Part 2 Background

      2.1                       The 3.4 GHz band has been designated for spectrum licensing in specified parts of Australia. Radiocommunications receivers of apparatus licensed and class licensed services may operate in and adjacent to this frequency band.  These receivers may suffer interference from unwanted emissions and blocking caused by a radiocommunications transmitter operating under a spectrum licence in the 3.4 GHz band.

      2.2                       Unwanted emissions are by-products of a radiocommunications transmitter's emissions and include broadband noise, harmonics, intermodulation products, transient signals and other spurious signals.  Blocking occurs when a high level off-tune signal overloads a radiocommunications receiver's front-end and causes a degradation in the quality of the wanted output signal. Intermodulation products can be generated in-band in the input stages of receivers in the presence of two or more high level signals at the receiver input.

      2.3                       These guidelines have been made for the management of
