entire network. We need to be careful that these hill top systems are well engineered with appropriate
filtering and antenna spacing so that the repeater radios operate under the best possible conditions.
Hot standby repeaters can also improve the repeater integrity. Here is an analogy… It’s hard to
have a quiet conversation when a crowd is shouting all around you. So, make sure you give your
RiPEX repeaters the chance to communicate in a reasonable RF environment. Sometimes a different
layout can significantly reduce the vulnerability of a radio network.
• When total throughput is important, as is typical in report-by-exception networks, splitting the network
into several independent or only slightly overlapping areas of coverage can help. The placement
of repeaters which serve the respective areas is crucial. They should be isolated from each other
whenever possible.
