1420پیوند داده ویدیویی پهپاد با محدوده فرکانس -1530 مگاهرتز دارای محدوده فرکانس 110 مگاهرتز است., so it supports frequeny hopping (این مدل برای انتقال بی سیم ویدئو و داده با لینک داده بی سیم دو طرفه طراحی شده است) در 11 ponits if set bandwidth 10Mb.
This is a special customized version of the Vcan1681 drone wireless video and data module.
| نسخه 1 | نسخه 2 | |
|---|---|---|
| محدوده فرکانس | 806-826مگاهرتز 1428~1468Mhz 2401.5~2481.5Mhz | 1420~ 1530 مگاهرتز |
| Frequency Hopping Range | Three frequency bands between 800Mhz, 1.4Ghz and 2.4Ghz.* | 1420-1530مگاهرتز (now PA and antenna support) |
* Frequency hopping at 800Mhz, 1.4Ghz and 2.4Ghz needs the power amplifier and antenna to support.
این1420-1530 محدوده فرکانس مگاهرتز for drone video data links is part of theباند L, known for its balance between range and data throughput, making it suitable for long-distance communication. در اینجا یک تفکیک دقیق وجود دارد:
خصوصیات اصلی:
- Frequency Range Attributes:
- Longer Range: فرکانس های پایین تر (compared to 2.4 GHz/5.8 GHz) enable communication over greater distances, ایده آل برایفراتر از خط بصری (BVLOS) عمل.
- Better Obstacle Penetration: Effective in urban or vegetated environments where signals must pass through buildings or foliage.
- برنامه های کاربردی:
- Commercial Drones: Used in infrastructure inspection, کشاورزی, and delivery services requiring reliable long-range links.
- Military/Government: ایمن کردن, robust communication for surveillance or reconnaissance.
- امنیت عمومی: Emergency response drones in disaster zones where traditional networks fail.
- Technical Trade-offs:
- Lower Data Rates: Compared to higher bands, but modern compression (به عنوان مثال, H.265) allows HD video transmission.
- کاهش تداخل: Techniques like frequency hopping or directional antennas may be employed to enhance reliability.
- چالش:
- رعایت مقررات: Operators must ensure transmissions avoid protected frequencies (به عنوان مثال, 1400-1427 مگاهرتز). در عمل, systems often use1427-1530 مگاهرتز to prevent overlap.
- Spectrum Crowding: Increased use of L-band for aviation/satellite may require coordination.
- نتیجه:
- این1420-1530 مگاهرتز band is a strategic choice for drones needingدوربرد, reliable video links, especially in regulated or challenging environments. Compliance with radio astronomy protections (avoiding ≤1427 MHz) and proper licensing are essential for legal operation. This range is favored in sectors prioritizing reach and penetration over ultra-high data rates.
