Gold Coast reception absolutely unusable on the train

@Lofauffeur74

Which Swisscom subscription do you have and does 5G work otherwise, e.g. normal in a train station?

In any case, there are already many places where there are objections, but along the SBB lines it should be relatively good.

N.B. I hadn’t been taking the train from Zurich HB to Zug for long and couldn’t detect any interruptions in the 4G and 5G network.

In the main train stations I have full display for 4G or 5G on the iPhone 12, so I’ll try to activate only 4G as a test.

According to the link below, there are very short interruptions, but the Swisscom network shows good coverage compared to the other providers.

You can also see that it switches from 5G to 4G very briefly because of my suggestion to try setting only 4G as a test.

For information purposes, the train drivers work with a tablet to receive the traffic information that is essential for smooth train operations, including in the tunnels.

If the GSM network were to fail, trains would run at reduced speeds due to a lack of safety. The same applies to the train crew, who checks the tickets with their smartphone without cellular data in a tunnel that cannot check the passengers.

I suspect your device has a cellular data issue.

It can also be quite possible if the iPhone 4G and 5G are set to automatic that the switching time from 5G to 4G is very delayed and that there is an interruption due to poor reception quality, or the iPhone itself has a problem because of this.

The creator of the thread mentions that it works normally in the train station, but the iPhone doesn’t have to switch here.

I found this under Zollikon!

I know many SBB routes, including this one. What kind of train are you taking? The Siemens S-Bahn trains? They are the very worst. Unfortunately, there are no repeaters on these trains, or special coated windows that allow mobile communications from outside to pass through are common today. But unfortunately there is nothing on these trains. The reception with this type of train is almost everywhere and constantly poor. If you are in a place where the coverage is relatively poor anyway, you will no longer have any network on the train. There are also a few places on the Gold Coast where the reception is not optimal, but otherwise it is usually relatively good. However, the coverage is also good in the tunnel, whether at Stadelhofen, Stettbach, etc. I can’t understand constant problems.

P.S. I’m sitting on the train right now, I’m in the tunnel from Stettbach to Stadelhofen 🙂 Reception 5G. Full bar display!!

@Lofauffeur74

No, 2G is no longer in operation. 5G and a commitment to trains, I am now a railway worker without revealing my job in this company.

In the case described, for proper 5G mobile reception, the public mobile phone provider (here Swisscom) must broadcast a 5G mobile signal in frequency band 28.

- In the railway tunnels via tunnel radio system by the railway infrastructure operator (here SBB).

https://de.wikipedia.org/wiki/Tunnelfunkanlage

- In Zollikon via the public mobile phone provider’s mobile phone antenna (preferably with a line of sight to the train tracks, for example from the other side of the lake).

[https://de.wikipedia.org/wiki/Reichbreite\_(Radio Technology)](https://de.wikipedia.org/wiki/Reichweit_(Radio Technology))

An in-train repeater that supports 5G in band 28 must be installed in train cars. Or the train car is equipped with car windows that are transparent to mobile radio.

If there is no proper 5G basic coverage in band 28 or the 5G support of the in-train repeater in band 28, 5G support should be switched off in the mobile phone settings. The use of 5G only makes sense anyway when Swisscom offers decent basic coverage with 5G standalone (SA) across the entire Mittelland via band 28. See:

Hi Lofauffeur74, unfortunately I don’t know anything about the coverage that would bring you any added value. However, I have a more general point that almost goes along the lines of a question…

Have you ever paid attention to where you are on the train?

This question probably sounds a bit stupid now, sorry about that…

However, it is the case that a cell phone cell can get a certain load due to the handover of the mobile devices, if a train is full and you are in the back of a train (without repeaters and other aids), so that you are purely from the In terms of send/receive power, it comes to the cell rather “later” than other users, this can have a rather negative effect….

You may have the opportunity to test this on your trip.

I would suggest trying with the car that is as front as possible and sometimes with the car that is as far back as possible…..

I’m looking forward to your feedback

Greeting

Chris

technical details on the topic of “handover”. If the intrain repeater is missing or the intrain repeater does not support the mobile phone frequency band currently used by the mobile phone, the mobile phone does not receive the mobile phone signal with the minimum required signal strength for a long time during handover in the overlap zone, which more often leads to failed handovers. Users can recognize failed handovers by the (temporary) termination of data transmission. Or in the case of voice telephony, when the telephone conversation is terminated.

If you need highly reliable voice telephony with the best voice quality without interruptions in a train car or road vehicle, you should use the pure 3G/UMTS mobile phone mode => mobile phone booked into the 3G/UMTS mobile phone network + “Mobile data” switched off.

Information on the minimum signal strength (more precisely: S/N) for reliable mobile reception can be found at:

The signal-to-noise ratio (S/N) and the number of free resource blocks assigned to the mobile phone for use are decisive for the speed of data transmission via the mobile phone network. See:

I travel on trains that are well to very well filled enough times that I can say that experience shows that the choice of train carriage (first or last carriage) has no significant influence on the speed of data transfer.

It may have an influence which train you use. From Baden, the S6 is the school train from 6:51 a.m. So from Regensdorf onwards (around 7:10 a.m.) it is no longer full to the brim, but is also overcrowded during school hours in the city of Zurich.

During school holidays it is just full to the brim.

Despite good 4G/5G coverage, there has been a gap in the Zurich-Dolder Grand, Degenried, Loorenkopf area for years. The advantage of this gap is that you are hardly disturbed by phone calls in the Degenried restaurant. When a US president stayed at the Dolder Grand, Swisscom set up a mobile antenna.

I often travel the St. Gallen - Zurich HB route later in the evening (when it’s dark). I have 5G all the time and I can use the ride to enjoy the SRF Tagesschau, ARD Tagesschau and SRF Aktuell without any interruptions on the tablet in the highest resolution (with good headphones, of course). Otherwise, I rarely use my cell phone on the train because I enjoy the view out of the window more during the day than the small screen, so good reception on trains isn’t usually that important to me. >I’ve never had any battery or reception problems with the printed book I took with me 🙂.

I have set all of my devices (Samsung) to 5G.

Very nice! 😂
