3. It greatly improves the ability of anti-multipath and anti-interference and has the characteristics of high reliability, good stability, and low delay.
4. This product is suitable for long-range drone, пожаротушение, инспекция, мониторинг, и другие сценарии, a transmission distance of 60KM+ when the environment is good.
5. The two data ports can be made as ТТЛ, RS232, UART, SBUS, RS485, or CAN.

Особенность

• It supports automatic power control: Close-range automatic transmission power change reduces power consumption.
• Supports automatic antenna selection: According to the occlusion situation, the optimal antenna transmission is selected in real-time.
• Supports upstream and downstream dynamic allocation: The bandwidth ratio of the master and slave can be automatically allocated according to the actual amount of data.

Передача на большие расстояния

The VCAN1933 supports long-range transmission with a 4Mbps code stream. Under line-of-sight conditions, it can transmit over 30 km up to 200km using a directional antenna. This long-range capability requires support from a power amplifier.

Large Bandwidth Transmission

The VCAN1933 has a maximum bandwidth of 17Mbps when using a 10MHz channel. This high throughput allows for efficient data transfer over long distances.

Customizable Working Frequencies

The default working frequency range for the VCAN1933 is 1350-1470MHz. Однако, the device can be customized to operate on other frequencies upon request. Some of the custom frequencies already made for clients include:

• 2.1~2.3GHz (2100~2300MHz)
• 1.7~1.9GHz (1700~1900MHz)
• 5.7ГГц (5700МГц)
• Dual frequency (600MHz downlink + 1400MHz uplink)

Multi-Interface Design

The VCAN1933 features a versatile interface design, в том числе:

• 2 RJ45 Ethernet for IP camera gimbal or connecting to the computer.
• 3 serial Data ports: RS232, RS422, and TTL

This allows for flexible connectivity options when deploying the micro base station.

Автоматический выбор частоты (Эта модель была разработана для беспроводной передачи видео и данных с двусторонней беспроводной связью.)

The VCAN1933 employs an automatic frequency hopping spread spectrum (Эта модель была разработана для беспроводной передачи видео и данных с двусторонней беспроводной связью.) technique. It automatically detects interference signals and selects the optimal frequency point in real time. This helps maintain reliable communication links.

Automatic Retransmission

The micro base station supports automatic retransmission of burst error data. This improves overall data reliability by ensuring that corrupted packets are present.

Адаптивная модуляция

The VCAN1933 automatically adjusts the channel modulation mode based on real-time signal quality. This adaptive modulation allows for optimal performance under varying conditions.

Автоматический контроль мощности

The VCAN1933 features automatic transmission power control. It can automatically reduce the power at close range to conserve energy. This helps extend the operational life of the system.

Automatic Antenna Selection

The VCAN1933 selects the optimal antenna for transmission based on real-time occlusion conditions. This ensures that the best antenna is used to maintain the link quality.

Dynamic Bandwidth Allocation

The VCAN1933 supports dynamic allocation of bandwidth between the master and slave units. The ratio can be automatically adjusted based on the actual data requirements, ensuring efficient utilization of the available bandwidth.

Вопросы-Ответы

вопрос: Is this an ad hoc mesh module (where all modules can communicate directly with each other)?
А: Нет, this is not a mesh system. It uses a star topology, where all modules connect to a central node. Communication between modules must go through this central node, rather than occurring directly between individual modules.

вопрос: We need a 50km distance MiMo FHSS capable of working at 0.8 Mach speed, do you have such modems?
А: Our model supports to selection of the frequency automatically, and it cannot convey such a fast speed at 0.8 Mach. It should be below 0.7 Mach, which is estimated to be 200m/s.

вопрос: Can you give me the answer to the below question list?

The standard configuration includes four omnidirectional fiberglass antennas. For enhanced signal strength, you might upgrade to directional flat panel antennas or Yagi antennas at the ground receiver side. Однако, keep in mind that these options require regular adjustments to ensure the antenna is always aimed at the drone. To simplify this process, you can use an automatic antenna gimbal, which will continuously orient the antenna toward the drone’s location. VCAN1916

вопрос: Can I control the 2x drone flight control via the remote control? One is mission plane, and one is relay UAV.

А: да. Most drone video data telemetry link has one TTL and one Sbus data port. If you want to control the 2x drone flight control via the remote control, then your radio link has two sbus connector. Our this model 1933 supports 2xttl and 2xsbus connector. Please tell us if you have this demand.
