    hahah these are already in place and in use. they already have cell blockers in many places. this is not new and the fcc knows all about it.

    the ‘new’ hotness is a pico cell that allows for voice/sms but no data

      Yea, no. The FCC is quite explicit on this, read for yourself:

      The use of a phone jammer, GPS blocker, or other signal jamming device designed to intentionally block, jam, or interfere with authorized radio communications is a violation of federal law. There are no exemptions for use within a business, classroom, residence, or vehicle. Local law enforcement agencies do not have independent authority to use jamming equipment; in certain limited exceptions use by Federal law enforcement agencies is authorized in accordance with applicable statutes.

        cool, every school in my district has zero cell signal the moment you walk in the building. it sure as hell aint the architecture

        im going to investigate… they are using something

            i just asked my kids, they confirmed that the schools actually ‘turned it on and off for specific areas of the building as needed’

              Sounds like illegal jamming to me, def collect some evidence if you can and please report them. I bet they have them mounted on/near the ceiling. Maybe a phone with a good zoom could capture some good evidence pics

                i hate this place. i walked into the front office once and they took my picture as part of some security nonsense, so i took my phone out and took their picture. they got super-pissed at their sudden lack of privacy

          If it is in fact the moment you walk in the door, then it absolutely is the architecture. If the architecture didn’t have any effect on it, whatever’s disrupting the signal would also interfere with the signal outside.

          Damn near every school building I’ve ever been in is a behemoth of brick, concrete, and cinder blocks. Cellular and other radio signals have a hard time penetrating that.

          Same for a lot of hospitals, big retail stores, and other similar places.

          I work in 911 dispatch, we have caution notes attached to the addresses of a lot of schools, hospitals, various office buildings, etc. in our area that there’s poor cell reception or that our responders can’t get radio reception inside the buildings, so we know how we can or can’t communicate with our units when they’re responding to an emergency there. I can guarantee you those places aren’t purposely jamming police radios.

          I lose my cell signal in parts of several of my local grocery stores, big box retailers, etc. that’s just part of being inside of a big concrete and metal box. Why would they even want to interfere with my ability to use my phone?

          A lot of these buildings were built before cell phones were even a thing, so reception was not a concern in their design. Even in newer buildings, it’s often not a major consideration.

          And as others said, jamming a cell signal is a huge no-no from the FCC. If anything, and I doubt they’re even doing this much, they have picocells (basically tiny cell towers) in the building that they’re turning off at certain times. If they didn’t have them, there would still be no signal in those parts of the building.
