Reference excerpt

Motorola Trunked Radio for telecommunications is a trunked radio system developed by Motorola.

Types Type I Type II Type IIi Hybrid Type II SmartZone Type II SmartZone OmniLink Type II VOC Motorola Type I and Type II systems achieve the same thing in a slightly different way. One important distinction between these systems is the amount of data transmitted by each radio when the operator pushes the PTT button. A Type I system transmits the radio's ID, its fleet information, and the subfleet information. A Type II system only transmits the radio's ID. What’s the difference? In Type I systems, each radio in the trunk group individually transmits its own affiliation. In Type II systems the trunk system maintains a database that determines each radio's affiliation. Another difference between the systems is that Type I systems are arranged in a fleet-subfleet hierarchy. For example, it is possible for a city using a Type I system to designate four fleets, each with eight subfleets. The police department, fire department, utilities group, and city administration could each be a separate fleet. The police might decide to further divide its fleet into subfleets, such as dispatch, tactical operations, detectives, north, south, east and west side patrols and supervisors. All the available police radios would then be assigned to one of the police subfleets, letting the police centralize their communications and control the type of users on a single system. Determining the exact fleet-subfleet hierarchy for a particular area is referred to as fleet map programming. The disadvantage of a Type I system is that the brief burst of data sent when a user transmits must contain the radio's ID, its fleet information, and the subfleet information as well. This is three times the amount of data a Type II system radio sends. Since the data capacity of Type I systems is limited, and the total amount of data increases with each user, Type I systems usually accommodate fewer users than Type II systems. Nevertheless, Type I systems are still in use.

Worked examples

Example 1 — a first encounter with Motorola Trunked Radio

Start with the simplest possible case. Write down what Motorola Trunked Radio claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Motorola Trunked Radio before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Motorola Trunked Radio ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Motorola Trunked Radio

In research: Motorola Trunked Radio appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Motorola Trunked Radio in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Motorola Trunked Radio is common in secondary-school and first-year university syllabi. It links to neighbouring topics Trunked radio systems, so understanding it makes those chapters shorter.
In everyday life: Look for Motorola Trunked Radio outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
