Thanks Brian. I am very familiar with how it all came down (and I know who you are following!) and with you being an actual participant and not just a witness I appreciate you sharing the 'inside' information that reinforces the overall message: this is serious business and no playing around with illegal gear is going to be tolerated.
I'm suppose I've been coming down very hard on the topic because I'm trying to influence quick change about an entrenched attitude among many WISPs. I am deeply afraid for the WISP industry if this band is treated as cavalierly as so many have treated 5.8 GHz with respect to the rules. What really has me worried is that 5.25-5.35 GHz is already a band where lots of abuse occurs and this band gets fully rolled into the 5.4 rules come July. Having sat on the panel yourself, do you think I am over-stating the seriousness of this?

The FCC is forced into this because of the DOD (Department of Defense). We had a difficult time keeping the DOD happy due to the nature of the highly classified radar patterns. The FCC will not allow ANY TCB (Telecommunications Certifications Body) to certify the 5.470 to 5.725GHz for a year or until they become comfortable with a specific TCB. The testing requires a $250,000 investment in equipment with 180 separate test covering 30 different wave forms. The only testing lab I know of is Elliott Labs http://www.elliottlabs.com in Fremont California that has the required test equipment. After they complete the test then the radios are shipped to Washington DC where the FCC will perform the same test all over again to compare the results. This whole process takes about 3 months if you are lucky. I'm following 2 in process currently. Regards, Brian E. Magnuson President Cascade Networks, Inc.

There are also a good number of international firms available for public contract to perform FCC certification tests. However, I've learned that for the purposes of 5.4 GHz compliance the only lab that will be able to certify systems is the FCC lab itself in Maryland. While I do not know if this is something that may change over time, the clear message it should send to us all is that the FCC is taking 5.4 GHz compliance extremely seriously. This is all about the strict DFS mechanism designed to keep UL 5.23-5.35 and 5.47-5.725 GHz systems deployed in the U.S. from interfering with the secret military radars. (If any are wondering why also 5.25-5.35 GHz, it's because the grandfathering for current systems ends firmly on July 20 this year.). Accordingly, all WISPs, even the least inclined to follow the rules to the letter, are thus well-advised not to equivocate on 5.4 GHz. >From Alvarion's side, we usually use one of the many authorized contract firms in California and the process to gain legal system certification has historically been routine and not especially onerous. On this one though, the testing is so tricky and in-depth (expected to drill deep into the hard coding to make sure no 'creative' aftermarket coding can occur), that we are already processing visas for a team of our programmers to supplement our domestic product management folks just for the purposes of this certification.
