In summary, ANT is an adaptive isochronous ad-hoc wireless protocol and silicon solution that operates in the 2.4GHz frequency spectrum, suited for low data rate sensor network topologies in personal area networks. An ANT node is a device, it can be a sensor or a display, and can support up to eight independent channels. An embedded serial message protocol composed of fifty messages enables the definition of radio operation and data transfer. An ANT channel consists of a master node and a slave node and can support peer to peer, star, tree, shared or asynchronous network topologies. Each message is comprised of 8 bytes of user defined data. Data messages can be transmitted in one of three formats; broadcast, acknowledged or burst. ANT has several mechanisms to protect against interference, including adaptive channel synchronization, frequency agility, and a proximity search function. ANT+, an interoperable application layer supporting fitness, sport and health device solutions has also been completely defined offering reference designs for ANT implementations, such as heart rate, cycling sensors of fitness equipment interfaces, in this area. Device profiles for 20 device types are currently available and technical access is free of charge through the ANT+ Adopter zone. More about this option can be found on www.thisisiant.com.
