Better destinguish between communication towers and mobile phone base stations

Tagging: communication:*=yes
Applies to: Node Area

Towers with any kind of communication are currently mapped as man_made=antenna, man_made=mast, man_made=communications_tower or simply man_made=tower together with tower_type=communication.


This page describes the tag communication:*=yes.

Let's see how to map a:

GSM base station
mobile phone on a roof communication:mobile_phone=yes Node A mobile phone base station (BTS) mounted on top of a house
GSM base station
mobile phone on a water tower man_made=water_tower
communication:mobile_phone=yes

GSM base station on a water tower
mobile phone on a chimney man_made=chimney
communication:mobile_phone=yes
Node Area A mobile phone base station (BTS) mounted to a chimney
GSM base station on a chimney


One of the aims is to have a difference in "important" and less important towers. On a good topographical map you want to show big transmitters on mountains or huge telecommunications towers in a big city due to being a great landmark, whereas less noticeable mobile phone base stations may be noise on a topographical map (although still immensely useful for things like wireless positioning). As you can see, a difference between base stations mounted on a tower or just mounted on a roof is made.


Advanced tagging of mobile phone base stations

You can add more information to the base stations, but remember: Only add information you know for sure. Please try to avoid the use of e.g. operator=T-Mobile, use MNC=01 instead.[1]

If you don't know anything about the base station, simply tag it with communication:mobile_phone=yes.

  1. Why not operator=T-Mobile? Because operator could already be used for the operator of the tower or the chimney!
