Clár ábhair

Réamhrá

The module is a relay module, not a completed item. Customers need to add a power amplifier, scagairí, 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 (e.g. 400Mhz) for communication with the relay, and a different frequency (e.g. 700Mhz) for communication between the relay module with the receiver. The separation between the two should be as large as possible.

Gné

Wireless Video COFDM Video Data demodulation and re-modulation
Stable signal transfer in NLOS and high-speed moving (less than 600km/hour)
Adjustable working frequency, bandaleithead, cumhacht tarchurtha, srl (Special Parameter Configure Tool or UART STM32 LoRA )
Lowest latency 200-300 milleasoicind
Widely frequency range 200Mhz-3000Mhz
Tacaíocht Mbps go 31.67Mbps
Bandaleithid 1Mhz-8Mhz roghnach
Video signal repeater for long-distance

Réamhrá

COFDM wireless video repeater relay module accepts COFDM signals from two antennas (or one) and demodulates them before re-modulating and transmitting via one antenna.

This relay module can quickly find and lock to an incoming transmission based on the pre-set frequency and bandwidth.

CCanna

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

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.
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. Does this module support over 1.4G? for example 2.4G, 3G, or 3.6G？

Is ea, tacaíocht.
