repeater model for one-way video data transmission unidirectional
For the one-way COFDM Video Data Transmission repeater, we recommended the model वीकैन 1886, Which has built-in RX (प्राप्त करें) and TX (transmit) two functions, it can get video and data from your transmitter, and send video and data to your receiver, This module has two frequencies, one frequency is as the receiver frequency, it is the same with your transmitter, another frequency is as the transmitter frequency, it is the same with your receiver.
We also can customize the repeater/relay for you. हस्तक्षेप से बचने के लिए, we also add the two filters, नीचे दी गई तस्वीर की तरह.
Repeater/Relay solution for two-way video data transmission bidirectional
TX900-10W PA introduction and solution as the Drone repeater
TX900-10W PA power amplifier supports drone repeater and FHSS function. Let me introduce the details below.
1. TX900 consists of a core modem (वीकैन1681, two-way wireless video, and data link module) and a 2-watt, 5-वाट, or 10-watt RF power amplifier inside. (a core modem and 2-watt PA inside picture)
2. There are two versions of the core modem (the same hardware with different SOC firmware): the star wireless network version and the Mesh wireless network version.
| भाग संख्या | आवृत्ति बैंड(मेगाहर्ट्ज) | नेटवर्क प्रकार |
| K150 | 1420~1530 | स्टार वायरलेस नेटवर्क संस्करण.(पी2पी, P2MP) इसका उपयोग पॉइंट-टू-पॉइंट ट्रांसमिटिंग के लिए किया जा सकता है, बिंदु-से-एकाधिक बिंदु संचारण, और एक-नोड रिले संचारण. दो बिंदुओं के बीच अधिकतम संचारण दूरी 150 किमी है. |
| एस150 | 806~826 1427.9~1447.9 2401.5 – 2481.5 | |
| एमके50 | 1400~1529.9 | Mesh wireless network version. Mesh network mode. दो बिंदुओं के बीच अधिकतम संचारण दूरी 50 किमी है. |
| एम50 | 806~826 1427.9~1447.8 2401.5 – 2481.5 |
Only the same core modem can communicate with each other, different core modems can‘t communicate with each other.
3. 10-Watt RF power amplifier is available for 806~826MHz, 1427.9~1447.9 मेगाहर्ट्ज, 2401.5 – 2481.5मेगाहर्ट्ज, 1420~12470MHz, 1470~1530मेगाहर्ट्ज. इसलिए, we can have TX900-10W to work in 806~826MHz, 1427.9~1447.9 मेगाहर्ट्ज, 2401.5 – 2481.5मेगाहर्ट्ज, 1420~12480MHz, 1470~1530मेगाहर्ट्ज.
To note, For the 1420~1530MHz band, we need to separate it into two sub-bands (1420~1480MHz, 1470~1530मेगाहर्ट्ज) since the 10-Watt RF power amplifier can’t support the whole 1420~1530MHz band in the same hardware board.
4. 1.4/3/5/10/20MHz bandwidths configurable, the larger working bandwidth supports more transmitting bitrates in the same condition. For 150km video transmitting, we suggest using 20MHz bandwidth (at least 10MHz).
5. For TX900-10W(1420~1480MHz) or TX900-10W(1470~1530मेगाहर्ट्ज), when setting the working bandwidth is 20MHz, it has about 6 central working frequency points; when setting the working bandwidth as 10MHz, it has about 12 central working frequency point;
The central working frequency will hop when it detects frequency noise. If the current working frequency channel is clean, it will not hop. That means the frequency hopping is not as regular as x times/second.
6. There are two solutions for 150km+150km relay transmitting:
Solution A:
Solution B:
We suggest solution A since it supports more bitrates transmitting than solution B. It is more reliable on video transmission when the RF signal is weak (low SNR).
On Oct. 25वां, we tested solution B. During the testing; it had little RF noise on the seaside and we can see A Mobile communication base station tower just about 100m nearby.
Signal reporting on the seaside:
We can see the SNR is about 2~4 on the seaside.
Signal reporting on the mountainside:
We can see the SNR is about 4~7 on the mountainside. The different SNRs on the two sides also approved that it had little RF noise on the seaside.
तथापि, the video was transmitted very fluently with little RF noise.
Star Networking Vs Mesh Networking for Drone or Robot.
| STAR Network | MESH Network |
|---|---|
| Point to Point Connection between nodes | Multi-point to multi-point connection between nodes |
| Infrastructure based | In Ad hoc mode, devices are autonomous and free to move. In Infrastructure mode, the movement of nodes is restricted to the control center. |
| Central control point is present | Infrastructure-based will have a control center whereas Ad hoc-based does not have it. |
| Nodes communicate via the control center. | It is self-configuring. |
| The central control point is present | Multi hop communication |
| Devices or nodes can not move freely. | Infrastructure-based will have a control center whereas Ad hoc based does not. |
| Links between nodes and central control points can be configured. | In Ad hoc mode, devices are autonomous and free to move. In Infrastructure mode, the movement of nodes is restricted around the control center. |
| Nodes communicate via the control center. | Nodes relay traffic to other nodes on the path. |
Technical Specification for the Repeater from one client
- It is required to create an SBUS video/data/signal transmission system with a relay station installed on a helicopter and Ground Controller.
- We need the ability to switch frequencies in the range from 800 मेगाहर्ट्ज से 1.4 GHz for SBus data and video transmission (analog and digital with minimal delays).
- Sector antenna for adjusting the gain of the transmitted/received long-range signal. The ability to work with 5 receiving nodes. Support for Ethernet and UART connections between the repeater on the helicopter and Ground Control requires a real-time image for the operator. The ability to work with 5 receiving nodes. Support Ethernet and UART connection between helicopter repeater and GC requires a real-time image for the operator.
1. Is your system capable of using 3 नोड्स? We have to use 3rd node as the repeater in the center between the transmitter and receiver.
हाँ, यह समर्थन करता है.
2. यदि मैं दो ड्रोन का उपयोग करता हूँ, एक ट्रांसमीटर है, दूसरा पुनरावर्तक है, और वे एक रिसीवर द्वारा नियंत्रित होते हैं. क्या TX900 मिशन विमान और रिले ड्रोन के नियंत्रण का समर्थन करता है?
हाँ, ऐसा करने के लिए तीन समाधान हैं.
TX900 में तीन डेटा पोर्ट हैं. विभिन्न पारदर्शी सीरियल पोर्ट के माध्यम से अंतर करें, जैसे रिले विमान को नियंत्रित करने के लिए D2 और मिशन विमान को नियंत्रित करने के लिए D3. नुकसान यह है कि निर्देश अलग से भेजने के लिए TX900 रिसीवर को दो सीरियल पोर्ट से कनेक्ट करने की आवश्यकता होती है.
थोक में डेटा भेजने के लिए उसी पारदर्शी सीरियल पोर्ट का उपयोग करें, और फिर लेयर प्रोटोकॉल जोड़ें (जैसे हेडर जानकारी) डेटा में अंतर करने के लिए कि किस विमान को डेटा प्राप्त करना चाहिए और संसाधित करना चाहिए. नुकसान यह है कि डेटा भेजने और प्राप्त करने की प्रक्रिया जटिल है.
या दो रिसीवर का उपयोग करें: एक रिसीवर मिशन विमान के लिए है (ट्रांसमीटर), और दूसरा रिसीवर रिपीटर ड्रोन के लिए है. The connection and operation are easier.
3. Our company “Boat-Sharing” is engaged in the development of pleasure boats with remote control.
I ask you to give a commercial proposal for the development and sale of a remote control system with a relay system through a pilot-free aircraft at a distance of up to 200 किलोमीटर. इसके अलावा, the boat must be equipped with a video camera with a video transmission system to the base station.
Our TX900 supports 10-watt PA 150km. It also supports relay if you buy three units. (One as transmitter, one as receiver, another as the receiver)
4. Is it possible to quickly change the operating mode (during the flight) of the repeater between point to point?
क्षमा मांगना, it can not. You can change the role of the transceiver to the transmitter, RECEIVER, or repeater on the ground.
5. If we stay under 30Km LOS and 50Km with Repeater. Kindly share the transceiver datasheet so my team can better understand the Ports and interface available. We would also need RSSI and telemetry.
Is your quotation bundled with antennas?
हाँ, our TX900 supports 30km LOS and 50km with repeater. (max 150~200km)
TX900 supports to show you real-time RSSI and telemetry.
Our quotation includes the four antennas. (two short antennae for the plane in the air side, two long antennae for the ground receiver)

7. Do you have a wireless video transmitter, RECEIVER, अपराधी, or relay for the forest?
Have you already tested your radio system inside the forest? I’m asking this for you because if you’ve already tested this, your experience will help a lot in my research.
Our idea is to stay at a fixed point outside the forest with the transmitter and control the ground robot, fix the receiver on the ground robot, and send it to the forest. We have developed another device that we are going to place on top of the treetops with a drone, and in this device, we can place the signal repeater that you have said you have.
Could you send me the radius models that you have available for this purpose and the technical specifications for me to check, कृपया?
8. क्या मैं रिमोट कंट्रोल के माध्यम से 2x ड्रोन उड़ान नियंत्रण को नियंत्रित कर सकता हूं?? एक है मिशन प्लेन, और एक रिले यूएवी है
हाँ, most drone video data telemetry link has one TTL and one Sbus data port. यदि आप रिमोट कंट्रोल के माध्यम से 2x ड्रोन उड़ान नियंत्रण को नियंत्रित करना चाहते हैं, तो आपके रेडियो लिंक में दो एसबीस कनेक्टर हैं. Our model 1933 model supports 2xttl and 2xsbus connector.
9. Are your products tested and guaranteed to meet the advertised specifications?
हाँ, all our products are fully tested and verified before shipment to ensure they meet the advertised specifications and performance standards. Our company was founded in 2005 and has many years of experience in the research, development, and production of reliable wireless transmission equipment.
Each unit undergoes strict quality control and functional testing before delivery. इसके अलावा, our technical support team works closely with customers to help resolve any specific issues they may encounter during use, ensuring stable and dependable performance in real-world applications.
For the ground receiver, D1 is a TTL serial port: black is GND, yellow is RX, red is TX
D2 and D3 are Sbus in interfaces: black is GND, yellow is Sbus in, and red is floating.
- Ground Receiver ( default IP is 192.168.1.13, पहुंच नोड)
D1 is TTL, डी2, and D3 are Sbus in (black is GND, yellow is Sbus in, and red is floating); - Aircraft Repeater / रिले ( default IP is 192.168.1.11, केंद्रीय नोड, also called relay)
D1 is TTL, D3 is Sbus out (black is GND, yellow is Sbus out, red is floating), D2 is useless; - Unmanned Ship transmitter ( default IP is 192.168.1.12, पहुंच नोड)
D1 is TTL, D2 is Sbus out (black is GND, yellow is Sbus out, red is floating), D3 is useless;
bi-directional optical system for drone li fi, FHSS полудуплекс, коптер-ретранслятором, передача hdmi на 15 километров комплект оборудования, передача hdmi на 15 километров комплект оборудования, OFDM – XP 4000, видео модем для фпв 10 км цифра, передача видео с дрона плаз,
क्यू: We need 3 terminals 5W 80km for base station and airplane, एंटेना के साथ, Base station -> Repeater -> Airplane.
ए: Then you need to buy 3 units of the 5W 80km version.
The repeater node is recommended to use 10 वाट, it is the central node, and the key node, 10 watts to ensure the signal is stronger.
It is best to use 10W at the center node. The two front planes to the repeater plane are 80km away. They are all in the sky. The signal will be better. तथापि, the signal 80km from the repeater plane to the ground station will not be very good, and it is 2D3U. इसके अलावा, the data to be transmitted may be relatively large, so the repeater plane is equipped with 10W so that the SNR received by the ground station will be higher and can receive a larger code stream.
This is the 3rd networking type in the below picture.
Considering that the relay is very important in this solution, its data volume is very large and it is a key node for uploading and downloading. We also recommend that you use 5 nodes and two different frequencies, जैसा कि नीचे चित्र में दिखाया गया है.
