What is Gateway?

Gateways are devices that make use of Internet of Things (IoT) technology to connect to a blockchain system or related network infrastructure. Most IoT network devices are generally inhibited by poor battery life, limited computing power, restricted communication bandwidth, and other criteria that affect performance. Gateways were designed to help combat these inefficiencies and can be made up of any number of devices that possess the capability to run a network themselves. Examples of gateways include a mobile phone connected to various wearable devices, a smart car linked by multiple in-car devices, or a 5G base station connected to a multitude of IoT devices.
