 Receiver Noise Figure 
 
 
   
 
 
 Scalar 
 
 
 dB 
 
 
 Equipment-specific noise figure of receiver. It is used to calculate the noise floor. See Section‎1.2.2 
 
 
 
 
 Handover margin 
 
 
   
 
 
 Scalar 
 
 
 dB 
 
 
 Specifies the maximum difference between the links in users active list. The actual active-list selection is based on pathloss calculations. 
 
 
 
 
 Call drop threshold 
 
 
   
 
 
 Scalar 
 
 
 dB 
 
 
 Threshold to determine call drops. It is used by the power control to determine if a user should be dropped when not meeting exact target requirement. 
 
 
 
 
 Voice bit rate 
 
 
   
 
 
 Scalar 
 
 
 kbps 
 
 
 it is used to calculate the processing gain. See Section ‎8.7.1. 
 processingGain = 10*log10(systemBandwidth (MHz) / voiceBitRate (kbps) * 1000); 
 
 
 
 
 Reference bandwith 
 
 
   
 
 
 Scalar 
 
 
 MHz 
 
 
 Bandwidth of the system. It is the same for either UL or DL. 
 
 
 
 
 Voice activity factor 
 
 
 - 
 
 
 - 
 
 
 - 
 
 
 It is set to 1, i.e. 100% (all voice users that are generated are active). It is not editable. 
 
 
 
 
 Minimum Coupling Loss 
 
 
   
 
 
 Scalar 
 
 
 dB 
 
 
 The minimum path loss. It is used in the calculation of the effective path loss depicted in section ‎7.6.1 
 
 
 
 
 Link Level Data 
 
 
   
 
 
 Function (X,Y) 
 
 
   
 
 
 Drop-down selection of Link level data look-up functions from Library. It is user's responsibility to choose an appropriate set of data. See Section ‎8.5 for further details
