Name the different types of two-way radio topologies


Two-way radio systems offer a flexible solution for communication needs by allowing different configurations to be implemented based on the specific requirements of the organisation or user.

The topology, or the way the system is structured, can be customised to optimise communication efficiency and effectiveness. For instance, a point-to-point configuration can be established for direct communication between two specific locations, ideal for private conversations or quick exchanges of information. On the other hand, a star topology can be implemented to enable communication between multiple individuals or groups, with a central hub serving as the main point of contact.

This setup is useful for situations where coordination and collaboration among different teams or departments are crucial. Additionally, other topologies such as mesh or ring can be adopted, offering even more options to tailor the radio system based on the unique needs and constraints of the organisation or user.


Conventional two-way radio systems are the simplest and most basic type of system. In a conventional system, each radio is assigned to a specific channel. Users can only communicate with other users who are on the same channel. Conventional systems are typically used for low-bandwidth applications, such as voice communication and basic data transmission.

Trunked two-way radio systems are more complex than conventional systems, but they offer a number of advantages, including improved efficiency and capacity. In a trunked system, a group of frequencies is divided into a number of channels. When a user wants to communicate, they select a channel from the group. The system then dynamically assigns the user a frequency from the group, which ensures that there is no interference between users. Trunked systems are typically used for high-bandwidth applications, such as voice communication, data transmission, and location tracking.

Mesh two-way radio systems are a type of distributed network that allows users to communicate with each other indirectly, even if there is no direct line of sight between them. This is achieved by having each radio relay signals to other radios in the network. Mesh systems are typically used in applications where there is a need for reliable communication in difficult-to-reach areas.
