If new radios are received containing a release prior to 9.5, please follow the upgrade process as

described in Section 7.
