What is the definition of 'directional requirement'?
The carrier with the lowest carrier frequency transmitted/received in a specified frequency band
The direction where the maximum EIRP is found
The sensitivity for an isotropic directivity device equivalent to the sensitivity of the discussed device exposed to an incoming wave from a defined AoA
The lowest declared EIS value for the OSDD's declared for OTA sensitivity requirement
The requirement which is applied in a specific direction within the OTA coverage range
