Why does apple car play always drop in Dun Laoghaire

Cyrus

Always meant to ask, someone here will know im sure, is it something to do with the port maybe?

Always happens me too, along Crofton Road at the Dart station. Cuts out and back in at the exact same point.

Car Play itself is just software. The signal is via the mobile phone network, obviously, so it can only be due to bit of poor 4G or 5G coverage in that neck of the woods.

It is an older area, but there are cell towers on County Hall, so I don't know why it would suffer particularly.

The Port doesn't have any particular high energy transmission requirements, and even digital comms by the Harbour Master and Lifeboat aren't especially powerful.

It could be something to do with the DART power transmission system. There is some sort of transformer junction at DL station, so perhaps it is flooding the area with EM radiation that interrupts the local phone signal.

no car play disconnects completely, the connection to car play is bluetooth not mobile network afaik.

Ah I see what you mean. It must be the DART power system conflicting with the ISM band UHF of the bluetooth

Something similar perhaps, but the fob in my car never worked to unlock the car in the car spaces directly behind the Wooden Spoon in Blackrock!!

Again something interfering (DART??) with it just there!! Used to have to leave the car door open😁

I remember my wife having the same problem when driving over St Mary's Bridge in Drogheda. Her car at the time had a wireless Android Auto connection and it would always drop when going over the bridge, reverting back to the car's own UI. It would reconnect itself shortly afterwards. I'm not sure if it was Wi-Fi or Bluetooth. Her current car only supports wired connections so I don't know if it's still the case.

I drive daily past the harbour and never have any issues with Android Auto or older blue-tooth, 4g or 5G connections. It's not a localised issue and nothing to do with any transmission equipment in the area.

well something is causing peoples bluetooth to drop at the exact same place every time they pass.

I have that problem in exactly the same spot in Drogheda - and i've had it happen in 5 different cars - every time without fail.

Also some FM radio stations will get bad interference at the same spot RTE 1 and Newstalk

Three different android phones and three different car systems and I have never had this issue along the same stretch of road.

I find when going that way in Dun Laoghaire the signal cuts out even when listening to Radio Apps on the buses with the Wi-Fi working on the buses.

Multiple android and Apple phones and carplay and Android auto in multiple cars and I have had it and so have others judging by the thead.

I spoke to an electronic engineer acquaintance of mine since, and he said yes, that proximity to the source of power for a strong electromagnetic field, such as the DART overhead network can corrupt short-range Ultra High Frequencies, like the 2.4 GigaHertz that Bluetooth connections use.

As I understand it, these sub-station buildings at the western end of the platforms and adjoining the Crofton Wall wall are such a power source, and boost high voltage power into the network.

Not saying that it isn't, but if it was the AC to DC rectifier causing it then hypothetically we should also be seeing the same issues on the Luas network as they also use DC rectifiers.
