signal relay
Transmission handoff station
A signal relay is a device that receives, amplifies, and retransmits a signal to extend its range or strength.
Radio towers act as signal relays for broadcast transmissions.
In electronics, a relay is a switch activated by an electrical signal, allowing one circuit to control another.
The term applies broadly to any system that passes information along a chain: The message reached headquarters through a series of signal relays.
