Been troubleshooting a very strange problem for a couple of weeks now. I have a few hundred systems deployed throughout the United States utilizing EVDO connectivity with Verizon as a carrier. They are stationary. Over the past few weeks clusters of them in SF and Lewisville TX and a few other areas have been failing intermittently. They are offline for several days, then online for a few days then go offline again. They are running Linux and PPPD.
Do they maintain a continuous data link in normal operation (like, say, connectivity for a LAN, or backhaul for a camera or some such), or do they request the data link when they need to send [whatever] (like a discrete SCADA system)? My (user only) experience is that cellular data service doesn't handle long sessions well.
