Hello,
I'm working on a product using the nRF9160 and facing challenges with poor LTE signal strength, leading to significant power drain when the device goes offline. I have a few specific questions and would appreciate any recommendations:
1. Modem Behavior in Low/No Signal:
- How does the modem behave when transitioning from good to low/no signal?
- On my dev kit, the modem can take up to 60 seconds in a high-power searching state before updating the registration status. Is there a way to detect this state earlier to reduce power drain?
2. RSRP and RSRQ Thresholds:
- What levels of RSRP and RSRQ are considered too weak for a reliable network connection?
- Are there guidelines for the minimum acceptable signal strength for stable operation?
3. Modem Signals for Connection Quality:
- What signals or indicators does the nRF9160 modem provide to assess connection quality to the LTE tower?
4. General strategies for Poor LTE Signal Environments:
- Are there any recommended strategies or best practices for optimizing the nRF9160's performance to reduce power drain in weak LTE signal areas?
