Lecture Notes


  • current implementation did not convert base station transmit power into dB, leading to

Signal to Noise ratio (SNR)

  • SNR, calculated from resulted in -7dB, due to coding gain. Assumed
    • Signal for voice, and for data in GSM resp. GPRS
  • assumed that GSM needs SNR of 7 dB

UMTS receiver sensitivity

  • specs require for


UMTS til GSM handover for tale: -104 dBm (normal -100 dBm) UMTS level

UMTS data is stable until about -117 dBm, with handover at -115 dBm
