Re: PtP vs. PtMP and max EIRP

LLigetfa, Industry Canada spectrum group do not expect irrefutable proof but they will also not act on mere suspicion.

They will accept even NetStumbler data if it is collected in a careful and methodical way and reasonably supports the illegal EIRP hypothesis. IC will do the rest with their fabulous CRC gizmos.

cmaenginsb, the "802.11 smarts" method to counter such WISPs can also be abused by hackers, so it is best not to discuss the details in public. They exploit standard 802.11 and various 802.11-derived MAC protocols and also the clear channel assessment (CCA) mechanisms in various 802.11 PHYs.

Such methods can be extended to "non-802.11 chipset" radios operating in 900Mhz and 5.8Ghz bands but only a few popular brand of equipment has been fully analyzed thus far.

Only once in my life, back in my teenage years dabbling with MATV, amateur, and CB radio did I ever lodge a complaint with what was then DOC (department of communications). It was over a leaking Ontario Hydro insulator and they drove out 60 miles to investigate it.

I have no intention of performing any sort of DoS against other WISPs regardless how uncooperative they are. In fact, I have no proof of any illegal EIRP, only the hearsay of others that might possibly be trying to get me off their scent. All I know is if I plug in some of the tower coords and specs into RM, some links report as not viable and if I ask for details, I get nothing.

For all I know they could be real nice folks lurking here on this board.
