WiFi modem/hotspot of a phone, or a laptop. If WiFi relay of the video from the ground station
is desired, it is recommended to use a 5.8GHz WiFi modem.
⚫ Interference by Bluetooth device
Bluetooth operates on 2.4GHz in frequency hopping mode. So a Bluetooth mouse, Bluetooth
joystick, or any Bluetooth device that is actively working and next to ground station will
interfere the reception of downlink video. Please avoid using Bluetooth device when operate
a drone with 2.4GHz wireless link.
⚫ Interference by wireless device in co-existence
Another wireless device that operates on bands close to 2.4GHz and the device is placed close
to the drone’s 2.4GHz wireless module can interfere the drone’s wireless link. For example,
some drones have both LTE link and point-2-point wireless link. Particularly, the LTE
operating on 2.3GHz band can be a problem. If the antenna of the LTE module is placed close
to the antenna of the 2.4GHz point-2-point wireless module, the receiver of 2.4GHz module
can be saturated by the LTE signal when it is transmitting. Thus, the range/performance of the
2.4GHz module will be significantly degraded.
⚫ Interference by HDMI
When HDMI source/cable is close the antenna of 2.4GHz wireless modem, the HDMI
source/video will interfere the 2.4GHz wireless signal (including WiFi).

It is recommended that install the antenna at least 25cm away from the HDMI source/cable.
A good shield HDMI cable can be a resolution too. The following shield HDMI cable uses
360-degree shield termination, which is recommended practice.
