60 Chapter 3 Aircraft
The transmission data is based on the remote controller and comes from test data, and the
test environment and conditions are different, and the data may be different.
The transmission range is for reference only. During use, please pay close attention to the
quality of the image transmission signal. When the image transmission signal is weak,
reduce the flight radius in a timely manner. For more information, see “
Notification Bar” in Chapter 6.
Please note that the maximum communication distance of the included remote controller
is 15 kilometers. To achieve a 20-
kilometer communication distance with the aircraft, a
ground device with stronger communication capabilities is required.
Information Of Communication Frequency Bands for Aircraft
The communication frequency bands of the Autel Alpha comply with regulatory requirements
worldwide. The relevant certified frequency bands are listed in the table below.
In actual use, after power-on and paired the aircraft and the remote controller, the Autel
Enterprise App in the remote controller will automatically determine the location based on the
GNSS information received by the aircraft. It will then automatically select the radio
communication frequency band that complies with local regulations for the specific country or
region.
After the aircraft is paired with the remote controller, the frequency bands between them
will be automatically controlled by the Autel Enterprise App based on the geographical
information of the aircraft. This is to ensure compliance with local regulations regarding
frequency bands.
Users can also manually select a legal image transmission frequency band. For detailed
instructions, see “6.5.4 Image Transmission Settings” in Chapter 6.
Before flight, please ensure that the aircraft receives a strong GNSS signal after powering
on. This allows the Autel Enterprise App to receive the proper communication frequency
band.
When users adopt visual positioning mode (such as in scenarios without GNSS signals), the
wireless communication frequency band between the aircraft and remote controller will
default to the band used in the previous flight. In this case, it is advisable to power on the
aircraft in an area with a strong GNSS signal, then start flight in the actual operational area.
