• Teleoperation / Điều khiển từ xa: Not just video, but two-way data link supports remote flight control, parameter updates, telemetry feedback, vân vân.

• Mesh & Multi-Node Installations: For large areas or swarms of UAVs, ground robots or sensor networks, the mesh networking capability means nodes can relay through each other, extending coverage or providing redundancy.

• Disaster Response / Tìm kiếm & Giải thoát: The capability to transmit over 15-30 km (or further with PA), combined with audio communications, makes this module suitable for scenarios when teams are spread over large distances and need reliable live comms + băng hình.

Hiệu suất & Kỳ vọng phạm vi

• Without external power amplification, users can expect reliable LOS ranges up to 15-17 km (không đối đất). With suitable antennas, đường ngắm, and favorable conditions.

• Adding a power amplifier (2W, 5W, 10W) can extend range significantly, depending on antenna gain, terrain, and regulatory limits on radiated power.

• Signal quality, băng thông, and modulation adapt automatically to environmental conditions to maintain link performance; worse conditions reduce modulation order or bandwidth, but preserve the link rather than dropping.

Comparisons / Thuận lợi

What distinguishes the IS1681 from simpler, one-way video transmitters or basic RC control links:

• Bidirectional data & băng hình rather than just one-way video/telemetry.

• Support for full network topologies (mesh, relay networks) rather than simple point-to-point only.

• Multiple frequency options allow adaptation to regulatory and environmental constraints.

• Transparent IP networking means it can carry arbitrary IP traffic (ví dụ. băng hình, đo từ xa, điều khiển) rather than being limited to specialized proprietary protocols.

• Integrated serial/TTL interfaces make it easier to hook up flight controllers, máy ảnh, data loggers without needing many converters.

Considerations & Tips

• Regulatory compliance: When using higher transmit powers or certain frequency bands, ensure that operations are permitted in your area. Licensing, power limits, and band usage differ by country.

• Antenna setup: To get the advertised range, high-gain antennas, proper mounting (elevated, clear LOS), and matching connectors are essential. Diversity via the auxiliary antenna helps in multipath or blocked signal scenarios.

• Powering & heat dissipation: Even though module power consumption is modest (~4–5 W), including any PA will add heat. Good airflow / heatsinking is needed especially if enclosed. Use the onboard LED indicators to monitor link quality.

• Firmware & updates: Keep firmware updated for best performance and bug fixes. Use USB or Web UI as provided.

• Bandwidth allocation: If using mesh or multiple nodes, bandwidth is shared—so ensure the system design accounts for video + đo từ xa + control demands, and allocate uplink/downlink ratios as needed.

Câu hỏi thường gặp

Q: Can I purchase the modem core board separately?

If I can get the separate modem core board, I can introduce a wider range of customized products with different sizes and interfaces based on my clients’ requirements.

Does your company provide the core board shown in the image separately?

MỘT: Đúng, we can provide the modem core board separately for customers who have specific customization requirements. Tuy nhiên, based on our experience, using a standalone modem core board to develop a new customized product usually requires additional engineering work. The customer may need to redesign the motherboard (PCB), customize the mechanical structure, define new interfaces, modify the software/UI, and optimize the wireless RF parameters according to the final application requirements.

This type of customization normally requires cooperation between multiple engineering teams, bao gồm:

• Hardware engineers for PCB and interface redesign
• Software engineers for firmware, UI, and control software customization
• RF engineers for wireless frequency, quyền lực, and performance optimization

For a small quantity project, the development cost and engineering investment can be relatively high. Trong hầu hết các trường hợp, we recommend considering this approach when the expected production quantity is around 500 units or more. For lower quantities, using our existing complete wireless video transmission products with minor customization is usually a more cost-effective solution. If you have a specific project requiring a customized size, giao diện, frequency range, or application solution, please share your requirements. We can evaluate the feasibility and provide the most suitable solution.
