I don't know if you noticed this but in my area most of retail stores have terrible cellphone reception. I'm assuming they put cell jammers in their store too

- colinbartlett 13y agoThat's a pretty unsubstantiated assumption. Could it simply be that cell signals have trouble penetrating the store walls?
- mahart 13y agoThere are building materials that naturally block/reflect/absorb mobile frequencies which is perfectly legal. That is different from transmitting a signal to jam which is highly illegal.
- dingaling 13y agoOne other trick is to advertise as a cell and accept connections, then just black-hole them. Full signal strength but no calls. Edit: may be illegal in your jurisdiction if you require a license to transmit on cell frequencies.
- thisone 13y agoI think it might be the fact that it's a rather large concrete box with very few areas that signal can pass through.
