Why does Phone connect to a tower further away


Recommended Posts

Does anyone know why a phone chooses one tower over another?

 

A handset is programmed to idle on/connect to the site with the most favorable signal level, and that may not be the closest site. Additionally, the handset is programmed to seek the highest protocol revision (e.g. LTE > EV-DO) that it supports. For example, the closest site may not yet have LTE deployed, but the LTE signal from a more distant site is usable. Finally, keep in mind that CDMA1X, EV-DO, and LTE signals are all tracked independently, so a handset can idle on/connect to different sites for the different airlinks all simultaneously.

Thats good info thanks. I actually visted one of the sites a mile from my job that is due to be a NV upgrade. Its only a mile away but lord know based on my covereage at my job I have never connected there. Do you know any other Apps like Opensignal that I can use to compare?

Try CDMA Field Test. Open SIgnal's tower locations are inaccurate guesswork based on crowdsourcing.

 

One caveat: The tower coordinates captured by CDMA Field Test and similar apps will be the lat/lon broadcast by the sector base stations and captured by the Android device. But there seem to be two distinct situations: On some towers, all sector base stations will squawk the actual coordinates of the tower; on others, each sector will squawk different coordinates that are offest some distance away from the tower.

I was thinking this while I was at home depot this morning. So its possible for a device to get an lte signal from one tower but voice on another at the same time?

And be using both signals. Meaning I'm on a call and refreshing Twitter at the same time

Absolutely. Different sectors on the same site or even different sites altogether. And this has long been true of CDMA1X and EV-DO, too.

Voice and data simultaneously is a given, that I already know.

    • I am using Starry for my home internet. I hope it doesn't collapse and make me go to cable.
    • Some of the other plans have been throttled, like the ED1500.  Fixes ultimately came, but it took several years iirc.  I moved on to the Sprint Max.  One of my hopes was I would get the billing transition sooner. Nope.  Wonder if they are going after the static IP.  Likely work around is VPN, especially with a smaller more obscure service.  Rumor has been T-Mobile would start transitioning Sprint Billing customers in earnest next quarter  -- wait, isn't that always the promise?
    • I've been using Samsung devices for a couple years and I've never been able to mirror without wifi? I'm not sure what exactly you're talking about.
    • Is there a way to mirror this thing to my smart tv without having to have wifi, the way I've always done with Samsung phones both at home and at work? Samsung phones do it with TCL and other smart TVs as well, not just Samsung TVs.  Samsung has saved me a ton of money over the years in this regard.  If I can't do this then it will absolutely be a deal breaker for me.  I still have the Samsung phone and can use it to mirror but I shouldn't have to default to a three year old phone for this.  
    • So, I've now gone to a legacy Sprint store and talked with various agents on chat, and I keep getting redirected to scripts, with folks throwing solutions at the wall that I know won't work. I have the Sprint Unlimited Plus business plan, which includes 1080p streaming (8 Mbps throttle). But since going TNX I've been throttled to 2.5 Mbps or less for video. Who do I contact and how do I ask them to fix this? 'cuz it sounds like someone has gotten this fixed before?
