FIELD: radio engineering, communication.
SUBSTANCE: in one example, this is accomplished by extracting signals and messages recorded in the field and injecting them while the protocol tester operation. In another example, the surrounding radio environment is reproduced by generating the channel impulse responses in the beam tracer when interpolating them in the channel emulator and supporting the interpolation using subsequent processing. In the following example, the surrounding radio environment is recorded using a mobile terminal in the field. In the following example, the natural surrounding radio environment in produced by reconstructing the realistic loads of the cell and, as a result, mutual interference within the cells for a given test device.
EFFECT: increase of noise immunity.
