Detailed Description

This structure contains the parameters for HDR Signal Strength Information

Parameters:
rssi 
  • RSSI in dBm (signed value).
  • A value of -125 dBm or lower is used to indicate No Signal.
    • 0xFF - Not Available
ecio 
  • ECIO value representing negative 0.5 dBm increments, i.e., 2 means -1 dBm (14 means -7 dBm, 63 means -31.5 dBm).
    • 0xFFFF - Not Available
sinr 
  • SINR level.
  • SINR is only applicable for 1xEV-DO.
  • Valid levels are 0 to 8, where the maximum value for:
    • 0 - SINR_LEVEL_0 is -9 dB
    • 1 - SINR_LEVEL_1 is -6 dB
    • 2 - SINR_LEVEL_2 is -4.5 dB
    • 3 - SINR_LEVEL_3 is -3 dB
    • 4 - SINR_LEVEL_4 is -2 dB
    • 5 - SINR_LEVEL_5 is +1 dB
    • 6 - SINR_LEVEL_6 is +3 dB
    • 7 - SINR_LEVEL_7 is +6 dB
    • 8 - SINR_LEVEL_8 is +9 dB
    • 0xFF - Not Available
io 
  • Received IO in dBm.
  • IO is only applicable for 1xEV-DO.
    • 0xFFFFFFFF - Not Available
