Gateway (telecommunications)
A gateway is a piece of networking hardware or software used in telecommunications networks that allows data to flow from one discrete network to another. Gateways are distinct from routers or switches in that they communicate using more than one protocol to connect multiple networks[1][2] and can operate at any of the seven layers of the OSI model.
The term gateway can also loosely refer to a computer or computer program configured to perform the tasks of a gateway, such as a default gateway or router, and in the case of HTTP, gateway is also often used as a synonym for reverse proxy.[3] It can also refer to a device installed in homes that combines router and modem functionality into one device, used by ISPs, also called a residential gateway.[4][5][6]
Network gateway
A network gateway provides a connection between networks and contains devices, such as protocol translators,
On an
In enterprise networks, a network gateway usually also acts as a proxy server and a firewall.[7]
On Microsoft Windows, the Internet Connection Sharing feature allows a computer to act as a gateway by offering a connection between the Internet and an internal network.[8][9]
Internet-to-orbit gateway
An Internet-to-orbit gateway (I2O) connects computers or devices on the Internet to computer systems orbiting Earth, such as satellites or crewed spacecraft. Project HERMES, run by the Ecuadorian Civilian Space Agency, was first to implement this kind of gateway on June 6, 2009.[10][11] Project HERMES has a maximum coverage of 22,000 km and can transmit voice and data. The Global Educational Network for Satellite Operations (GENSO) is another type of I2O gateway.

IoT gateway
An Internet of things (IoT) gateway provides the bridge (protocol converter) between IoT devices in the field, the cloud, and user equipment such as smartphones. The IoT gateway provides a communication link between the field and the cloud, and may provide offline services and real-time control of devices in the field.[15][16]
