Earth Stations/Teleports - Hub.
The user organization generally needs a large earth station to serve as its central coordinating point and to provide access to other networks, such as the corporate WAN, the Internet, or the Public Switched Telephone Network (PSTN). This is a make-vs-buy decision, because the user has the option to use a public facility called a teleport, which is operated by a service provider.
Teleport.
A teleport is a telecommunications business that provides services to local users. Today, thanks to readily available high-quality wideband fiber circuits, it is also possible to use a teleport in another city.

A teleport may provide other services besides large antennas and baseband equipment services:
- Remote site support, such as satellite news gathering.
- Network operations.
- Program origination and edit.
