10.4. Deployment 

Scenarios 

 

This section examines two types of deployment scenarios: co-located (same rooftop), and 
adjacent area.  

 
 

10.4.1. Co-located 

Deployments 

 

It is possible to deploy more than one AN-30 system from the same rooftop to support 
multiple links, however, it is important to consider issues that may arise from co-channel 
and adjacent channel interference. 
 
Co-channel interference results when two systems operate simultaneously in the same 
channel. This must be avoided by selecting different channels in the AN-30 

Configuration 

screen. Adjacent channels are acceptable; however, it is important that the 

adjacent channel does not exceed the acceptable channel-to-interference (C/I) ratio for 
the system, as shown in Figure 24 (C is the desired channel, while I is the interferer).

10.4.2. 

Adjacent Area Deployments 

 

During the installation process, it is important to ensure there is no potential for 
interference from other systems deployed in adjacent areas.  Figure 25 presents a simple 
deployment configuration to illustrate the potential interference that may arise from 
adjacent area sources (Users 1 to 4 in Figure 25).  
 
The desired communication link is between Terminals 1 and 2. The link between Users 1 
and 2 must operate in an adjacent channel to avoid interference with the desired link.  
Users 3 and 4, on the other hand, can operate co-channel since they are outside the 
narrow beam width of both terminals.  Narrow beam widths are one feature of the AN-30 
to help address potential interference.
