That's right...ass. Why? Because that's where inmates cram 'em. So it looks like the Bloodhound here will be pointing directly the backside of a lot of prison jumpsuits.

In all seriousness though, contraband cellphones are becoming a major problem in prisons throughout the country. One solution, cellphone signal jamming, has already been passed by the Senate. Bloodhound is intended to be an alternative to jamming—a device that sniffs out cellphone RF signals using a high speed scanning multi-band receiver harnessed to a DF-Direction Finding Antenna.

The problem with all of this is that prison guards would each need a detector, and they could only get results when the cellphones are actually in use. So, it seems like the best solution is still jamming cellphones en masse. In that scenario, the FCC would be required to lay out rules and ensure that legitimate communications are not blocked, which negates Bloodhound's one major advantage.
