Cellmapper rogue transmitter

Any Cellmapper experts around?

I've been collecting data from our surrounding area for both Vodafone and EE SIMs, and I've a very strange picture for EE in that as far as Cellmapper is concerned, there is an EE LTE transmitter right on top of our house (there definitely isn't!). It's marked as eNB ID 31533, and it tells me it's been seen today, as it does every day I switch on my phone with the EE SIM in it and run cellmapper.

The phone isn't the most up to date but it's on the cellmapper list of "phones tested" and supports the Android API required for best results. It's a Sony Z5 Compact running Android 7.1.1

Can I just delete the transmitter form Cellmapper? That seems a bit harsh if it actually does exist somewhere nearby, but I've done dozens of test runs around the house hoping that it will eventually cop on and disappear from the results, but it just keeps appearing.

Thanks for any insights!

Cheers

The red icon means this is a "computed" location, based on measurements. A green icon is a location that has been positioned by a human.

You may need to go further afield, the transmitter coverage is all in one direction, which is very unlikely as masts will typically have 3 sectors, especially in rural areas. Some will have 1 or 2, but those are less common.

If you think you know where the EE mast is, you could drag it. If you don't have any idea, then I suggest leaving it?

Your handset is great, as it appears this mast has a LOT of connectivity with Band 20, Band 3, and Band 7, so for those lucky people close by there should be a lot of performance.

Is it a 3G transmitter only?

Some people have the EE signal boxes, either supplied for the current address and/or they get them at one address, move and plug it in again at the new place. It could be this, Vodafone have a similar device they issue to customers, and 3 (who rarely issue it) have one also. Nowadays they recommend WiFi calling, if a user says this is dropping a lot, and EE can see this to be the case, they will issue a signal box. They're not very useful if you have marginal 4G, as your device sticks on it even though 3G is full.

Nope, its LTE, not UMTS, and providing three bands.

I have noticed the same. There is one near my house which definitely isn't a mast.

Thanks, also just zoomed out and can see it suggests there is a second coverage area south of the Tay estuary as well as local to us on the North side, and 6 different Cells. Seems to imply the mast is perhaps around the middle, either in Tayport on the northern edge of the southern side, or Broughty Ferry, on the southern edge of the Northern side.

Is that a reasonable assumption to target my future tours of mobile transmitters? Might need to get in my boat to do full circle!

Cheers again

Ha, I'd not zoomed out enough. Yes, that implies perhaps you are picking up quite a distant mast, from one of those built up areas, and there isn't enough data elsewhere to help the location predictor.

A boat tour sounds like an idea for a warmer month, but maybe just walking around some of the estuary would provide sufficient data on signal strengths. Depends if your aim is to find the actual transmitter, or just move the dot

Hill top above Tayport.

Thanks Paul, I see you've exerted your influence and it's now showing me the right story. A small part of me wishes the transmitter was in our garden, but hey ho...
