Introduction to Radio Communications Principles. What is Communication? What is a radio wave? Wider offsets would be used on higher frequency bands.

A repeater is normally an automated, unattended station. A control operator must for legal reasons be capable both of monitoring the retransmitted signals and remotely silencing the transmitter should problems occur, but all routine tasks such as periodic CW or voice station identification are normally handled by an automated controller board.

The transmitter is only activated when a signal is present at the input; some repeaters may also require specific tones to be present on the input signal. A timer is also provided to stop the repeater if more than three minutes pass without any break in transmission so that a fault condition does not leave the transmitter continuously on. Operating procedure on repeater stations differs slightly from direct communication, in that the repeater is on a fixed frequency monitored or actively used by many local amateurs.

Multiple stations attempting to transmit via the same repeater at once can be problematic. For example, an events facility would have a number of different teams, from security, food vendors and technical teams, working to make an event run flawlessly. Having different channels for these various departments makes for seamless communication — and within that one team requirement. Unique Applications — The latest in digital two way radio technology offers exciting features that some organizations have taken advantage of, including applications like work ticket management and man down features.

Users of these applications and more will require a backbone of infrastructure that better allows these apps to work. The MotoTRBO line of radios features a number of applications, but they will work more efficiently with the use of a repeater. Wide Area Coverage — This is often a necessity for organizations with employees on the move — such as transportation and logistics, along with a number of public safety and government departments. In order to ensure consistent conversation with dispatch or the base of operations, a wide area coverage zone may be a necessity — and having so has been shown to increase efficiency and productivity in the workplace.

Often times, however, companies like Nova Communications offer wide area coverage for a monthly rate. Our 4D network , which offers seamless communication between Halifax and Moncton is an example — and is quite popular for users who want that service and coverage.
