What is an IoT gateway?

An internet of things (IoT) gateway is a physical device or software program that serves as the connection point between the cloud and controllers, sensors and intelligent devices. All data moving between IoT devices and the cloud passes through an IoT gateway, which can be either a dedicated hardware appliance or software program.

What is a gateway device & how does it work?

A gateway device can sometimes be used to preprocess that data locally at the edge before sending it to the cloud. In doing so, the device might deduplicate, summarize or aggregate data as a way of reducing the volume of data that must be forwarded to the cloud. This can have a big effect on response times and network transmission costs.

What is an example of an application gateway?

VoIP gateway is a good example of an application gateway. Cellular gateways can facilitate faster 4G and 5G speeds, which means that cellular data access can be used as a primary means of internet connectivity. Gateways used for this purpose need the ability to make cellular data compatible with the local network.

What is a VoIP gateway?

A VoIP gateway translates legacy analog landline voice and fax transmissions into digital VoIP protocol. IoT devices with their own protocols, such as Bluetooth, Zigbee, and LTE-M, may require certain gateway capabilities to connect to IT networks and servers.
