SEB1&DR2C COFDM Two-way FDD Transceiver Module

    -- COFDM two-way FDD(Frequency Division Duplexing) wireless Transceiver
    -- Transmitting frequency band: 70MHz~4GHz, receiving frequency band: 160MHz~860MHz
    -- 1 Ethernet port and 1 data uart port
    -- Support bidirectional transparent data transmission via Ethernet/uart ports
    -- AES256 encryption / decryption
    -- Control uart for management
    -- Wireless transmission delay less than 30ms

SEB1&DR2C module is a bidirectional transmission wireless link, it is composed of two independent unidirectional wireless channels, and the wireless links in both directions operate in different frequency bands. The wireless link itself does not have a handshake protocol, so when one direction of the wireless link is interrupted by interference, it does not affect the data transmission of the other direction of the wireless link. The Ethernet port supports TCP/UDP/IP protocols.

Features:

• COFDM modulation and demodulation
• Stable signal transfer in NLOS and high speed moving;
• Adjustable working frequency, band width, transmission power, etc;
• Ethernet/uart connection for IP data/uart data broadcast transmission;
• Each direction maximum 31.67Mbps wireless transmitting bitrates;
• Wireless transmission delay less than 30ms;
• Great security by AES256 encryption.
