A tiny article for OpenStreetMap State of the Map 2020
Cell towers, disguised or not, are vital communication infrastructure.
Let's put them on the map. As e.g., knowing where they are will enable us to know if we should climb mountain A vs. mountain B, to get a clear line of sight to one, during an emergency.
Launch app. On the signal strength page if the dB numbers are not extreme then switch to the SIM card (you've got a pocket full of them, right?) of the right carrier.
Walk in a circle around the suspected cell tower. The cell ID's antenna sector suffix should change once for each 120° etc. sector we pass through, and then finally back to the first when we reach 360°.
OK, now we have all the information we need to use the above tags to place it on the map!
Formats: e.g., 4G "106154015" corresponds to the human readable "414664-31". And after removing the sector suffix, and comparing that particular company(CHT)'s 3G cell IDs, "CHT 4664" would be a good Name for that cell tower. Additional details we have gleaned from the app could be used for Proposed_features/Telecommunications_tower.
Q: If public records are not available what about OpenCellID etc. projects?
A: those are mostly theoretical centers of cells, not physical tower locations.
