cell tower question


Recommended Posts

I use NetMonitor app. It works really well for me. However I have heard that some people have problems with the accuracy with NetMonitor in some markets or with some devices. Results may vary.

Netmonitor works really well for me in the Chicago area. Keep in mind it only locates what the tower transmits for its location. I did have a couple towers around me that did not transmit a location and if my phone switched to one of those towers metmonitor would not change the location of the map from the previous tower.

 

It was one of the few apps I found that works on cdma.

 

As network vision has moved though my area the towers that were not reporting their location now do. I'm not sure if that will happen everywhere.

I used to have the issue on my E4GT where it did not like to update when I connected to a new site. However, on the GNex, it always updates as I pass on site to site. Nice little surprise with my upgrade.

 

For me, OpenSignal site locations have been so bad. But I haven't tried it for probably over a year because the results were so poor for me. I should probably give it a try again.

Interesting. I experienced the location issue with my EVO 4g and EVO 4g LTE. It wasn't until their SID and NID changed with NV that netmonitor was able to locate them. I guess broadcasting the tower location is not part of the cdma standard? I imagine it would need to be done for 911 location identification.

None of the VZW towers in my area broadcast their lat and long.

I use cellmapper to find locations of towers not broadcasting correct lat and lon. You can set the app to upload your signal data and the site uses this crowd sourced data to compute tower locations and map out the sectors. It takes a bit of driving around but the more data you upload the better the maps get. You can look at the maps of Austin I've been updating as an example.

 

Set Country to 310 and provider to 120.

I had heard a rumor about that from another source. I guess for me that confirms it. I wonder if that changes 911 location accuracy.

My work VZW phone will not show locations with any app. VZW blocks it. However, my Sprint devices will show VZW lat/long when roaming. Go figure.

I wonder if a custom rom running on a VZW phone would show lat lon? I think when I had my VZW GNEX running a rooted rom it showed lat and lon in netmonitor and cdma field test but i have horrible memory.

I wouldn't know. The State of New Mexico frowns on us rooting and installing custom ROMs. It can even be grounds for termination.

I heard (but don't know) that in the iPhone field test screen you can look at the Serving PN offset which will give you the degrees off north of the current cell you are on (from the tower's point of view), and active set pilots will show the same for the towers you can see... So in my case I look on the map and see 255 and 96, which would indicate a tower almost to the immediate west of me and another to the north east and indeed I find Sprint sites at those exact locations and within reasonable distances (1 mi and 3.5mi respectively).

 

No clue if this is correct or not. I can see base ID under the 1X info but haven't found any way to correlate that with a Sprint site.

Talking with netmonitor support about app issues I was having, I found that their data comes from a Google database. He said that Google collects location data from Android devices via the location service and creates a DB of cell towers. The problem I've found is that the Google locations, in comparision to the great data that Robert has here, are down right terrible. Over a mile off in random directions, sometimes pointing you in the completely different directions.

Deployed PN offsets have no relation to their compass orientations.

    • Just mapped at least 8 5G small cells (all 109xxxx gNBs) while driving on the Southern State. They all seem to be n25/n41. I'm pretty sure nearly all of them are upgrades of existing small cells as opposed to new builds but I'm glad to see Crown Castle/T-Mobile hard at work getting midband 5G on all of these. Each of the unpinned gNBs belong to 1-2 small cells. I still can't pin these sites until the Cellmapper devs give us the option to split cells for 5G sites.
    • Their offers have been crap recently, so this is just more evidence to not buy from T-Mobile. 
    • T-Mobile Will Soon Prevent Early Payoff Of Phones Receiving Bill Credits If you finance a phone with T-Mobile it will remain locked until paid off but now you won't be able to pay off early. If you don't currently purchase your phones from the manufacturer here is another reason it might be a good idea.
    • Was in Red Hook again and I swear there are more Link5G sites as there are Verizon, T-Mobile, and AT&T small cells combined in the entire neighborhood. It seemed like every other street I turned down had one installed. Hopefully carriers will start hopping on them soon. Seems like a lot of effort to go through for no one to use them.  — — — — — T-Mobile converted the Sprint site on top of NYU Langone Brooklyn in Sunset Park. I first mapped one sector of it back in November 2023 but I thought it was a small cell so I never pinned it but I ran into another sector today which caught me off guard. I'm unable to find a permit for the conversion so it's definitely a surprise. There's another T-Mobile site 1 block away that T-Mobile initially installed back in 2019 so I'm kinda surprised they're keeping both considering the Sprint conversion is on a much taller building and could potentially provide much better coverage to the entire area.  — — — — —  Old permit for this new install expired but a new one was recently issued. It's gonna be similar to the site at 360 Forman St in Brooklyn Heights. Permit calls for only 3 antennas to be installed so I'm assuming it gonna be Band 2/41/66 and n25/41 only which is a bit of a downgrade from the now decommissioned full build that was on 871 7th Ave but in it's current state the nearest macro is a few blocks away and a small cell at Broadway and 55th is doing a lot of heavy lifting in the area so anything helps.
