The performance of a WiMax network appears to be lower than expected and you suspect interference to be the cause. Write a 2 page letter to the FCC that requesting an investigation. The letter should include explanations of the following:
Test results you may have seen (spectral results taken at different points, packet transmit requests and logs)
Symptoms observed (when low throughput is observed, in what direction)
A logical argument as to why this would indicate interference.
A guess as to the type of interference causing the problem.
You are free to invent the details as you go.
