Peter Thornycroft: Wi-Fi access for the Internet of Things can be complicated

Most large enterprises run remarkably secure WLANs. They minimize open-authentication access points – and those use captive portals – and implement WPA2-enterprise authentication and encryption protocols, which are very difficult to crack.

However, well-configured access points inhibit the growth of the Internet of Things (IoT) over Wi-Fi. The emerging IoT model (from the residential world) connects headless sensors over wireless connections to a cloud service that manages them and collects traffic. This service then offers a portal for analytics and smartphone-based user-control.
