Even the PR people from Telia and Ericsson (who are partnering to do this again, just like how they launched "the world's first 4G network in Stockholm in 2009") say (when interviewed by Swedish media) that this will be similar to the 4G preview/test. So what we can expect to see is city-wide coverage and a few thousand heavily subsidised end-user 5g terminals (probably USB 3.0 modems at first - at the 4G preview in 2009 they came from Huawei.) Making Stockholm/Tallinn-wide coverage a reality with that few users isn't super costly. Ericsson are happy because they get a realistic field test of usage, handover between base stations etc. They also get a credible proof of concept for further sales. Telia are happy because they get to project the apparance that they are ahead of the curve to their customer base. Telia and Ericsson have had this symbiosis thing going on for 100+ years now, btw. It seems to be working quite well for them both.
