Which quote from the FCC regs? The one that says "You must accept any interference" or the one that says "you may not cause any interference to a licensed service"
If you can show them a license, you might have them on the second one. Unfortunately, they have YOU on the first one. They may not even be subject to the 36dB rule anyway. Better to do what you can to avoid the interference using technology (frequency change, shielding, antenna polarity, more gain on your subscriber antennas - using a type certified antenna for your certified radios, of course. Otherwise in a p#$$ing contest with the USA's largest retailer, I think I know who would win. They have invested heavily in RFID and they and Home Depot have pretty much singlehandedly set the standard for requiring their suppliers to go to it. I know, because in an earlier life, I rolled out RFID for another very large company who is one of their biggest suppliers and this company (which has the world's most recognized trademark) JUMPS when Walmart says "jump"! The reason I emphasize "certified" is that when you do engage them, they have a lot better arsenal than you and you want to be squeaky clean. Where is the store in relation to your affected tower site?

Are they exceding 36db ERP? If they are exceding ERP and you can prove it by taking spectrum analyser out there have your lawyer send a certified letter to ADT and Walmart manager with this info and quotes from FCC rules and regulations. If there not exceding any limits you may SOL and your only option is to work around them. Sectorize your site. Matt > Hello List > We have an interference problem come up this week that we have been unable to resolve.Hopefully someone here has some input on how to resolve it.The problem is walmart installed a rfid scanning system at there loading dock which instantly raised the noise floor at our 900 mhz waverider access point by 20 db which killed about 30 of our weakest links.this equipment is operating across the whole band so there is no way to change channels and get away from it.The walmart store manager says its not his problem and refuses to call the company that installed it .I called the company which is adt security and they refuse to do anything unless walmart request it.walmart home office will not return my calls and the regional manager actually hung up on me and will not take calls from us now.We have been very polite with them upto this point and gave them no reason to act like jerks.Does anyone have any suggestions on how to resolve this problem? > Thanks > Ray Hill > surfmore. net > -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/ -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
