This is a project to collate and document the types of tagging for telecommunication features. This range from submarine fibre optic cables through to mobile phone masts and towards data centres and telephone exchanges.
- 1 Long distance networks
- 2 Datacenters
- 3 Local loop networks
- 4 Radio networks
- 5 Local projects
- 6 Online
Long distance networks
Submarine cables, under the sea. Often from an import. See also OpenSeaMap.
- telecom:medium=* - fibre or copper

Datacenter regards facilities involved in telecom services production. Several sorts of them can be distinguished as below.
They usually are restricted access buildings with appropriate utilities supplies including power, fibre and eventually district cooling feeders to cool them down.
It is actually useful to separate buildings with compute or only traffic exchange capabilities as they're not located at the same level in networks.
As it's two really different functions, they're pretty always located at different places.
There's also a fair few buildings untagged, but with the name of data centre or data center in there. Most use the American spelling in the name. Following on from discussion about Community Centres - we will use data_center
telecom=data_center building=data_center name= operator=
Internet exchanges are physical infrastructures allowing private companies (such as CDNs for examples) to directly to an ISP instead of routing trafic over one or multiple ISPs.

This is not about computing at all however independent computing facilities may be located next to Internet exchanges
telecom=internet_exchange building=yes (if it is a standalone building) name= operator=
Points of presence
To be completed, wait for it
Local loop networks
These tags may be carefully replaced :
Telephone cables usually visible, black looking but often made from copper, and usually strung in the air from telephone poles. There appears to be three tags in use which refer to the same thing, sometimes these tags will be in combination with others.
Hardly any exist in OSM, but if they were to be mapped perhaps the following would be used
There appears to be at least four different tags for this, and they all point to the same telephone pole. The poles that carry telephone lines.
communication=pole telephone=pole ref=
(But see  for an entirely different approach.)
The often green, metal cabinets at the side of the street, on the pavement, used for a variety of things. There has been recent discussion about this on the mailing list
See Also the proposal for Telecom Local Loop https://wiki.openstreetmap.org/wiki/Proposed_features/Telecom_local_loop for more detail about the different street cabinets, DSLAM etc
There's a few ways that this appears in OSM.

Used in combination with :
such as CATV, BT, ref etc.

- Question about "operator(s)": Talk:WikiProject Telecoms
Small masts, sometimes attached to other structures.
Masts are the small standalone, usually single use antenna. Masts are generally held up by wires, or appear as a single pole rather than the free standing towers with supports. For telecoms these would be mobile phone masts in particular.
man_made=mast tower:type=communication communication:mobile_phone=yes|no ref= operator= height=
More than 60% of all man_made=mast have also tower:type. The alternative mast:type is almost not used and hasn’t a wiki page.
World Counts, overpass, 11 March 2015
4866 Global man_made=mast and tower:type=communication
and just in West Europe 4161 man_made=tower and tower:type=communication
Towers are larger than masts, are free standing and are not held up by wires

A man_made=communications_tower is the largest variety of telecoms tower. These are the ones that dominate the landscape, and have a number of antennas on them. They are often made from concrete and are usually a major landmark. An indication could be a height greater than 100 meters. Often they are accessed by internal lifts, rather than external stairs. Another difference is that a man_made=communications_tower has stairs and a lift inside, whereas as man_made=tower, has to be climbed on the outside.

Offices involved with telecommunications. Some may have data centres in them.

Local projects intend to document practices, knowledge and mapping guidelines relevent for a particular area in the world only. Feel free to create a dedicated one for your region if missing. Such page should only cover partiular area (like countries or region) but not a given infrastructure or facility for sake of consistency.
The project produces two map tilesets for Telecoms features: standard transparent markers and a "cloud x-ray" tileset showing a more artistic render with scaled polygons, overlapping markers and features shown at all zoom levels. In addition there is utf-grid tileset.
OpenInfraMap shows telecom lines, datacenters, exchanges and communications towers.
