1420Mhz -1530Mhz frekans aralığı drone video veri bağlantı modülü

1420Mhz -1530Mhz frekans aralığı drone video veri bağlantısı 110Mhz frekans aralığına sahiptir, so it supports frequeny hopping (Bu model, iki yönlü kablosuz veri bağlantısı ile video ve veri kablosuz iletimi için tasarlanmıştır.) en 11 ponits if set bandwidth 10Mb.

This is a special customized version of the Vcan1681 drone wireless video and data module.

	Sürüm 1	Sürüm 2
Frequency Range	806-826MHz 1428~1468Mhz 2401.5~2481.5Mhz	1420~1530Mhz
Frequency Hopping Range	Three frequency bands between 800Mhz, 1.4Ghz and 2.4Ghz.*	1420-1530MHz (now PA and antenna support)

* Frequency hopping at 800Mhz, 1.4Ghz and 2.4Ghz needs the power amplifier and antenna to support.

The1420-1530 MHz frekans aralığı for drone video data links is part of the L-bandı, known for its balance between range and data throughput, making it suitable for long-distance communication. Here’s a detailed breakdown:

Key Characteristics:

1. Frequency Range Attributes:
   • Longer Range: Lower frequencies (compared to 2.4 GHz/5.8 GHz) enable communication over greater distances, için idealGörsel Görüş Hattının Ötesinde (BVLO'lar) operasyonlar.
   • Better Obstacle Penetration: Effective in urban or vegetated environments where signals must pass through buildings or foliage.
2. Uygulamalar:
   • Commercial Drones: Used in infrastructure inspection, tarım, and delivery services requiring reliable long-range links.
   • Military/Government: Güvenli, robust communication for surveillance or reconnaissance.
   • Kamu Güvenliği: Emergency response drones in disaster zones where traditional networks fail.
3. Technical Trade-offs:
   • Lower Data Rates: Compared to higher bands, but modern compression (örneğin, H.265) allows HD video transmission.
   • Interference Mitigation: Techniques like frequency hopping or directional antennas may be employed to enhance reliability.
4. Zorluklar:
   • Mevzuata Uygunluk: Operators must ensure transmissions avoid protected frequencies (örneğin, 1400-1427 MHz). pratikte, systems often use 1427-1530 MHz to prevent overlap.
   • Spectrum Crowding: Increased use of L-band for aviation/satellite may require coordination.
5. Çözüm:
   • The1420-1530 MHz band is a strategic choice for drones needing uzun menzilli, 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.
