1420МГц -1530 МГц частотны дыяпазон беспілотных відэаматэрыялаў модуля дадзеных

1420Дыяпазон частот МГц -1530 МГц Канал перадачы відэа з беспілотніка мае дыяпазон частот 110 МГц, so it supports frequeny hopping (Гэтая мадэль была распрацавана для бесправадной перадачы відэа і даных з двухбаковым бесправадным каналам перадачы дадзеных) у 11 ponits if set bandwidth 10Mb.

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

	версія 1	версія 2
дыяпазон частот	806-826Mhz 1428~1468Mhz 2401.5~2481.5Mhz	1420~ 1530 МГц
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 Дыяпазон частот МГц for drone video data links is part of theL-дыяпазон, known for its balance between range and data throughput, making it suitable for long-distance communication. Вось падрабязная паломка:

Асноўныя характарыстыкі:

1. Frequency Range Attributes:
   • Longer Range: Больш нізкія частоты (compared to 2.4 GHz/5.8 GHz) enable communication over greater distances, ідэальна дляЗа межамі прамой бачнасці (БВЛОС) аперацыі.
   • Better Obstacle Penetration: Effective in urban or vegetated environments where signals must pass through buildings or foliage.
2. прыкладанняў:
   • Commercial Drones: Used in infrastructure inspection, сельская гаспадарка, and delivery services requiring reliable long-range links.
   • Military/Government: Надзейны, robust communication for surveillance or reconnaissance.
   • Грамадская бяспека: Emergency response drones in disaster zones where traditional networks fail.
3. Technical Trade-offs:
   • Lower Data Rates: Compared to higher bands, but modern compression (напр., H.265) allows HD video transmission.
   • Interference Mitigation: Techniques like frequency hopping or directional antennas may be employed to enhance reliability.
4. Праблемы:
   • Адпаведнасць нарматыўным нормам: Operators must ensure transmissions avoid protected frequencies (напр., 1400-1427 МГц). На практыцы, systems often use1427-1530 МГц to prevent overlap.
   • Spectrum Crowding: Increased use of L-band for aviation/satellite may require coordination.
5. Заключэнне:
   • The1420-1530 МГц band is a strategic choice for drones needingдальнабойныя, надзейныя спасылкі на відэа, 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.
