Key Specifications
SG-FDD2W is a new generation digital 2 way duplex transceiver integrated with COFDM (Coded Orthogonal Frequency Division Multiplexing) modulation and FDD (Frequency-division duplexing) technology, and so have NLOS (non-line-of sight) diffraction and strong anti-interference ability. It has two different uplink & downlink carrier frequencies for signal transmitting and receiving, also compatible with super-linear digital predistortion, super narrowband (1MHz), low-latency and high-sensitivity capacity, that makes it ideal for long distance IP video data transmission.
As it’s lightweight and small size, It is mainly used for public security system, emergency, system, police, military etc secured video data transmission.
