A customer saw our real test video about the 2 watts Power Amplifier 27km transmisor ne receptor ar vídeo inalámbrico ya'bu̲ ntsoni ngatho. He placed an order for this equipment. He hoped we would also bring the transmitter to the top of the mountain and the receiver to the seaside for testing before shipment. We have done our best to meet the needs of the customers. So we did it and created today’s video. If you want to learn about the actual transmission effect of long-range HD 1080P wireless video transmission, as well as how to operate it. Please keep watching.
Let’s begin by looking at the test location and distance on Google Earth. Search Meishajian, which is located on Shenzhen’s third highest peak, for no obstructions and simulate the situation of an aircraft with a transmitter in the air, ensuring that the test is within the line of sight. There are many high-rise buildings in a coastal city like Shenzhen. Finding a test environment with a line of sight and a distance of 30 kilometers is difficult. A T-shape is formed from here to the seaside of Nan’ao. Our receiving station is on the beach, and we can see the top of the transmitter from a distance of 27 Kilómetros.
We used the good distance tool to determine that the distance between the transmitter and the receiver is nearly 27km. In the following video, we can see from the receiver’s web UI page that the current transmitter to receiver distance is 27390 metros.
Now let’s take a look at the situation of the transmitter on the mountain. The transmitter, IP network camera, and battery are placed on the rock. The trekking pole and red bubble belt make a red flag, which is fluttering in the wind so that the picture on the receiver screen is not static, it can be observed whether the wireless transmission video is smooth. The receiver is on the other side of the sea. The black transmitter is connected to two 30cm height transmitting antennas, the left part is the IP network camera, which is connected to the transmitter with a network cable, and the right part is a 12V battery, which powers the transmitter and the IP network camera.
Please try to position the transmitter and receiver vertically while transmitting. The signal strength will then be strong. Allow me to turn the transmitter and receiver in my hand, and the receiver monitor video will begin to move. The receiver will determine whether or not the video is smooth.
Now let’s take a look at the picture of the receiver.
The receiver is connected to the computer through the network cable. We can use the RTSP player on the computer and see the smooth picture directly.
We can also enter 192.168.8.11 in the browser to open the setting page of the receiver. On this parameter setting page, we can see various parameters of the current transmitter and receiver. An important parameter in this table is the distance and the signal strength. Now we can see that from the current transmitter to the receiver distance is 27390 metros.
In the computer’s RTSP player, we can see that the wireless video transmission picture from the mountain transmitter has been kept very smooth, and the little red flag and the grass are fluttering in the wind without any lag, frozen, mosaico.
We are using an IP network camera to test, if your camera has HDMI 1080P, 4K HD, Sdi, AHD, or CVBS output, we also can add an encoder to the transmitter, connect your video output, and send out the IP living streaming to the transmitter. Ja ar receptor, output the video to a computer through a network cable, or to a network video recorder.
It can be seen that the picture is very smooth,
Here we continue to play the videos recorded by the transmitter and receiver on the computer, and we can also answer some questions that some clients care about and always asked.
Two-Way full duplex Wireless Video Data Audio Transmission
'Me̲t', this set of wireless video data transmission transmitters and receivers is a two-way full duplex transmission system, it is like setting up an invisible wireless network in the air, two computers can be connected, and ping can be used in the computer’s cmd command state. In addition to transmitting video, data and audio can also be transmitted.
Power Amplifier options 2W, 5W, and 10W to support longer distance
Mfe̲tsi, if you want to support longer distances, we can achieve longer distances by changing different amplifiers. Ngu, 300mW, 2 Vatios, 5 Vatios, 10 Watts power amplifier, the corresponding transmission distance is 7 km, 15 km, 30 km, 80 km, 100 km, the farthest can be transmitted to 150 km, we also have a 110 km The actual test video. If you are interested, I can also edit it and upload it for everyone to watch.
Up to 150Km, 4 times of English Channel Width
Tercero, what is the concept of supporting up to 150 Kilómetros? It is equivalent to 93 millas. The UK is separated from Europe by the English Channel, and its width is only 35 Kilómetros, that is, 150 kilometers is equivalent to the width of 4 times English Channels. It can also transmit high-definition videos with good signals.
Descarga video, UART Data TX RX,
'Re̲t', if you need to control the PTZ camera, the receiver can also send control commands to adjust the direction and movement of the camera. This set of Wireless video data transmission transmitters and receivers also has three RS232 data interfaces, which can transmit various commands and data, and even connect with the drone’s flight control to remotely operate the drone.
Aes 128 to protect video data safety
Fifth, this wireless video transmission device also supports aes128 for video encryption and decryption, so you don’t have to worry about your video, not safety, or being intercepted by others.

- If your area has a DVB-T or DVB-T2 digital television signal, ar TV frequency range is 170-860Mhz, it has including 800Mhz, so choose 1.4G is better.
- Because the GPS antenna receives the GPS signal and the GPS direction on the drone is up, our transmitter antenna is pointing down to send the signal to the ground. Komongu ar nt'uni, the 1.4G frequency effect on GPS is negligible.
The package size is 125 x 23 x 11 ar cm. Be̲xu bruto：3.72KG， Be̲xu ar volumen：7.5KG
Here is the full set picture.
Regarding frequency hopping, the engineer has some suggestions for you.
- As the system frequency range is 20Mb, if your bandwidth is chosen 20Mb, then it can not hop (only one point). If the bandwidth is chosen 10Mb, then you have two points to hop, if the bandwidth is chosen 5Mb, then you have 4 points to hop.
- If 1410Mhz has jammed, then 1420Mhz also has jammed, as the frequency is too close.
- When hopping frequency, the data or video transmission will be disconnected, and your video will be frozen.
- Ar ora normal, it is better to choose hopping is NOT.
- If your transmission distance is less than 15~22km, then we have another option to choose from, the frequency has 110Mb, and even if you choose 20Mb bandwidth, pe̲ts'i 5 points to choose from for frequency hopping.
If you need to support S.bus, then please tell us before shippment, and we will modify our RS232 to TTL.
Our TX900 has three RS232 ports. If you need it to support S.bus, just need plus one small converter from S.BUS to RS232 is ok. ( Mini SBUS Conversion Module Uart to Sbus, Sbus to Uart ).
Please tell us if you need sbus port before delivery. Our engineer will modify the D2 port from RS232 to Sbus.
RSSI wireless link status data requires customers (such as flight controllers) to manually send AT commands to obtain it. It can be obtained in two ways:
- Configure UART3 (data port 3rd) as an AT command serial port, and then send AT commands through UART3 (D3) to obtain. https://ivcan.com/change-d3-from-transparent-serial-port-to-at-command/
- Update the firmware version 1.5.1 wa mäs xi ngu, so that there will be an additional TCP server inside for customers to access through TCP to send AT commands to obtain the wireless status.
- The LED light is used to indicate the wireless connection status (ngu, if the wireless link is disconnected, the light will go out), and there is no dedicated external pin to notify the customer flight control.
Or see the UART AT command list nuwa.
or see https://ivcan.com/how-to-get-the-rssi-and-snr-on-the-drone-transmitter/
- The serial port of our wireless video transmission is transparent, and no data is actively sent to the flight controller. This is controlled by the ground station.
- It won't send the failsafe command, but you can see the link status light from the signal indicator.
- Here is the link status signal strength indicator means
- Not Bright: Indicates that the wireless link of the module is not connected
- Xí nthe̲ni: Indicates that the wireless link of the module has been connected, but the wireless signal strength is very weak
- Orange: Indicates that the wireless link of the module has been connected, and the wireless signal strength is medium
- Xí: Indicates that the wireless link of the module has been connected, and the wireless signal strength is very strong
- We understand that you hope to have this function, If aircraft loses signal during flight it will not return to home because flight controller will not understand that rc link is lost.
- You need to see the link status LED light, if it is Orange or Red, you should control the plane back in advance.
- You also can get the RSSI at the below windows
Please check the upgrade firmware setps, download the latest upgrade firmware at the below link.

At the normal usage, one node as the transmitter, another node as the receiver. If you need to support long range or over a mountain top, like the below picture, Hä, please buy 3rd nord as the reapter.
You just need to put the 3rd node in the middle and set the 3rd node be a 2D3U then ok.
How to set 3rd node be 2D3U?

If you get result is 6602, then it is 15km Versión.
If you get result is 6603, then it is 30km Versión.
4K video is supported.
4K video stream generally has more than 8Mbps, and 1080P video generally has more than 2M, so the distance of our wireless video transmission when transmitting 4K video will be shorter than that of 1080P.
In one word, the higher the definition of the video, the shorter the transmission distance.
The video compression is smaller, and the transmission distance is supported farther.
In the process of video transmission, if there is data loss, the picture will appear mosaic or stagnation, freeze and other phenomena.
There will be a limited number of retransmissions at the wireless link level (Majwäni, data errors will also occur if the situation is not good). The upper-layer application on the end will not be aware of it, nor will it ask the sender to retransmit.
If the signal of the wireless link is not good at a certain point after the distance is extended, and there are always bit errors, it is impossible to design it to be retransmitted all the time, so that the end user experience will be very poor.
The wireless link layer has a limited retransmission mechanism. We have tested the tcp protocol for transmission at the video transmission layer (trying to retransmit on the upper layer through the tcp protocol), but the test found that there is no obvious improvement, and it will also lead to uncontrollable delays.
- The heat generated by the aircraft side is much larger than that of the ground side. If the fan is running, check whether the air inlet and outlet of the lower fan (the positions of the heat sinks at both ends) are blocked
- Try changing the power supply of the air unit transmitter from 24V to 12~18V (the transmit power will be reduced to about 35~36DB)
- Slightly reduce the transmit power of the aircraft by the below AT commands: AT^DSSMTP="23" Reboot after setting
Ar nt'a̲ni: Are these settings maximum power of the module? (24 dBm)
Respuesta: 24dBm is the maximum output power of the link Module, and the gain of the PA (about 14dBm) needs to be added. The actual transmission power after the 24V power supply PA output is about 38dBm.

The difference between the air unit (transmisor) and ground unit (receptor) is two points:
One is the device type: Air unit (transmisor) is the Nodo nthogi and the ground unit (receptor) is the central node.
Two is the rate ratio of the downlink and up link. Over 30km, the best rate ratio is 4:1 o 3:2.
If you don't want to connect the receiver ethernet cable directly to the computer. Then it is not easy to access the receiver at your local network.
Here is two solutions for you.
1. Add the IP address of the 192.168.1.x network segment on the PC side (the PC can be configured with multiple network segment IP addresses)
2. Modify the IP of the wireless video data receiver from 192.168.1.12 to the address of the 10.220.20.x network segment to meet your local network.
For further questions and solutions, please talk with your local area network workmate or engineer, our receiver is like a computer with IP address, it should keep the network segment IP address at the same, ngu, 192.168.1.xxx.
- Hä, there are three solutions to do that.
- TX900 has three data ports. Distinguish through different transparent serial ports, such as D2 to control relay aircraft and D3 to control mission aircraft. The disadvantage is that the TX900 receiver needs to be connected to two serial ports to send instructions separately.
- Use the same transparent serial port to send data in bulk, and then add layer protocols (such as header information) to the data to distinguish which aircraft should receive and process the data. The disadvantage is that the processing of sending and receiving data is complicated.
- Or use two receivers: One receiver is for the mission plane (transmisor), and another receiver is for the repeater drone. The connection and operation are easier.

Optional TX900B for some clients need frequency hopping function.
- TX900B-2W supports the frequency range is 1420~1530MHz, and there is 110Mb bandwidth to use. (800Mhz frequency range does not support this 110Mb bandwidth)
- The customer can set the working bandwidth as 1.4M/3M/5M/10M/20MHz (However 1.4M/3MHz may not be suited for video transmitting). Then TX900B-2W can work in FHSS mode (Espectro ensanchado ya salto frecuencia) and the central working frequency will be automatically selected by the system and may do frequency hopping (between 1420~1530MHz) during its working.
- Customers can also plan to use the frequency channels in the whole 1420~1530MHz and set the device to work in the fixed frequency channels too.
- TX900B-2W supports the longest distance at 22km.
- Except for the frequency range supported and the longest distance, the physical appearance, interfaz ar, UI, operación, ne bí nja'bu̲ bí sucesivamente, the TX900B-2W is the same as the existing TX900B-15km-2W.
- TX900B-2W only supports a frequency range is 1420~1530MHz, it does not support 800MHz and 2.4GHz frequency ranges.
- There are two versions, TX900B-2W-15km, and TX900B-2W-22km.
- As the TX900B-2W frequency range is 110Mb, so if you configure the working bandwidth as 10Mb, then you will get 11 points to hopping.
- TX900B supports 110Mb bandwidth for frequency hopping and only has three transmission ranges optional, 22km, 55km, ne 150km.
