ANT devices support up to 8 multiple independent ANT channels, where any channel can operate as a master or slave on a given node. Message relay from node to node becomes easy. There is no requirement for a coordinator or network level master for complex topology accomplishment. A moderate crystal suffices as there is no precise timing synchronization requirement for ANT network establishment.
