CAP (Compact Application Protocol) is Arch Rock’s proposal to run ZigBee Application Profiles such as Smart Energy and Home Automation over a standard Internet Protocol (IP) stack. CAP brings the benefits of the ZigBee Application Profiles to a whole new set of devices on diverse networks, including Ethernet, Wi-Fi, and HomePlug, while preserving the resource efficiency and compactness crucial to devices running on IEEE 802.15.4 low-power radio.
