Summary

TLDRThe video script discusses the Avata 2 drone's radio signal, focusing on its unlocking features, speed, and FCC regulations. The Avata 2 operates on 5.8 GHz for video signal transmission, while the radio control and Motion controller signals use 2.4 GHz. It also utilizes the new O3 Air Unit protocol and can fly on three bands, depending on the location. In Europe, it uses 2.4 GHz and 5.2 GHz (referred to as 5.1 GHz in some regions), with a power output of 200 mW or 23 dBm. The video compares the performance of Avata 2 in Europe (CE mode) to its performance in the US (FCC mode), noting that the CE mode is quite efficient and not significantly different from FCC mode. The script also touches on the limitations imposed by DJI's firmware in Europe, the need for official U-space geographic zones, and the transmission of electronic identification and telemetry data. It concludes by mentioning that while the Avata 2's speed can be unlocked in certain modes, exceeding 19 m/s (68.4 km/h) is not compliant with standard scenarios, suggesting the use of the drone for specific operations with authorization.

Q & A

What is the main difference between Avata 2 and its predecessor in terms of radio signals?
-The main difference is that Avata 2, unlike its predecessor, operates on three frequency bands: 2.4 GHz, 5.2 GHz (referred to as 5.1 GHz in the script), and 5.8 GHz, depending on the location of flight.
Which frequency bands does Avata 2 use when flying in Europe?
-When flying in Europe, Avata 2 uses the 2.4 GHz and 5.2 GHz (or 5.1 GHz as mentioned in the script) frequency bands.
What is the power output of Avata 2 when operating on the 5.2 GHz band?
-The power output of Avata 2 on the 5.2 GHz band is 200 mW, which is equivalent to 23 dBm.
Why is the automatic transmission mode locked in the current DJI firmware when Avata 2 is flying in Europe?
-The automatic transmission mode is locked because the current DJI firmware does not allow manual changes, and there is no option to switch to manual mode as seen in the script.
What is the issue with the official U-space geozones in Italy?

😀 Introduction to Avata 2 Radio Signal and FCC Matters

The video begins with a welcome and an introduction to the topic of discussion, which is the Avata 2 drone's radio signal, its unlocking, speed, and related FCC issues. The speaker emphasizes that the content is informative and educational, not encouraging any actions that are not permitted in Italy and Europe. The main difference between the Avata 2 and its predecessor is highlighted, focusing on the radio signal. The Avata 2 operates only on the 5.8 GHz frequency for video transmission, while the radio control signal and Motion controller travel on the 2.4 GHz frequency. It also covers the use of the new OCUS in 4 protocol and how the Avata 2 uses three bands depending on the location, with specific details on the frequencies and power used in different regions. The firmware limitations when flying in Europe are also discussed, including the lack of manual transmission mode and the need for official U-space geographic zones, which are not yet available in Italy. The video concludes with a mention of the drone's electronic identification transmission and telemetry data.

😉 Avata 2's Performance in CE Mode vs. FCC Mode

The second paragraph delves into the performance comparison between the Avata 2's CE mode and the FCC mode. It is mentioned that the CE mode of the Avata 2 is quite efficient and not much different from the FCC mode. The use of the free AM Config system is discussed, noting that it does not work on the Avata 2 without the modified DJI app called Drone Twix, which enables FCC and is a paid app. Once activated, the app allows for FCC power on a greater number of channels. The paragraph also touches on the maximum capabilities allowed in Europe and the activation of the FCC mode to unlock the maximum speed. There is a mention of an unexpected speed increase even without explicitly unlocking the FCC mode and the mystery surrounding this occurrence. The speaker recaps that the CE mode of Avata 2 is comparable to the FCC mode of Avata 1, thanks to the OCUS in 4 protocol, antennas, and the 5.2 GHz band. It concludes with a note on the electronic identification and telemetry data transmission, emphasizing the importance of adhering to speed limits and regulations.

Keywords

💡Avata 2

Avata 2 refers to a specific drone model that is the subject of the video. It is distinguished from its predecessor by its radio signal capabilities and other technical features. The video discusses the differences in radio frequency bands used by Avata 2 compared to the previous model, emphasizing its enhanced performance and regulatory compliance in different regions.

💡Radio Signal

The radio signal is a critical aspect of drone operation, as it enables communication between the drone and its controller. The video explains that Avata 2 operates on different frequency bands (2.4 GHz and 5.8 GHz) for different purposes, such as video transmission and remote control, which is essential for understanding the drone's technical specifications and performance.

💡FCC Compliance

FCC (Federal Communications Commission) compliance is a regulatory requirement for electronic devices operating in the United States. The video discusses how Avata 2's firmware is locked to different transmission modes depending on the geographical region to ensure compliance with FCC regulations, which is crucial for legal operation of the drone.

💡Ocus Protocol

The Ocus protocol is a communication standard used by drones. The video mentions that Avata 2 uses the Ocus in 4 protocol instead of Ocus in 3, which is an upgrade that likely contributes to the drone's improved performance. This is significant as it indicates a technological advancement over the previous model.

💡Frequency Bands

Frequency bands refer to the specific ranges of frequencies used for wireless communication. The video details that Avata 2 operates on the 2.4 GHz and either 5.2 GHz or 5.8 GHz bands depending on the region, highlighting the importance of these bands for the drone's functionality and the need for regional compliance.

💡Geofencing

Geofencing is a feature that restricts drone operation in certain geographical areas, often for safety or regulatory reasons. The video points out that in Europe, Avata 2 requires official USOS (Unmanned Aircraft System Operations) geofencing data, which Italy has yet to provide, unlike other countries like France and Luxembourg.

💡Electronic Identification (EASA)

EASA (European Union Aviation Safety Agency) requires electronic identification for drones, which includes transmitting telemetry data. The video notes that when Avata 2 is in CE mode, it transmits the electronic identification, which is a regulatory requirement for drones operating in Europe.

💡Manual Mode (Acro)

Manual mode, also known as Acro mode, allows for more direct control over the drone's movements. The video discusses the speed limitations in this mode under CE regulations and notes an inconsistency where the drone sometimes exceeds the speed limit, which is a point of interest for drone enthusiasts.

💡Drone Twix App

The Drone Twix app is a modified version of a DJI app that enables FCC compliance features on Avata 2. The video explains that after activating this app, users can access FCC power levels on more channels, which is significant for those looking to maximize the drone's capabilities within regulatory limits.

💡Speed Limit

The speed at which a drone can fly is often regulated to ensure safety. The video mentions a speed limit of 19 m/s (68.4 km/h) under CE mode, which is a key consideration for drone pilots to operate within legal boundaries. It also discusses an anomaly where the drone may exceed this speed limit under certain conditions.

💡Telemetric Data

Telemetric data refers to the information transmitted by the drone about its status and performance. The video emphasizes that even if the drone is not in CE mode, it still transmits telemetric data, which is important for monitoring the drone's operation and ensuring it complies with regulatory requirements.
