SCALING REMOTE IOT USE CASES VIA SATELLITE NETWORKS
Internet of Things in urban areas and smart cities have relied on Wi-Fi and mobile networks for data exchange , but with the growing requirements of global coverage due to climate change , non-terrestrial network connectivity is making its way into IoT chipsets , says Dana Cohen Mizrahi at Sony Semiconductor Israel .
Non-terrestrial network connectivity is making its way into IoT chipsets , enabling connected devices and installations to be deployed anywhere . Some devices are being outfitted with stand-alone chips that can only connect to satellites , while others are using hybrid chipsets that support both terrestrial and non-terrestrial connectivity .
All satellite systems used to provide IoT , machine to machine communication services are based on either GEO or LEO satellites .
Legacy cellular network deployments cover more than 80 % of the population but less than 40 % of land and less than 20 % of Earth . Satellite connectivity has been used for years to provide ubiquitous coverage . However , its high cost has limited use for very specific scenarios , such as TV and broadcasting . In the IoT domain , satellite connectivity has always been a last resort alternative to terrestrial networks .
In recent years , the cost of non-terrestrial network solutions has dropped . As a result , it is economically feasible to use non-terrestrial network communication for IoT devices and start enable answer the need of communication everywhere .
Non-terrestrial network has developed into a communication channel of choice in various scenarios ,
