Voice radio communications guide for the fire service

The past few decades have seen major advancements in the communications industry. Portable communications devices have gone from being used mainly in public safety and business applications to a situation where they are in every home and in the hands of almost every American man, woman, and child. As users are added, there is more stress on the system; there is only so much room on the radio spectrum. The communications industry and the government have responded by making changes to the system that mandate additional efficiency. These advancements have improved radio frequency spectrum efficiency, but also have added complexity to the expansion of existing systems and the design of new systems. Some of these advances in technology are mandated by the Federal Communications Commission (FCC), while others are optional. The costs and operational effects of these changes are significant.
