scope:
The present document covers the minimum performance requirements for terrestrial fixed services radiocommunications equipment, as given below, in the frequency band 48,s GHz to 50,2 GHz.
The present document specifies the performance criteria for digital signals.
As the maximum transmissible rate in a given bandwidth depends on system spectral efficiency, different classes are defined:
- Class 1: Equipment based on a minimum 2-level modulation scheme (e.g. 2-FSK or equivalent).
- Class 2: Equipment based on a minimum 4-level modulation scheme (e.g. 4-FSK, 4-PSK, or equivalent).
Safety aspects are outside the scope of the present document.
