Figure 6. Varying Proximity Thresholds

There are 10 proximity bins available to the application. Each bin represents a relative distance from the device.

The actual distance varies from implementation to implementation and is affected by many factors, including

housing, component tolerances, and RF environment. In Figure 6 (third on the left diagram), if the user put the

slave device (center) into proximity pairing mode with a bin of 3, the user would only be able to pair to one

device. All other devices would be outside of the pairing range.

Proximity pairing is a very powerful feature of ANT and is applicable in almost all applications, from simple

sensor pairings that occur occasionally to complex pairing environments such as gyms where pairing may be

done continuously with pieces of equipment in a crowded environment. It is seamless to the user and requires no

special hardware or UI to implement.

ANT NETWORKS

With up to eight independent ANT channels available on a single device, it is possible to connect ANT nodes to

many different types of network topologies. Sophisticated network topologies are just collections of ANT channels

and simple star networks. Figure 7 illustrates some of the possible network arrangements possible with ANT.
