Spawn Beacon (Squad Beacon, “bacon”) can be deployed in any location with clear sky above. Spawn Beacon automatically becomes available to squads with at least two squad members. Spawning players are deployed via drop pod.
Spawn Beacon becomes available to players at BR10 (not 100% sure on this one).
Upgrading the Spawn Beacon reduces the spawn cooldown, but even at maximum rank the respawn timer remains considerably longer than for other spawn options. Spawn Beacon can be upgraded in the “Leadership Certifications”, located in the “Social” menu. Upgrading reduces the spawn cooldown.
Spawn Beacons are often placed by Light Assaults at tallest points of bases, such as antennas.
