I'm curious how this actually works. My workplace has extremely bad cell coverage and no GPS coverage indoors. I work at a satellite office about a mile from the main headquarters, but we have facilities (mostly small storefronts) over about a 1000mi radius from that location. Few employees have company-issued phones connected to the network. Whether or not we're connected (or have ever been connected) to the company network, people in my office will find that our detected location is maybe 200 mi away from our office, often in places that have none of the same ISPs as our headquarters and are nowhere near any of our facilities. The location will change maybe every few months. Currently we are showing up as being in the middle of a lake outside a town of 30000 people, though the FCC believes that area is only served by satellite internet providers. I assume our locations are being provided based on the MAC of the nearest router(s), but it's not clear why those router MACs get associated with such far-flung and uncorrelated places.
