Wow! How do you determine the true location for looking at the cellmapper data?


I've just walked upto Audley House. The signal wasn't great on the approach. When we used Three we had good signals in that area. Cellmapper says there is a Three site at the same location. I thought Voda/O2 shared sites but wasn't aware of Three/EE.

There was an old noticeboard with T-Mobile 91922 Audley House, so it is an EE site. The tower is in the corner of the car park at the rear

This was the location of what I thought was EE 13283

https://www.google.co.uk/maps/@51.7633745,-0.5839844...

It has Orange PCS on the other side of the cabinet. Is it a low power cell?

This link shows what I think is EE 35710 -

The EE labels says BILLET LANE SW 78395. There's a "micro dish" on the pole, and it points into town - possibly to EE 13006?

Perhaps the location of EE 13006 is also shared with Three and is on top of the building.

If not, then I'm at a loss as to the actual location.

Thanks for all your help

From home? Google street view and google satellite view, and then work out as close as possible where to drag it on cellmapper. This helps the algorithm that cell mapper is using from people running the Android app. If I was closer, I'd drive over and drive around the location as close to the mast as possible so the algorithm could GPS align. I'm miles away sadly.

Three and EE both jointly own the mast management company MBNL (goes back to around 2008) and for 3G they both shared a lot of equipment, but for 4G and 5G they have separate equipment cabinets, just share the physical mast and the antennas. Vodafone and O2 have a jointly owned mast management company called Cornerstone, or CTIL, but have their own equipment cabinets. This is to share physical locations, and increase national coverage for all.

I wouldn't trust the number on the noticeboard with anything you see electronic. The site number may have been correct for finding the site back when T-Mobile ran things, but that was before 4G and there is no connection with a site number and the eNB number you are getting from cellmapper over 4G. eNB for 4G/LTE, and a different number for 3G or 5G.

With that single equipment cabinet, and an Orange logo, its most likely a switched off old Orange 2G mast that EE is no longer using. Do you get a signal from it?

The microdish is a microwave network link but other than looking in that direction for another mast (maybe on the roof of a building) its not necessarily that helpful.

Perhaps the location of EE 13006 is also shared with Three and is on top of the building.

Could be easily shared, but they'd use different eNB and cell site numbers for each network. That last site on the block of flats looks to be covering the high street / shopping area very well.

EE often add additional capacity to shopping areas, in my town they have both Band 3(1800) and Band 7 (2600) frequencies in the shopping centre. Looking at the street view pictures of that last site, I'm sure there are multiple connections into each antenna panel.

It is a guess, but Cellmapper shows this as the only band 3 and band 7 site in the area, so I think you've found it!

I thought I was receiving a signal from it, but obviously I wasn't. I think I was getting a cell from Audley House. As I walked up the side of the valley (on the street) towards the 2G mast the signal increased. Seems a logical explanation.

I'll see if I can get closer later but probably won't be able to see anything due to the antennas being on top the building.

Thanks for moving the cells. Our property now shows it has coverage from two towers, each with two cells. Previously it was just 1 cell from 1 tower.

I suppose the use of Cellmapper north of the railway line hasn't occurred, because there doesn't seem to be any coverage (Bridgewater School area)

Do you know of a good site which would explain how to look for the best signal, possibly using the info from cellmapper, such as bandwidth, band and RSRP. Is one band better than another? (I don't have a choice - all band 3); I assume more bandwidth is better; and a low (closer to zero) RSRP would be beneficial. I don't want to bother you any more.

I'll pick up some PAYG SIMS for use at my parents. I'll find the green O2/Voda cell that was discovered in 2019 but isn't on streetviews that are dated later.

Thanks again.

Happy to help, another place with people whom can answer that sort of question is the Mobile Phones forum on Digital Spy. There are some quite technical people lurking on that forum.

Most modern handsets (phones) have the ability to aggregate, back to the iPhone 6s and Android equivalent. The mast will move you around between bands based on signal strength but also quality. RSRP (received signal received power) is only one measurement, there is also RSRQ, and the same backwards (can the mast hear your phone strongly enough).
