Some places are using an experimental technology of managed communications that blocks the communications of inmates while continuing to allow that of others. This Managed Access System (MAS) technology was first deployed at Mississippi State Penitentiary in 2010 by Tecore Networks. Special dogs have been used to sniff for cell phones coming into prison walls. Mobile phones have a unique scent, and these dogs have been trained to detect it. One solution would be to enable the correctional facility to automatically detect and locate contraband 2G/3G/4G and WiFi mobile devices thereby enabling the facility staff to confiscate the phone and neutralize the threat completely. An automatic 24/7 detect and locate solution such as this bypasses the weaknesses inherent to jamming (e.g., phones of facility workers can be jammed);
