A protocol is a set of "rules" that govern the form, format, data content and information flow sent over communication links that connect different devices. Put simply, a protocol is a computer "language" for communicating information. Paging networks use a wide range of protocols to provide communications between different network components. Each protocol has a specific purpose but, in concert with each other, they support all of the features and services that the radio common carrier (RCC) wishes to provide. Some protocols that have been developed are specific to a particular manufacturer's set of equipment, while other protocols have become industry standards.
Paging protocols can be broken down into five major groups shown graphically in Figure 1. These groups and their functions are:
