The aforementioned formulas are also applicable to absolute emission floor emission_floorILT (dBm) . This emission floor mask can be described by a triplet (frequency offset (MHz), emission floor (dBm), reference bandwidth (kHz)).

Figure 376: illustration of the emission mask and the unwanted emission floor mask


The real emission is bounded by the emission floor by the following equation and illustrated in Figure 377.

Note that the value of the emission_floorit is scaled to the VLR bandwidth. This means that assuming a VLR bandwidth of 200 KHz and the value of the Emission mask and Unwanted Emission floor as presented in Figure 376, the following emisssionit are calculated:


for a fILT = 900.3 MHz and fVLR = 900.0 MHz:

emissionILT = max (-30 + 5 + 0 , -10)

emissionILT = -10 dBm;


for a fILT = 900.0 MHz and fVLR = 900.0 MHz:

emissionILT = max (0 + 5 + 0 , 13)

emissionILT = 13 dBm;
