Introduction

The 3 400-4 200 MHz band is allocated worldwide on a primary basis to the FSS. This band or parts of the band can be heavily used by the FSS for space-to-Earth transmissions. There are primary allocations to the mobile service and to the fixed service within the 3 400-4 200 MHz band. In various regions, many administrations are introducing BWA systems in all or portions of this frequency band.

This Report examines the possible compatibility between BWA and FSS networks in the range 3 400-4 200 MHz. In addition, the potential of the FSS receiving harmful levels of interference due to unwanted emissions from BWA systems is investigated.
