Lecture Notes
Experiences
- 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

Notes
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
