> Mobile phone providers have coverage maps that although not perfect, do
give some idea of coverage. For example, at my WV QTH neither T-Mobile nor
Verizon covers the area. But visitors using one or the other of those
carriers have had their devices work for a minute or two intermittently --
enough to alert them to a voicemail or to download some email. Then the
signal is gone again, usually for hours until suddenly their phone dings
again with a message or something. It's called "propagation." I'm not
sure of the mode.
It might be due to ducting. W7ZR had a place on the east coast of Baja
(XE2DV) on the Sea of Cortez where the cell coverage was very spotty but
he had a yagi pointing north to AZ and occasionally he'd have a connection
due to ducting over the water. I think the path eventually deteriorated and
I think having no internet access was one of the reasons he now lives in AZ.
Cheers,
