  • Information access interfaces: LTE modem, Ethernet, Wi-Fi
  • Functionalities: radio monitoring, interference analysis & alarm generation
  • Measurement variables: total power, ACLR, SEM (spectrum emission mask), OBW (occupied bandwidth), RB (resource block) usage
  • Spectrum display options: marker display, display mode (min/max, average, accumulation)
  • Other RF measurements: RSSI, SINR, Tx Pwr, RSRQ, CQI , etc.
  • Software upgrade: Local GUI or via remote client

Key Features - Details

Spurious emission detection

  • Apply the patented spurious emission positioning algorithm/zone its location
  • Single-tone spurious emission and broadband noise measurement/discrimination
  • In-band noise separation/report by utilizing OFDM signal characteristics

Inspection variable measurement for RF stations

  • Periodic inspection of RF interference in the RF stations (BTS/repeaters) for efficient management of RF resources
  • Automatic measurement of inspection variables (total power, channel power, ACLR, OBW, SEM ) in the RF stations according to the operator setting
