Internet of things

IOT is just "Devices on the Internet".
So the only requirement is that they talk to the Internet. And you can use any technology (standard or not) to talk on the internet, as long as it's TCP/IP. i.e. Microwaves, InfraRed, etc. (See also the Internet Zero 'standard')(2) Is there a dedicated standard for IoT? Like Wi-Fi has 802.11, Cellular has 3GPP, Bluetooth has 802.15, etc. : IOT (reddit.com)
