Troubleshooting Areas
There are five key areas to be aware of when troubleshooting.
Network Integrity: Continued performance and reliability of a network depends upon maintaining the
integrity of the network. If you change a network’s design, you will affect its operation. Be aware of recent
changes to your network.

changes to your network.
Quality of RF link: Data communication depends first on the quality of the RF link. If you can establish and
maintain a high-quality RF link, then you can be sure the link will carry high-speed data. If the quality of the RF
link is degraded for some reason, the quality of the transmitted data will also degrade.

Radio Hardware:There are three basic parts to a AWE: radio unit, antenna feed (cable, connectors, surge
suppressors, patch cables etc.) and antenna. You can isolate faulty hardware using measurement and/or
replacement methods.

Verify the radio unit with diagnostic tests (such as RSSI and link monitor tests), bench test a unit, or
replace a unit.

Verify the antenna feed with a Site Master test set. Sweep cables, connectors and lightning suppressors,
or exchange these parts for known good parts.

Correct Unit Configuration: Units must be configured correctly, according to the network plan.
Configuration errors can cause an inability to communicate or poor performance. The addition of units or
changes to your system may require you to change configuration settings.
