===Range===
During the 22nd century, standard Earth transporter systems had a range of 10,000 kilometers; however, by the 24th century, standard transporter systems maximum range was about 40,000 kilometers, though a special type of transport, called subspace transporter|subspace transport could beam over several light years. (ENT|Rajiin; TNG|A Matter Of Honor|Bloodlines) Many 24th century starships were equipped with an emergency transporter system, but these only had a range of at best ten kilometers. (VOY|Future's End)

Although having a maximum range of about 40,000 kilometers, some conditions adversely affect the effective range.  In at least one instance &ndash; due to missing components of Voyagers primary computer systems, &ndash; the starship ''Voyager'' had to be within 500 kilometers of a planet's surface to use transporters on Kathryn Janeway and the hologram character Leonardo da Vinci. (VOY|Concerning Flight)
:''For context, 500 kilometers above the surface of Earth would place the ship inside the ionosphere.''

The maximum range of a transporter differs per species, depending on what kind of technologies they've used to build it. The transporter with the longest known range is that of the Sikarians, with a range of about 40,000 light years; however this was due to their planet's large quartz mantle which amplifies their transporter signal. Because of this, Sikarian transporter technology works only on Sikaris|their planet. (VOY|Prime Factors)

Gary Seven's mysterious sponsors possessed transporter technology with a range of at least a thousand light-years according to Spock. Scotty later noted that Seven's beam was so powerful it fused all of recording circuits, and therefore he could not say exactly how far it transported Seven, or even whether it transported him through time. Exactly how they achieved this effect remains unknown, since there has been no subsequent contact with them, and they hide their entire homeworld in some fashion. There were, however, other indications that their technology was considerably advanced beyond what that of the 23rd century Federation. (TOS|Assignment: Earth)

Dominion transporter technology, enhanced with a homing transponder, was said to have a range of ''at least'' three light years. (DS9|Covenant)
