  Walmart either uses building materials that impede the signal or actively block it. I also can never get full 5G inside a Walmart, and sometimes I wonder if they are doing it on purpose to encourage using their local wifi.

    I’d imagine that’s part of it. But it’s also a big metal building, farady cage and all.

    Walmarts are big windowless boxes.

    5G Ultra Wideband uses millimeter-wave frequencies, which are fast if they have a clear line to the tower…but don’t penetrate material well.

    On the challenging side of the equation, millimeter waves don’t propagate as far as low-band or mid-band signals, so there is a much smaller target area used to receive a signal, compared with sub-6 GHz signals. In addition, millimeter wave signals are subject to more diffused scattering when in contact with large objects, and they receive higher signal loss from foliage, object penetration, and from the atmosphere. This means you have to put a lot more millimeter wave signal repeaters around, so you get good mmWave coverage.

    I get it bad in any large store, mainly because its a very large metal box. Its basically a faraday cage.

    Nope. I know they do that. This was taken in the parking lot. I am starting to suspect there is something on the roof that is disrupting good cell signal.

      Or maybe the service is degraded because there are thousands of people connecting to the same cell and Verizon can’t justify the $$$ of placing more transceivers/bandwidth in a supermarket placed in the middle of nowhere with zero residents.

      I don’t think Walmart is willing to pay millions in fines from the FCC by installing a 5g jammer because reasons

        You make a couple of good points, however you may want to double check your knowledge of Eastern Massachusetts population densities. I also don’t think Walmart gives two shits about paltry FCC fines, because forcing you into their wifi where you are required to agree to a ridiculous amount of data sharing, is certainly a lucrative proposition for them.

      That would be highly illegal on a federal level.
