Unidirectional HD видео връзка за 50 км латентност 50ms четири честота

Here is a demand.

We need a unidirectional video link for 50km. Video quality – HD, Video Latency 50 милисекунди, Ability to work on 4 independent non-standard channels (честота) for video transmission.

For a unidirectional video link over 50 км с HD качество, 50ms latency, и four independent non-standard channels, you will need a specialized long-range wireless transmission system. Here are some potential solutions:

1. Microwave or mmWave Links (Licensed or Unlicensed)

• плюсове: Can provide high throughput, ниска латентност, and long-range capability.
• минуси: Requires precise alignment and may need licensing.
• Example System: Ubiquiti AirFiber, Cambium Networks PTP 820

2. COFDM-based Wireless Video Transmitters

• плюсове: Designed for broadcast, robust against interference, and can work on custom frequencies.
• минуси: More expensive and may require custom tuning.
• Example System: Domo Tactical Communications (DTC), Vislink, Teradek Prism

3. Fiber Optic Link (If Feasible)

• плюсове: Zero latency, highest reliability.
• минуси: Expensive deployment over 50 км.

4. Custom SDR (Software-Defined Radio) Решение

• плюсове: Can be configured for non-standard frequencies.
• минуси: Requires significant R&д, spectrum analysis, and tuning.

Key Considerations:

• Frequencies: What range of non-standard frequencies are available?
• мощност: What are the power and interference constraints?
• LOS (Линия на зрение): 50 km needs a clear path or relay towers.
• Redundancy: Can you use multiple links for fail-over?

The recommended model is 1729, which meets almost all the needs of customers.

The customer’s requirement is to transmit 50 километри. Ако Vcan1729 is configured with a 5-watt amplifier, it supports a line-of-sight distance of 50 да се 80 километри. This requires a certain height difference between the transmitter and the receiver, such as from an aerial drone to a ground receiving station or from a mountain top to the surrounding area.

Customers require HD video quality. Our Vcan1729 with HDMI input supports 1080p HD video input encoding and transmission.

The customer requires a delay of 50 милисекунди. Нашите 1729 is an ultra-low delay solution, which can control the delay from transmitter to receiver to as low as 30 милисекунди. Its price will also be more expensive than the COFDM-908T with a delay of 150 да се 200 милисекунди. The specific choice depends on the customer’s needs and application scenarios.

Накрая, the customer mentioned that he needed 4 different frequencies to choose from. Нашите 1729 supports a 30MHz bandwidth frequency range, which means that if the operating frequency is centered at 595Mhz, its operating frequency range is 580Mhz~610Mhz. He can choose several other frequencies for transmission, such as 583Mhz, 589Mhz, 595Mhz, 601МЗХ, and 607Mhz. Of course, 595Mzh has the best transmission performance, because the power amplifier and antenna are customized within the range of +-15Mhz centered at 595Mhz.
