Abstract
Methods may include alerting fixed service microwave operators that their network has been compromised due to interference, before their service is necessarily impacted. In an example, method may include receiving instructions to test fade margin for a wireless communication link associated with a receiver radio, wherein the wireless communication link is passing live traffic; testing the fade margin while the wireless communication link is passing the live traffic; receiving error information, wherein the error information is based on an error correction mechanism for the wireless communication link; based on the error information, determining that a threshold number of errors has been reached; and sending an alert based on the threshold number of errors.
Claims20
A method comprising:
- receiving instructions to test a fade margin for a wireless communication link associated with a receiver radio, wherein the wireless communication link is passing live traffic;
- testing the fade margin when the wireless communication link is passing the live traffic;
- receiving error information, wherein the error information is based on an error correction mechanism for the wireless communication link;
- based on the error information, determining that a threshold number of errors has been reached;
- determining a measured received signal level at the receiver radio when the threshold number of errors occurred;
- comparing the measured received signal level with an expected received signal level having a same error threshold as the measured received signal level;
- and
- sending an alert based on the threshold number of errors and an indication of a change in the measured received signal level based on the comparing.
A system comprising:
- one or more processors;
- and
- memory coupled with the one or more processors, the memory storing executable instructions that when executed by the one or more processors cause the one or more processors to effectuate operations comprising:
- receiving instructions to test a fade margin for a wireless communication link associated with a receiver radio, wherein the wireless communication link is passing live traffic;
- testing the fade margin when the wireless communication link is passing the live traffic;
- receiving error information, wherein the error information is based on an error correction mechanism for the wireless communication link;
- based on the error information, determining that a threshold number of errors has been reached;
- determining a measured received signal level at the receiver radio when the threshold number of errors occurred;
- comparing the measured received signal level with an expected received signal level having a same error threshold as the measured received signal level;
- and
- sending an alert based on the threshold number of errors and an indication of a change in the measured received signal level based on the comparing.
A non-transitory, computer readable storage medium storing computer executable instructions that when executed by a computing device cause said computing device to effectuate operations comprising:
- receiving instructions to test a fade margin for a wireless communication link associated with a receiver radio, wherein the wireless communication link is passing live traffic;
- testing the fade margin when the wireless communication link is passing the live traffic;
- receiving error information, wherein the error information is based on an error correction mechanism for the wireless communication link;
- based on the error information, determining that a threshold number of errors has been reached;
- determining a measured received signal level at the receiver radio when the threshold number of errors occurred;
- comparing the measured received signal level with an expected received signal level with a same error threshold as the measured received signal level;
- and
- sending an alert based on the threshold number of errors and an indication of a change in the measured received signal level based on the comparing.
