Transporters were teleportation devices similar to transmats used for instantaneous transport by the United Federation of Planets in a parallel universe. Transporters were used in Federation facilities as well as the vessels of their Starfleet. Transport was initiated by the vocal command "energize". (COMIC: Assimilation²)
When Delta IV was invaded by the Borg-Cyberman Fleet, the Deltan Prime Minister was, despite her protests, taken to a transporter where she and her entourage were transported safely to the secure command center.
Aboard the USS Enterprise (NCC-1701-D), the transporter was used to transport an away team consisting of Commander William Riker, Lieutenants Data and Worf as well as the Eleventh Doctor and his companions, Amy Pond and Rory Williams, to the surface of Cogen V. After witnessing the aftermath of the battle between the Borg and the Cybermen, the team was transported back to the Enterprise alongside a deactivated sentry drone which had been recovered by the Eleventh Doctor. Also taken aboard the ship were the dead bodies of a Borg and a Cyberman. (COMIC: Assimilation²)
