### Wi-Fi Radio Location

The Control Hub has an embedded Wi-Fi radio for wireless communication. The antenna is located towards the top of the Control Hub itself. The graphic below shows the location of antenna.

{% hint style="warning" %}
DO NOT put a battery or other Wi-Fi blocking object on top of the Control Hub. This can lead to higher ping times for communication between the Control Hub and the Driver Station.
