ການນໍາສະເຫນີ

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 (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.

UART AT commands

The AT commands mainly used in the COFDM Wireless Relay Repeater are ATDR, ATSD, ATGD, ATSR, ATGR, and ATGB. For the introduction of specific commands, see the document.

FAQs

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

1. Yes, ສະຫນັບສະຫນູນ.
