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
