Synchronization Range
In a location with no obstacles between the device and the user, the synchronization range is at least 10 m (30 ft.). Because data synchronization typically takes from 2 to 5 seconds, the devices should be installed in locations where users walk toward them.
TIP:
For best results, you should install the devices where user traffic passes from multiple directions. For example, you can install a device at a hallway intersection so it can synchronize data as users approach from all directions.
