Beacon Signals
Beacons are continuously transmitted carrier waves (modulated or unmodulated) along with
identification at regular intervals. Beacons can be directional or non directional, used for navigational purpose mainly in maritime and aviation fields (Now it's GPS !), as a frequency standard and  a guide to observe the band opening (propagation) condition. An operator can easily judge the opening of the radio propagation to a particular region by monitoring the existence and  strength of the beacon signals.
