# 텔레메트리 라디오/모뎀
|
|
|
|
Telemetry Radios can (optionally) be used to provide a wireless MAVLink connection between a ground control station like _QGroundControl_ and a vehicle running PX4. 비행중인 기체의 매개변수 변경, 실시간 텔레메트로 통신, 임무 변경 등의 작업을 수행할 수 있습니다.
|
|
|
|
PX4는 다양한 텔레메트리 라디오 타입을 지원합니다:
|
|
|
|
- [SiK Radio](../telemetry/sik_radio.md) based firmware (more generally, any radio with a UART interface should work).
|
|
- [HolyBro SiK Telemetry Radio](../telemetry/holybro_sik_radio.md)
|
|
- [RFD900 Telemetry Radio](../telemetry/rfd900_telemetry.md)
|
|
- [ThunderFly TFSIK01 Telemetry Radio](../telemetry/tfsik_telemetry.md)
|
|
- <del>_HKPilot Telemetry Radio_</del> (Discontinued)
|
|
- <del>_3DR Telemetry Radio_</del> (Discontinued)
|
|
- [Telemetry Wifi](../telemetry/telemetry_wifi.md)
|
|
- [J.Fi Wireless Telemetry Module](../telemetry/jfi_telemetry.md)
|
|
- [Microhard Serial Telemetry Radio](../telemetry/microhard_serial.md)
|
|
- [ARK Electron Microhard Serial Telemetry Radio](../telemetry/ark_microhard_serial.md)
|
|
- [Holybro Microhard P900 Telemetry Radio](../telemetry/holybro_microhard_p900_radio.md)
|
|
- CUAV Serial Telemetry Radio
|
|
- [CUAV P8 Telemetry Radio](../telemetry/cuav_p8_radio.md)
|
|
- XBee Serial Telemetry Radio
|
|
- <del>[HolyBro XBP9X Telemetry Radio](../telemetry/holybro_xbp9x_radio.md)</del> (Discontinued)
|
|
|
|
PX4 is protocol compatible with [SiK Radio](../telemetry/sik_radio.md) and will generally work out of the box (though you may need to change/use an appropriate connector).
|
|
|
|
WiFi 원격 측정은 단거리에서 데이터 속도가 빠르며, FPV/비디오 피드를 보다 쉽게 지원할 수 있습니다.
|
|
WiFi의 이점은 차량용 라디오 장치 하나만 구입하면되는 점입니다 (지상국에 이미 WiFi가 있다고 가정).
|

|
|
PX4 does not support connecting an LTE USB module to the flight controller (and sending MAVLink traffic via the Internet).
|
|
보조 컴퓨터로 LTE 모듈을 연결하여 보조 컴퓨터에서 비행 제어 장치로 들어가는 MAVLink 데이터 흐름을 통제 가능합니다.

## Allowed Frequency Bands
|
|
|
|
Radio bands allowed for use with drones differ between continents, regions, countries, and even states.
|
|
You should select a telemetry radio that uses a frequency range that is allowed in the areas where you plan on using the drone.
|
|
|
|
Low power [SiK radios](../telemetry/sik_radio.md), such as the [Holybro Telemetry Radio](../telemetry/holybro_sik_radio.md), are often available in 915 MHz and 433 MHz variants.
|
|
While you should check applicable laws in your country/state, broadly speaking 915 MHz can be used in the US, while 433 MHz can be used in EU, Africa, Oceania, and most of Asia.
