Such types of law enforcement personnel who benefit greatly from the deployment of any state in the art portable RF jamming solutions,who can conduct the law enforcement process more effectively to reduce the chance that the criminals leak the information.
Mobile phones were seized from Block 1,2,3,4 and High-Security block 1. A cell phone jammer had been installed in the prison premises two months back. Last year, there were allegedly 72 mobile phone cases registered, while the number is already at 64 this year.
That would mean every smuggled phone in the facility would be quickly identified. In addition, it would be relatively easy to create a list of permitted phones (owned by guards, office staff etc) and pass calls from those devices through to the communications networks. Alternately, we would have to ask exactly why it was that a guard needed a phone while on duty.
Even better, this method would permit the identification of those being called from the gaol, especially if the existence of the base station was kept very quiet.
Gullas added that purchasing a signal jammer device is an additional expense of the city with funds that can be utilized for other purposes.
