Reading material on statewide communication systems

In any communication system, no matter how simple or complex..it comes down to the actual individual that is the end-user and is accessing the system. As you add more complex "bells' & whistles" in a dispatch environment that are "user controlled" the level of expertise required to successfully manipulate the device increases to a point where the "end user" might require an advance "degree" in "device management" just for that particular type of unit. With the removal of "local area" participants and the addition of "remote" unaware dispatchers without individual knowledge of the particular situations, using "computers" to enhance their awareness we all will be in bit of a predicament should we require assistance..also radio coverage, network design & control, info database..you are on your own!!!
