New tag: Mobile coverage / connectivity

[killakalle]

I would like to request new tags to describes a crag's mobile coverage or mobile speed, e.g.

• Good connectivity
• Medium connectivity
• Low or no connectivity

There are several situations where this information would be helpful

• Climbers with professions where they can be "on call", e.g. doctors, system admins, etc., want to know whether they'll be reachable by phone
• Before visiting a new crag, it's helpful to know whether crag information can be accessed on the fly or whether it should be downloaded upfront
• ...possibly more...

Before implementing anything, I strongly recommend to do a survey amonst all thecrag users (not only those few that also are github users) whether information about mobile connectivity is desired at all, because it is much more controversial and emotional than you could expect from such a short information. Background on that (optional reading - TR;DR is fine): A few times, I added infos about mobile coverage to crag descriptions and some users sharply complained because mobile coverage is (from their point of view) against the spirt of climbing guides, mobile coverage must generally be expected to not exist outdoors, if one does not want to climb without mobile coverage one shall strongly question whether one goes climbing at all, it's not relevant but spam. Others see the information as very relevant in a climbing guide, e.g. when having the choice to either not climb at all xor to pick a spot with mobile coverage. Personally, I've the impression the info on mobile connectivity is not in itself so controversal, but what it stands for: The freedom to go climbing while respecting obligations vs no "real outdoor" left, modern/digital versus traditional mindset.

Some thoughts about implementation

• Make the information inheritable, so in regions with ubiquitous mobile coverage, the tag may be maintained only once on region level (reduces maintenance work).
• Distinguish between pure telephony and internet connectivity? That may be relevant if you need e.g. messengers like signal/whatsapp/... or e-mails or IP-telephony for your obligation / use case.
• For internet, distinguish between 2G and 3G/4G/5G? EDGE versus LTE makes the difference between you can do remote desktop or not
• For 2G and 3G/4G/5G, the signal strength or reliability? If 3G/4G/5G is weak/shaky, you may be able to get messenger texts but not to do remote desktop.
• Distinguish connectivity of different mobile networks? National roaming between different carriers is unusual e.g. in Germany.

If we'd like all of this, tags are IMHO not suitable but two drop downs:

• Country. Serves as filter for 2nd drop down, e.g. 2nd drop down shows only a hand full instead of hundrets of choices. Is required for crags nearby borders having mobile networks of multiple countries.
• Network, speed and reliability.

For one region/area/crag, users could add unlimited number of entries. Example for a crag near Lake of Constance:

• Switzerland: Swisscom 3G/4G/5G strong
• Germany: Vodafone 2G strong, Vodafone 3G/4G/5G none, O2 3G/4G/5G medium
• Austria: Magenta 3G/4G/5G medium
