Signal Strength:
For 4G networks (CAT1\ LTE), RSRP to represent signal strength, the corresponding signal strength is as follows:
  • Excellent signal: RSRP >-85dBm
  • Good signal: RSRP=-85~-95dBm
  • Medium signal: RSRP=-95~-105dBm
  • The signal is bad. RSRP=-105~-115dBm
  • Signal Range: RSRP <-115dBdbm

For 2G networks, the corresponding signal strength is as follows:
  • 0 -113 dBm or less
  • 1 -111 dBm
  • 2…30 -109… -53 dBm
  • 31 -51 dBm or greater
  • 99 not known or not detectable


network_status

Bitwise parameter, each bit meaning:

  • 0: If started the 4G module
  • 1: If connected with SIM
  • 2: If registered the GSM/4G network
  • 3: If it is roaming
  • 4: If registered the GPRS network
  • 5: If TCP connection set up
