To konw more about Low-altitude aviation economy and walkie talkies

In the low-altitude economy, the selection of frequency standards is crucial for communication between drones and other low-altitude flying vehicles. Here are some key frequency standards and related information:

Major Frequency Standards

1. 1430-1444 MHz:

- This frequency band is specifically designated for telemetry and downlink information transmission for civil unmanned aerial vehicles (UAVs). The use of this band ensures effective data transmission during drone flights.

2. 2400-2476 MHz:

- This band is widely used for short-range wireless communication, including control and data transmission for drones. It is a common frequency range for many consumer-grade drones.

3. 5725-5829 MHz:

- This band is also utilized for radio communication of drones, particularly in applications that require higher data transmission rates.

4. Millimeter Wave Band (30 GHz - 300 GHz):

- The millimeter wave band provides a wide bandwidth suitable for high data transmission rates, especially in 5G and future 6G networks, supporting precise control and rapid data exchange for low-altitude flying vehicles.

5. 5G-A (5G Advanced):

- As an evolution of 5G technology, 5G-A can utilize millimeter waves and sub-6GHz bands to provide low-latency, high-bandwidth communication capabilities for drones in the low-altitude economy.

Application Background

1. Integration of Sensing and Communication:

- The integration of communication and sensing technologies in the low-altitude economy requires efficient utilization of spectrum resources to achieve dynamic scheduling in time, frequency, and airspace.

2. Regulation and Management:

- These frequency bands are typically subject to strict regulation to ensure the stability and safety of communications while avoiding interference and conflicts.

3. International Coordination:

- As the low-altitude economy develops, international coordination on spectrum resources becomes increasingly important to facilitate global market expansion.

By rationally planning and effectively utilizing these frequency standards, the development of the low-altitude economy can be supported, enhancing the operational efficiency and safety of drones and other flying vehicles.
