Cell towr metrics?

I’ve just received my nw Nokia 5G gateway, and while it is not perfect, it does work.  I can use my vpn, I can get my Eero mesh system to interface just fine.  However, I’d like to figure out what acceptable cell tower metrics are.  I’m totally blind, so I can’t see the touch screen at the top instead, I use VoiceOver on the iPhone to look at the cell tower metrics on the app.  Is there anybody who knows that the proper values are?  Also, is there any kind of beta firmware for this device to test out some of the new features?

    Hi there,

    So these are my metrics from my t-mobile router:

     

    RSRP

    -94 dBm

     

    SNR

    8 dB

     

    RSRQ

    -12 dB

     

    RSSI

    -67 dBm

     

    Secondary Signal

     

    Connected

     

    RSRP

    -92 dBm

     

    SNR

    19 dB

     

    RSRQ

    -11 dB

    using VoiceOver, it’s a little difficult to tell which is which.  Are these reasonable?  Are there any hacks to make the ping time, and jitter more consistent?  I notice that I an get 100-200 MBPS down, but then it dropped right off.  Previously a week ago, I was getting 3/400 MBPS down, and that was allowing me to work with my vpn that I use for work.  Just trying to get that kind of signal back.

    The metrics are below. Please note that many people are getting good and consistent service even though some of their metrics may fall into categories decribed as Fair to Poor in the tables below. My RSRP and SINR both are usually in the Fair to Poor range listed below. My RSSI and RSRQ are usually Good. And I typically get 90+ downstream and 6+ upstream.

    RSRP    
    >= -80 dBm Excellent Strong signal with maximum data speeds
    -80 dBm to -90 dBm Good Strong signal with good data speeds
    -90 dBm to -100 dBm Fair to poor Reliable data speeds may be attained, but marginal data with drop-outs is possible. When this value gets close to -100, performance will drop drastically
    <= -100 dBm No signal Disconnection

     

     

    RSRQ    
    >= -10 dB Excellent Strong signal with maximum data speeds
    -10 dB to -15 dB Good Strong signal with good data speeds
    -15 dB to -20 dB Fair to poor Reliable data speeds may be attained, but marginal data with drop-outs is possible. When this value gets close to -20, performance will drop drastically
    <= -20 dB No signal Disconnection

     

     

    SINR    
    >= 20 dB Excellent Strong signal with maximum data speeds
    13 dB to 20 dB Good Strong signal with good data speeds
    0 dB to 13 dB Fair to poor Reliable data speeds may be attained, but marginal data with drop-outs is possible. When this value gets close to 0, performance will drop drastically
    <= 0 dB No signal Disconnection

     

     

    RSSI    
    > -65 dBm Excellent Strong signal with maximum data speeds
    -65 dBm to -75 dBm Good Strong signal with good data speeds
    -75 dBm to -85 dBm Fair Fair but useful, fast and reliable data speeds may be attained, but marginal data with drop-outs is possible
    -85 dBm to -95 dBm Poor Performance will drop drastically
    <= -95 dBm No signal

    Disconnection
