Maximum RF ERP/EIRP: 20.03 dBm (CDMA1X/EV-DO 850), 24.46 dBm (CDMA1X/EV-DO 1900), 20.25 dBm (CDMA1X/EV-DO 800), 28.35 dBm (GSM 850), 25.05 dBm (EDGE 850), 29.44 dBm (GSM 1900), 24.13 dBm (EDGE 1900), 21.41 dBm (W-CDMA 1900), 19.63 dBm (LTE 1900) Elsewhere I saw something to the effect that 23dBm was a threshold for good ERP. Does that differ with the type of signal?
Is 19.63dBm for LTE 1900 weak?
What about the strength of the various GSM signals? Does Sprint support any of them? Or are GSM signals only a factor if you are traveling out the USA and get a SIM to use the phone say in Europe or Canada or Mexico, or the Philippines?
