There now are more IoT devices(connected cars, smart home devices, connected industrial equipment) than phones, laptops, and computers connected to communications networks, says IoT Analytics. There are 21.7 billion active connected devices worldwide, and IoT appliances now represent 11.7 billion (54 percent) of those connections.
By 2025, it is expected that there will be more than 30 billion IoT connections, IoT Analytics says.
The vast majority of those devices will be connected to a local area network of some type, including short-range connectivity such as Bluetooth to premises systems such as Wi-Fi. Perhaps a quarter of all connections will use a public network of some type.
