Bubbling Over
First it was your very own street light jammer. Now comes something that interferes with cell phone usage by jamming the frequencies it uses. I guess I'm behind the times, but I did not know there are such things as cell phone jammers. One model, the SH066PL2A/B, costs about $300USD and has a range of about 30 feet (~9m). There are others, including one that has a 100-ft (~30m) range. Now, before anyone calls their lawyer, I'm not advocating using one of these things because in the US they are apparently illegal. I'm just saying they exist. What you do with them are up to you. YMMV. Use at your own risk. Insert disclaimer here.
