A subspace beacon was an omnidirectional repeating signal transmitted in the subspace realm.
In 2153, Tellarite bounty hunter Skalaar deployed such a beacon as a decoy from the Tellarite shuttle he captained. Its warp signature was tracked by Enterprise NX-01 but the device was ultimately destroyed by that starship. (ENT: "Bounty")
In an alternate timeline, Kathryn Janeway activated the subspace beacon in her Starfleet combadge when she and Tom Paris were thrown back in time on an unknown Class M planet. The senior staff of the USS Voyager used the beacon to locate and attempt to retrieve Janeway and Paris. (VOY: "Time and Again")
