repeater model for one-way video data transmission unidirectional
For the one-way COFDM Video Data Transmission repeater, we recommended the model Vcan 1886, Which has built-in RX (receive) 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. To avoid interference, we also add the two filters, ca in poza de mai jos.
Repeater/Relay solution for two-way video data transmission bidirectional
Introducere TX900-10W PA și soluție ca repetor Drone
TX900-10W PA power amplifier supports drone repeater and FHSS function. Let me introduce the details below.
1. TX900 consists of a core modem (Vcan 1681, two-way wireless video, and data link module) și un de 2 wați, 5-watt, or 10-watt RF power amplifier inside. (un modem de bază și imaginea interioară PA de 2 wați)
2. Există două versiuni ale modemului de bază (același hardware cu firmware Soc diferit): The star wireless network version and the Mesh wireless network version.
| Numărul piesei | Banda de frecventa(MHz) | Tip de rețea |
| K150 | 1420~1530 | Star wireless network version.(P2P, P2MP) Poate fi folosit pentru transmiterea punct la punct, transmitere punct la mai multe puncte, și transmisie prin releu cu un singur nod. Distanța maximă de transmisie între două puncte este de 150 km. |
| S150 | 806~826 1427.9~1447,9 2401.5 – 2481.5 | |
| MK50 | 1400~1529,9 | Versiunea de rețea wireless Mesh. Mod rețea mesh. Distanța maximă de transmisie între două puncte este de 50 km. |
| M50 | 806~826 1427.9~1447,8 2401.5 – 2481.5 |
Doar același modem de bază poate comunica între ele, diferite modemuri de bază nu pot comunica între ele.
3. 10-Amplificatorul de putere RF Watt este disponibil pentru 806~826MHz, 1427.9~ 1447.9MHz, 2401.5 – 2481.5MHz, 1420~12470MHz, 1470~1530MHz. Asa de, putem avea TX900-10W pentru a funcționa în 806~826MHz, 1427.9~ 1447.9MHz, 2401.5 – 2481.5MHz, 1420~12480MHz, 1470~1530MHz.
A nota, Pentru banda 1420~1530MHz, trebuie să-l separăm în două sub-benzi (1420~1480MHz, 1470~1530MHz) deoarece amplificatorul de putere RF de 10 wați nu poate suporta întreaga bandă de 1420 ~ 1530MHz în aceeași placă hardware.
4. 1.4/3/5/10/20Lățimi de bandă în MHz configurabile, lățimea de bandă de lucru mai mare acceptă mai multe rate de transmisie în aceeași condiție. Pentru transmisie video de 150 km, vă sugerăm să utilizați o lățime de bandă de 20 MHz (cel puțin 10MHz).
5. Pentru TX900-10W(1420~1480MHz) sau TX900-10W(1470~1530MHz), când setați lățimea de bandă de lucru este de 20MHz, are aproximativ 6 punctele centrale de frecvență de lucru; când setați lățimea de bandă de lucru la 10MHz, are aproximativ 12 punctul central al frecvenței de lucru;
Frecvența centrală de lucru va sări când detectează zgomot de frecvență. Dacă canalul curent al frecvenței de lucru este curat, nu va sări. Asta înseamnă că saltul de frecvență nu este la fel de regulat ca de x ori/secundă.
6. Există două soluții pentru transmiterea releului 150km+150km:
Soluția A:
Soluția B:
Vă sugerăm soluția A, deoarece acceptă mai multe rate de transmisie decât soluția B. It is more reliable on video transmission when the RF signal is weak (SNR scăzut).
Pe Oct. 25th, am testat soluția B. În timpul testării, avea puțin zgomot RF pe malul mării și putem vedea un turn de stație de bază pentru comunicații mobile la aproximativ 100 m în apropiere.
Raportare semnal pe litoral:
Putem vedea că SNR este de aproximativ 2 ~ 4 pe litoral.
Signal reporting on the mountainside:
Putem vedea că SNR este de aproximativ 4 ~ 7 pe versantul muntelui. Diferitele SNR de pe cele două părți au aprobat, de asemenea, că avea puțin zgomot RF pe litoral.
in orice caz, the video was transmitted very fluently with little RF noise.
Star Networking vs Mesh Networking pentru dronă sau robot.
| Rețeaua STAR | Rețeaua MESH |
|---|---|
| Point to Point Connection between nodes | Multi-point to multi-point connection between nodes |
| Infrastructure based | In Ad hoc mode, dispozitivele sunt autonome și libere de mișcare. In Infrastructure mode, the movement of nodes is restricted around 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 where as Ad hoc based does not. |
| Links between nodes and central control points can be configured. | In Ad hoc mode, dispozitivele sunt autonome și libere de mișcare. In Infrastructure mode, the movement of nodes are 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 hexacopter and GC.
- We need the ability to switch frequencies in the range from 800 MHz to 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 hexacopter 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 noduri? We have to use 3rd node as the repeater in the center between the transmitter and receiver.
da, suportă.
2. Dacă folosesc două drone, unul este un transmițător, altul este un repetor, și sunt controlate de un singur receptor. TX900 acceptă controlul avionului misiunii și al dronei releu?
da, există trei soluții pentru a face asta.
TX900 are trei porturi de date. Distingeți prin diferite porturi seriale transparente, precum D2 pentru a controla aeronavele releu și D3 pentru a controla aeronavele de misiune. Dezavantajul este că receptorul TX900 trebuie conectat la două porturi seriale pentru a trimite instrucțiuni separat.
Utilizați același port serial transparent pentru a trimite date în vrac, și apoi adăugați protocoale de nivel (cum ar fi informațiile din antet) la date pentru a distinge ce aeronavă ar trebui să primească și să proceseze datele. Dezavantajul este că procesarea trimiterii și primirii datelor este complicată.
Sau folosiți două receptoare: Un receptor este pentru avionul de misiune (transmiţător), iar un alt receptor este pentru drona repetitoare. 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 kilometri. în plus, 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?
scuze, it can not. You can change the role of the transceiver to the transmitter, receptor, 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?
da, 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)
6. Bună, please check our request about the transmitter, receiver and repeater.
Bună, interested in radio communication (rx and tx)for UAVs at frequencies of 300-320MHz or non-standard frequencies that you can offer us, we also need matched antennas for them.
And the ability to connect to the Radiomaster tx16s remote via twisted pair or USB.
To spread the remote control and the transmitter at a distance.
The range of radio communication should be at least 10 km with a very noisy radio broadcast.

Or non-standard frequencies that you can offer us. The input voltage is from ~5 to 30 volți. As well as matched antennas to the kit.
Mulțumiri.
7. Do you have a wireless video transmitter, receptor, repetitor, 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, Vă rog?
