    What's weird is when you are actually receiving a strong signal on a mountain with clear LOS & still can't make a call. I'm assuming the handset lacks sufficient transmit power to talk back to the cell?

    I ran into that at the Grand Canyon. Perfect signal but was unusable. This was back in late 2008 though

    If you're on the top floor, rooftop HVAC equipment can badly interfere with reception in older buildings. It's a serious problem in GSA buildings in my experience.

    At the rim or below? At the rim, VZW's one tower there could be overloaded. Below: that or you're seeing an edge-defracted downlink with no clear uplink path.

    Was at the rim. Also this was 2008 before LTE. No clue what I was roaming on. I didn't have Verizon back then. I had uscellular. If Verizon was the only tower there then it might of been Verizon.

    Funny part is I had better overall service than my grandparents who had Verizon while traveling out west. I guess uscellular had more overall roaming partners than Verizon did oddly. Granted a lot of the roaming where I could roam and they couldn't was voice and text only.

    Commnet Wireless. Verizon's site there seems to have powered up in 2017. I could be wrong about that.

    80 stories is a made up #

    most office buildings that i have been in manhattan are less than 80 stories and have DAS systems

    also, i have found that you might connect to one cell tower at one floor/location in a building and then another at a different usually higher floor/location of a building.

    I've also seen that due to license boundaries; used to be here, you'd have the digital signal drop off right at the county line (seriously, within a foot or two of the county line sign, it was pretty accurate), the service would drop with 3 or 4 bars and switch to extended network. The license ended at the county line, the cell site's sectors can know distance between site and phone with the timing advance info, and sectors pointing out of the license can then be set to cut off service at a specific distance, while ones pointing into the license aren't distance limited.
