The Global Terminal, or the Global Trade Station (GTS) in Pokémon Diamond/Pearl, is the worldwide network over which players of all Generation IV and Generation V Pokémon games can trade Pokémon via the Nintendo Wi-Fi Connection. It is located in Jubilife City and Goldenrod City in Pokémon Diamond/Pearl/Platinum and in Pokémon HeartGold/SoulSilver, respectively. In order to access the Global Terminal, the player must have the Coal Badge in Pokemon Diamond/Pearl/Platinum. The Global Terminal is located in every Pokémon Center in Pokémon Black/White.
Inside, there is a large globe, called Geonet, on which players can indicate their location, and on which small dots representing players they have traded with will appear.
If the player talks with the woman at the counter, she will direct him or her into a room in which they can either put up a Pokémon to be traded or trade a Pokémon they own for one that has been put up for trade.
Pokémon searches, after being confined to one species that has been seen by the player, can be further narrowed down to level and gender of the Pokémon available. By level, players can search for and request Pokémon level 9 and under, level 10 and up, level 20 and up, and so on to level 100, or they can search for Pokémon of any level. Gender is similar, with the player being able to search for male, female, or either gender of the selected Pokémon.
Pokémon offerings are similarly governed, as the requested Pokémon in return cannot be any Pokémon that the player has not seen. Unfortunately, Pokémon that are offered cannot be bargained, as the player has to choose one Pokémon he or she wants for it, instead of having a more flexible list.
Like normal, inter-game trades have been since Generation II, a Pokémon can also hold an item when being offered or traded. This may add incentive for a player to trade his or her Pokémon for a Pokémon that they already own, instead of just trading to complete the Pokédex, in order to get the item attached. Just the same, Pokémon that evolve after a trade will do so.
