Cell Tower IDs


Recommended Posts

Is there any data we get from an app like RF Tracker or Network Info that can be used to positively ID what tower we are connected to?I know there is the whole issue about different sectors being assigned different BSID, but does the Network ID or System ID give us anyway to determine exactly what tower we are connected to? What info exactly does the System and Network ID provide?

The IDS captured by the apps are from the CDMA network hierarchy. There is no resource we know of here that correlates them in a handy table with the Sprint tower IDs. But with the S4GRU maps in hand as a sort of Rosetta Stone, you know where the towers actually are. So when surveying with the apps to capture the CDMA IDs and the coordinates they squawk -- I prefer CDMA Field Test -- it is usually possible to figure out which tower is which. You might need to deliberately circle around each tower site to log all the BSIDs, which typically are sequentially assigned to the three sectors of each tower.

 

Each tower usually fits one of two patterns:

  • All three sector radios broadcast the actual coordinates of the tower.
  • Each sector broadcasts unique coordinates that are offset some distance away, and the three points form a triangle around the tower.

Thanks for the explanation. Do we have an estimate of what percentage of towers broadcast their true coordinates vs "sectorizes" them? I know my local tower goes the sector route, but I haven't really paid attention to others in the area.

It varies by market.

    • Great job on your analysis of small cells versus the 3.45GHZ and the population coverage requirements. I wonder if the fcc is stalling because they may address the key limitation of of 2.5: the convoluted frequencies. Not sure how they would get there, but it would be better public policy if you could actually use a single license in current times, ie 5, 10 or 20MHz. Of course they could also go in more of a nonprofit or small business direction. But most likely they will keep it as planned given how messy the transition would be. In many/most metro areas BRS/EBS is fully licensed. Would be nice if they put pressure on the squatters.
    • I didn't actually look at the buildout requirements before making that comment - they're definitely going to have to deploy on macro sites if they want to hit the buildout requirements. PEA001 has a population of 25,237,061, of which they will have to hit 45% in 4 years (11,356,677) and 80% in 8 years (20,189,649). If they were to cover the entirely, all five boroughs, of NYC using only small cells (something I'd say is impossible considering their current small cell density), they'd only be covering 32% of the population in the PEA. And this is with spectrum that only adds 300Mb/s per sector and will likely have only 50% the range of their current n41 equipment. Doesn't really seem worth it to me. I'm of the opinion that they're looking to hedge their bets in further EBS/BRS acquisition. 
    • These strand mounts also are deployed with Band 46 (LAA), in my experience. I have yet to encounter a strand mount with exclusively 2/66. 
    • Bought a esim "sim" card a few weeks ago that operates in all of my more current phones according to its app. It arrived a couple of weeks early from Berlin.  Now if my MVNOs would get moving and support more than iPhones and rarely Pixels so I can test this thing. https://esim.me The only item really troubling so far is reviews in google play store keep getting deleted, even 5 star ones.
