Adaptive Network Topology
Adaptive Network Topology is a proprietary (but open access) multicast wireless sensor network technology designed and marketed by ANT Wireless. It is primarily used for sports and fitness sensors.
It defines a wireless communications protocol stack that enables hardware operating in the 2.4 GHz ISM band to communicate by establishing standard rules for co-existence, data representation, signalling, authentication, and error detection. It is conceptually similar to Bluetooth low energy, but is oriented towards usage with sensors.
