Questions about towers

Hello,

 

I have 2 questions about sprint's towers.

  • What is the range of each tower - For each 1900mhz tower, how many feet/miles does it go before going below -95dBm?
  • How can I check which 3G tower I'm currently connected to? Preferably without having to use any dial codes, since I'm on Cyanogenmod.

Thanks!

 

EDIT: Thought I'd also throw in,

 

Is it possible to get the stock dial codes back in Cyanogenmod (##DATA#, ##PRL#, etc.)? I know this was possible on the Evo 3D with replacing a certain system app, but I've forgotten the app name and am wondering if it's possible with the Galaxy S3.

Well with any wireless network(be it 2g,3g, 4g, Wifi, Wimax, even AMPS) the distance a signal can travel will depend on many possible things including geography (both natural and Urban geography) Urban zones are very difficult to meet capacity and coverage wise. trees, mountains and valleys and what else can drop that signal down below -96dBm. I work in a very old building in Center City Philadelphia and the signal is fine right outside but as soon as I walk inside the door signal begins to decrease. There's many variables in what will effect the distance a signal can travel.

 

Also the configuration of the site including how the sectors are setup and what power levels the sites are configured for.

I use CDMA field test to see what tower I am connected to if I want to know. I'm not sure how accurate it is but for me it seems to tell me the right tower when I cross check with Roberts map info on LTE sites. I think that when LTE is here though it will change because I think you can actually be connected to two different towers at the same time.

The range is between 5 blocks and 7 miles for -95dBM RSSI (-120dBm RSRP equivalence), outdoors...of course. The variability is because RF design and conditions are so variable from site to site. Some sites are designed to have very small cells to maximize capacity (usually in urban areas). Others are designed to be very large to maximize coverage (usually in rural areas).

 

There is no normal or average, as each site, and each sector within a site, is engineered specifically for that cell.

Robert, what's the expected maximum usable range/cell reach for LTE on 800Mhz?

Up to 30% - 40% further than LTE 1900, but it will be highly variable site by site depending on RF engineering and downtilt of the site.

I was in Timonioum, and according to Robert's completed sites map, I was about 3 miles away from the closest LTE site. But I was still getting 2 bars (iPhone 5 does show LTE signal strength) of LTE. Speedtest showed about 20Mbps. I was also close to a completed 3G site (my 1X was connected to this site.). If 1900 LTE can travel that far in this very urban area, 800 will be amazing!

I can answer the Cyanogenmod question! The dialer is not a Touchwiz/Sense one (depending on which phone you're using), which enables these features of accessing phone programming. You'll have to return to the stock based roms to get your dialer options back.

      Dish Network/Boost Mobile cell/5G buildout thread

      Yes! That does keep it from wandering off Dish and most importantly, reconnecting immediately (at least where there is n70). Thanks!

      Dish Network/Boost Mobile cell/5G buildout thread

      I have my Dish phone locked to NR-only.  That keeps it on Dish and only occasionally will it see T-Mobile NR SA for brief periods before going to no service. I also don't have mine band locked beyond that, except that I have some of the unused bands turned off just to try to reduce scan time.  Fortunately, my Dish phone is the one with the MediaTek chipset, so it has NR neighbor cells, and I can usually see n71, n70, n66, and sometimes n29 (market-dependent) through those regardless of which band it's connected to as primary. - Trip

      Excuse my rookie comments here, but after enabling *#73#, it seems that the rainbow sim V2? requires n70 (I turned it off along with n71 - was hoping to track n66) to be available else it switches to T-Mobile.  So this confirms my suspicion that you need to be close to a site to get on Dish.  Have no idea why they don't just use plmn. To test, I put it into a s21 ultra, rebooted twice, came up on T-Mobile (no n70 on s21).  Tried to manually register on 313340, but it did not connect (tried twice). I am on factory unlocked firmware but used a s22 hack to get *#73# working.  Tried what you were suggesting with a T-Mobile sim partially installed, but that was very unstable with Dish ( I think they had figured that one out).  [edit: and now I see Boost sent me a successful device swap notice which says I can now begin to use my new device.  Sigh.  Will try again later and wait for this message - too impatient.]

      Hopefully this indicates T-Mobile hasn't completely abandoned mmwave and/or small cells? But then again this is the loop, so take that as you will. Hopefully now that most macro activity is done (besides rural colo/builds), they will start working on small cells.
