Despite its name, the teleportation grid does not actually "teleport" its users; rather, it encases them in a compressed slipstream field, transporting them from one position to another almost instantaneously. This happens much in the same way that a spaceship uses slipspace to travel between star systems - time passes for the individual, but due to the short distances involved it is negligible.
Both Installation 04 and Installation 05 were equipped with teleportation grids, allowing their Monitors to reach vital areas rapidly, and supervise their Sentinel charges. Onyx also possessed a teleportation grid. Although it is uncertain, it's likely that even Installation 00 had one.
Installation 04's teleportation grid, was used extensively during the course of the Battle of Installation 04. The Installation's Monitor, 343 Guilty Spark, first encountered John-117 outside of a Flood research facility, and used the Teleportation Grid to transport them to the Installation's Library, in order to retrieve the Activation Index. After the Index was retrieved, the Monitor used the grid again to transport the two of them to the Control Room to activate Halo's final weapon. During the Master Chief's efforts to neutralize the Installation's primary firing sequence, Cortana tapped into the teleportation grid, using his Mark V MJOLNIR armor’s fusion reactor to power a single jump, to a downed Covenant cruiser; however, Cortana's relative inexperience with the grid resulted in reorientation difficulties.
Installation 05Installation 05's teleportation grid was unavailable during the Battle of Installation 05 as it was being controlled by the Gravemind (formed beneath the Installation's Library facility) through the Installation's captured Monitor, 2401 Penitent Tangent. Managing to ensnare both John-117 and the Arbiter, it formed a tentative alliance with the two enemies in order to stop the rings activation - teleporting John-117 aboard High Charity, in orbit above the Installation, and the Arbiter near to the Control Room. The fact that it didn't, or couldn't, use the same grid to teleport its own Flood Combat Forms to those locations indicates that use of it is restricted to non-Flood life forms and constructs.
The Shield World Onyx also possessed a teleportation grid, used by Doctor Halsey to transport the Spartan IIs and IIIs to a safe area, away from Covenant activity. Later, she used it to send Spartan teams to disable a Sentinel production factory before transporting them again to the center of the planet, where a portal leading to a Micro Dyson Sphere was found. They then used the Sphere as a shelter from the Covenant army invading the facility.
Shield 0459 also contained a teleportation grid. In the Battle of the Apex, Professor Ellen Anders used it to escape The Apex into the surface of the Micro Dyson Sphere. Some time later, the UNSC also used a teleporter pad to transport the FTL Reactor of the UNSC Spirit of Fire to the Apex, in order to destroy the Shield World. The installation also possessed a variety of smaller teleporters.
- In co-op mode, when one person enters a loading zone, but the other person is separated, the other person will teleport with the exact animation as the Halo teleportation grid, even if the level is set on Earth.
- This also happens in Halo 3 when you flip inside a vehicle. It can be viewed easily in theater mode.
