Question: What is the boundary frequency between out-of-band and spurious emissions for UE categories NB1 and NB2 in uplink transmissions?
Option 1: FOOB = 1.7 MHz
Option 2: FOOB = 2.5 MHz
Option 3: FOOB = 3.0 MHz
Option 4: FOOB = 4.0 MHz
Explanation: For UE categories NB1 and NB2, the boundary frequency between out-of-band emissions and spurious emissions in uplink transmissions is specifically defined as FOOB = 1.7 MHz to ensure proper spectral separation and minimize interference with other radio services.
