Monday night I am sponsoring a picnic for the local ham radio club. One of
the members works for the WAN company (ISP) and is bringing his mobile 2.4
GHz Wide Area Network setup in his pickup truck to demonstrate 500MB/Sec WWW
interconnect from the vehicle.
This WAN is operating in southern Minnesota. It is apparently the largest
RF based WAN in the world. It goes from Central MN to the IA border (about
125 miles square--just a guess). This company has been suspected of causing
unusual noises on the bands, including lots of falsing of repeaters near
nodes (nodes are located on a 5-7 mile grid throughout the area). It is an
ethernet based structure. A technician for the company has admitted that
some of the equipment does not (and may not) meet FCC rules but I couldn't
get him to elaborate as to how.
They don't know it but while they are demonstrating their blazing fast
transfer rates right on my property, I am going to be in the shack taking
notes off the screen of my spectrum analyser and radios (HF, VHF,
UHF)--located only 150 feet from the demonstration.
What tests should I (can I) perform to identify possible noise signatures
eminating from their equipment? Your thoughts would be greatly appreciated.
