Lora radio receiver rssi

Wireless & IoT LoRa (Long Range)

I’ve read that Lora radio rssi has a low end of -120. My RX is showing a limit of -105. Can anyone shed light on this?

I’m very new to all of this, so I will appreciate any input.

Thanks

That -120 is under optimum or controlled conditions. Your setup may have impeding variables. Do you strictly need values past -105?
