Signal Strength Question

Recommended Posts

I'm wondering if someone can answer this for me in regards to Sprint. What exactly is the reason my phone will have -120db in some areas and -60db in others? Is it distance to a tower? is it line of site? is it a combination of the two?

 

Second when and where did Sprint go wrong or if they did even go wrong? Was it the smartphone explosion? Was it something else regarding the network. What happened that I went from pretty good service to what I have now? I have always had spotty service over the years but overall it worked so I'm just want to know what happened over the years..The more technical the better..

Correct. At typical cellular frequencies, path loss is a function of both distance (inverse square law) and obstruction to line of sight.

Yes, that is part of my theory. Here is the thumbnail sketch. Sprint deeded the WiMAX buildout to Clearwire. Clearwire got in financial trouble and could not complete its buildout. Meanwhile, smartphone adoption/usage exploded. And the Sprint EV-DO network could not cope with the demand, much of which was expected to be offloaded to WiMAX.

    • What devices should do, and what they actually do, are two very different things! As you've probably heard me mention countless times, many of those screens get information in a proprietary manner directly from the modem; apps like SignalCheck can only get what the OS is reporting. I did find your earlier reports, and as I guessed, the OS was reporting valid signal strength. I will try to figure out a solution.
    • Service mode shows the SIM as having no service, so I would think the device should report that. I believe I sent a diagnostic report a little while back—can you check to see if you have it?
    • Interesting, that doesn't happen on my P7. Can you send me a diagnostic report the next time you see that please? Hopefully the phone isn't actually reporting the -115, that will be tricky.
    • Hey Mike—another dual SIM bug. If one SIM loses service, it doesn’t disappear from the app.  I’ve seen this a couple times—my Dish SIM will lose service (confirmed in service mode), but SCP won’t stop displaying -115 or so. And it logs a data point at that signal every time the location updates.  Along the same lines, I have a custom trigger set up for 313340 (Dish), and the custom trigger keeps firing when this is happening. 
    • TLDR: not really 😂 With dual SIM, initially I was struggling to keep the info from each SIM separate but updating properly. I figured out how to get each to update without negatively impacting the other SIM's process.. which caused those processes to run on separate threads. On some devices (notably your e5 Play), the OS doesn't like the separate threads updating the UI. But it was only a very small subset of devices. And at first, the crash reports gave the correct crash reason but it was pointing to unrelated parts of the code. Once I cleaned up some other bugs, the crash reports pointed me directly to what I needed.
