| आवृत्ति सीमा | 806-826मेगाहर्टज 1428~1468Mhz 2401.5~2481.5Mhz | 1420~1530Mhz |
| Frequency Hopping Range | Three frequency bands between 800Mhz, 1.4Ghz and 2.4Ghz.* | 1420-1530मेगाहर्टज (now PA and antenna support) |
* Frequency hopping at 800Mhz, 1.4Ghz and 2.4Ghz needs the power amplifier and antenna to support.
NS1420-1530 मेगाहर्ट्ज आवृत्ति रेंज for drone video data links is part of theएल बैंड, known for its balance between range and data throughput, making it suitable for long-distance communication. Here’s a detailed breakdown:
प्रमुख विशेषताएँ:
- Frequency Range Attributes:
- Longer Range: कम आवृत्तियाँ (compared to 2.4 GHz/5.8 GHz) enable communication over greater distances, के लिए आदर्शदृष्टि की दृश्य रेखा से परे (बीवीएलओएस) परिचालन.
- Better Obstacle Penetration: Effective in urban or vegetated environments where signals must pass through buildings or foliage.
- अनुप्रयोगों:
- Commercial Drones: Used in infrastructure inspection, कृषि, and delivery services requiring reliable long-range links.
- Military/Government: सुरक्षित, robust communication for surveillance or reconnaissance.
- सार्वजनिक सुरक्षा: Emergency response drones in disaster zones where traditional networks fail.
- Technical Trade-offs:
- Lower Data Rates: Compared to higher bands, but modern compression (जैसे, H.265) allows HD video transmission.
- हस्तक्षेप शमन: Techniques like frequency hopping or directional antennas may be employed to enhance reliability.
- चुनौतियां:
- विनियामक अनुपालन: Operators must ensure transmissions avoid protected frequencies (जैसे, 1400-1427 मेगाहर्ट्ज). व्यवहार में, systems often use1427-1530 मेगाहर्ट्ज to prevent overlap.
- Spectrum Crowding: Increased use of L-band for aviation/satellite may require coordination.
- निष्कर्ष:
- NS1420-1530 मेगाहर्ट्ज band is a strategic choice for drones needingलंबी दूरी, 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.
