Radio frequency (RF)
To establish a stable wireless connection between the Vive Tracker and the dongle, the OTA
performance of Vive Tracker cannot downgrade to more than 3dB when an accessory is
attached to the Vive Tracker.
The following are recommendations for better RF performance:
Except for essential parts, such as the 1/4’’ screw, electric connection pad (which connects
with the Pogo pin), and related circuits of the electric connection pad, metal parts of the
accessory should keep at least 30mm distance away from the antenna to avoid OTA
performance reduction when the accessory is attached to Vive Tracker.
The figure below illustrates the “keep out” area where only nonmetallic parts of the accessory
should be inside (spherical radius=30mm and the center is antenna feed point).
