I would think it would require a faraday cage around the prison.
- TallGuyShort 9y agoBut it'll end up being an active jamming system sold by a sibling-in-law of the politician who proposes the measure that causes interference and other safety issues and is easily subverted instead.
- TremendousJudge 9y agoOr just tell the carriers not to accept connections coming from inside the prisons
- tlrobinson 9y agoCarriers can't pinpoint the location of calls (unless the phone provides the location, e.x. E911)
- rtkwe 9y agoHow? Carriers don't do active triangulation on ever phone within tower range so they don't know exactly where a connection is coming from.
- pbhjpbhj 9y agoSet up a base station in the prison, harvest the IMEIs, feed in to blocklist?
- rtkwe 9y agoAnd also block every guard/visitor/person walking nearby?
- pbhjpbhj 9y agoGuards and visitors could easily be whitelisted. Person's walking nearby the cells of a prison should only be guards/visitors or people whose phones you want to block?
- rtkwe 9y agoThe IMEI catcher's signal isn't going to stop dead on the edge of the prison/jail yard and a lot are near/in cities. Where I live the jail is right next to the performing arts center and the baseball stadium there'd be massive amounts of false positives.
- tlrobinson 9y agoWell, carefully constructed reinforced concrete could definitely act as a faraday cage.
