Wait for it...

So every once in a while, I travel this route west out of Helsinki for work-related errands on the motorway. The first thing you encounter is a bridge to the nearest island (Lauttasaari, for instance).

Here it comes:

no matter when, during any day, I travel through Lauttassaari, in either direction, my Jolla C ALWAYS has a generic LTE connectivity hick-up in this specific spot; sometimes even twice (one when entering Lauttasaari and one when exiting). This has been the case since day 1. I wonder, is this a "bermuda island" of Finland?

Perhaps an important base station was lost when they demolished the Lauttasaari water tower...

Which cellular operator are you using? Have you tried any other phones (or other operators' SIMs on your Jolla) - can they keep the connection at Lauttasaari?

Might be operator related thing?

And as OT joke: No the bermuda triangle of Finland is the area limited between Turku, Rauma and Eura but it has nothing to do with disappearing/weird stuff other than just people speaking funny dialect no-one can understand outside of that area.

In my experience DNA is the only operator that has reasonable coverage on Lauttasaari

Im on sonera. This did not use to happen with the OTH (which I had in use before last june, when I got my jolla c, with the same sim card) when travelling the same route. If they have "demolished" a tower or two, it'd be noticed also before I'd assume, as the constructions have started waay before June - and probably will last for much longer, pun for you länsimetro!) And yes, the connection on Lauttassaari is ok, it just has the hickups to / from it (like when changing base station?)

EDIT: After the misunderstanding over which bridge was meant, I can indeed confirm that all network coverage including 3G is lost for approx 1sec on the bridge. How trippy.

OLD: I tried to replicate the problem by driving over the bridge a few times without any luck. Made a point to drive slowly, to much annoyance of my fellow drivers. Specs: Aqua Fish, Fiskarsinjoki 2.0.4.14. operator DNA

So there are two possible scenarios:

  1. it's a problem with your operator, shame on Sonera.

  2. You are the chosen one and you have entered the matrix.

For 1., I had the same sim card in the OTH (up to june), but not the same issue. For 2., I have exited the matrix a long time ago :)

Wait a moment - which bridge to Lauttasaari did you cross? Länsyväylä or the Lauttassaari one (and yes they need to be differentiated, even tho they are both bridges and lead to the - almost - same place). Im talking about the Länsyväylä one.

No the one to Ruoholahti :D

So now that we have two cases; what can Jolla do to fix this / what can we-I do?

Other than sending logs, I mean.

There's nothing you/we/they/anybody can do, except for Sonera.

They should for starters try to define the network so that physically adjacent areas are marked as handover points in their network map. Their cell grouping is really badly planned.

but I have the same issue with DNA. Is it possible/probable that two operators with different cell networks would have the same blind spot?

Very good point! @fstrahlm, and if I understood correctly, your sfos is different from mines (2.0.5.6)? Ball's on your side, @juiceme!!
