relay stations
Transmission handoff points
Relay stations are intermediate points in a communication or transportation network that receive and retransmit signals, messages, or goods.
In broadcasting and telecommunications, they amplify and forward radio, television, or data signals to extend coverage: The mountain relay station boosted the signal to the valley below.
Historically, relay stations provided fresh horses for stagecoach travelers.
The term applies anywhere something is passed along a chain rather than sent directly.
