Whether you are a system manager contemplating upgrading to digital radio or you just want to learn the advantages of digital radio over analog, this course will directly identify the benefits of digital radio.

From flexible data capabilities to better spectral efficiency, digital radio has some powerful advantages of modern digital standards that have emerged over the last few decades. There are other ways in which digital radio offers advantages over analog as stated in the Communication Systems: Digital vs. Analog lesson.

You can view them by watching the video... Continue Reading

Have you ever been confused about the difference between downlink voting, uplink voting or voting in general? Have you heard of a simulcast network, another kind of voting network?

All the information you need to differentiate between downlink voting, a process that takes place in the subscriber unit, and uplink voting, a process that takes place in the network, is included in the Communication Systems: Voting and Simulcast Networks lesson.

Along with explanations and diagrams, this lesson also includes a description of how a simulcast network operates.... Continue Reading

Manually checking through radio channels for communication activity can cause problems in the way of missed calls as a result of being on the wrong channel. Fortunately, there is a better way of checking for activity.

The lesson Communication Systems: How scanning works on the Tait Radio Academy explains how scanning, an automatic process, checks each channel in turn to see if there is any activity occurring. If there is, the radio will lock onto that channel and then send the audio to the speaker so that the radio user can hear it.

Scanning is also flexible in the... Continue Reading

As previously discussed, the use of a repeater can solve the problem of an obstruction in line of sight conventional communications. This benefit is part of installing a repeater system, but there are also other benefits that can occur when there is no obstruction.

The lesson Communications Systems: How does a repeater system work? continues on from the Modulation and Radio Building Blocks lesson to explain how repeater systems work and how repeaters are not only excellent for ensuring communication can occur, but also for extending communication range.
