1 GSM-R = -85dBm I = -94dBm 9dB C/I Note 1: The I should be the sum of Rx thermal noise, co-channel, adjacent channel and Unwanted Emission. Here only UE is considered, using “Realistic” levels Note 2: All levels at rail track GSM 925,4MHz Max allowed UMTS interferer with Improved Receiver -25dBm/5MHz Max allowed interferer due to Unwanted Emissions -22dBm / 200kHz -29dBm / 5MHz UMTS / LTE 927,6MHz Input UIC 2nd CG meeting Dec 2013 Note: Levels at radio antenna connector Effects of Unwanted Emission levels 29-6-2016 CG-GSM-R(13)037
