Which of the following describes a linked repeater network?

• A. A network of repeaters that use different frequencies
• B. A network of repeaters in which signals received by one repeater are transmitted by all the repeaters in the network
• C. A system that operates only on simplex channels
• D. A series of repeaters that only receive but do not transmit

Answer: (B)

A linked repeater network is characterized by the ability of multiple repeaters to work together, enabling communication over greater distances than a single repeater could provide. This network functions by allowing one repeater to receive a signal and then retransmit it to other repeaters within the network. This means that signals coming into one repeater can be sent to all linked repeaters, effectively expanding the coverage area for users.

The advantage of such a system is that it facilitates seamless communication across a broader range, which is particularly beneficial in emergency situations or events where reliable communication is crucial. As a result, this interconnected functionality is what distinguishes a linked repeater network from systems that operate on different frequencies, or from those that do not transmit signals but only receive.

In contrast to simplex systems, which only allow for one frequency channel for transmitting and receiving, linked networks involve repeaters working together effectively, enhancing communication capabilities. Overall, the essence of a linked repeater network lies in its collaborative operation, amplifying signal reach and facilitating communication across vast areas.
