COFDM Relay Repeater

ड्रोन UAV वायरलेस व्हिडिओ ट्रान्समीटर आणि रिसीव्हर Vcan1870 साठी COFDM रिले रिपीटर मॉड्यूल

परिचय

The module is a relay module, not a completed item. Customers need to add a power amplifier, filters, and receiving and transmitting antennas for it to work effectively. These need to be customized according to the two working frequencies selected by the customer.

To prevent interference, the drone employs a single frequency (उदा. 400मेगाहर्ट्झ) for communication with the relay, and a different frequency (उदा. 700मेगाहर्ट्झ) for communication between the relay module with the receiver. The separation between the two should be as large as possible.

वैशिष्ट्य

1. Wireless Video COFDM Video Data demodulation and re-modulation
2. NLOS मध्ये स्थिर सिग्नल ट्रान्सफर आणि हाय-स्पीड मूव्हिंग (less than 600km/hour)
3. समायोज्य काम वारंवारता, बँडविड्थ, प्रसारण शक्ती, इ (Special Parameter Configure Tool or UART STM32 LoRA )
4. Lowest latency 200-300 मिलिसेकंद
5. Widely frequency range 200Mhz-3000Mhz
6. समर्थन व्हिडिओ स्वरूप
7. बँडविड्थ 1Mhz-8Mhz पर्यायी
8. Video signal repeater for long-distance

वारंवार विचारले जाणारे प्रश्न

1. What frequency does it support? Does it work well for my existing cofdm video transmitter and receiver?

1. Our COFDM Video Transceiver relay repeater supports 170-860Mhz. The COFDM transmitter also supports 2300Mhz, but the COFDM receiver only supports up to 860Mhz, 861-930Mhz receiver our COFDM-221 supports, over 930Mhz-2300Mhz needs to plus the frequency downconverter block to support.
2. Our COFDM relay repeater module supports all the COFDM transmitters and receivers, the transmission distance depends on your external power amplifier and filter support.

2. हे मॉड्यूल 1.4G वर सपोर्ट करते का?? उदाहरणार्थ 2.4G, 3जी, किंवा 3.6G?

1. होय, आधार.
