scope:
The present document gives, initially, a basic overview of how a fixed point-to-point system is allocated an EIRP guaranteeing predetermined link availability. It then reviews the methodology for deriving the parameters necessary for the sharing of FS systems in an environment with different equipment classes and capacity. The methodology is based on the limitation of noise and is not exclusive. In addition a method for calculation of RSL based on normalized values is presented
The present document highlights the primary parameters from European standards, which are vital to the development of an assignment system. These parameters are:
• Transmitter radiation patterns.
• Receiver sensitivity.
• Receiver adjacent channel rejection.
• Receiver co-channel rejection.
In addition to these parameters the antenna radiation profile and, if fitted, the ATPC operating characteristics will have a major effect on link density.
