3G Signal Strength Query | Thales IoT Developer Community

EHS6T: From various forums it was recommended that for satisfactory 3G GSM transmissions, there were recommendations to disable 3G transmissions if signal strength was below -105 dbm and -5db S/N. However if the 3G levels remain at this level, you can end up waiting for a long time before you can do any GSM transmissions in poor signal areas. Is it possible to force the modem to try and use 2G transmission, if signal strength adequate, if the 3G remains too low for a timeout period?
Are the above 3G signal, S/N levels practical in practice - or can lower levels still provide satisfactory transmission??
