2. TDD COFDM Ethernet transceiver (SG-TDD1400) is our OEM military-level NLOS full duplex/ bi-directional audio video data transmission wireless mesh networking equipment. It is with transparent transfer protocol, strong anti-interference & strong diffraction. TDD COFDM transceiver supports bi-directional point to point, point to multi-point, multi-point to multi-point NLOS & LOS mobile wireless transmission.

4. TDD COFDM radio private network is independent of the telecommunication operators, which is confidential, secure & encrypted. It is special designed for emergency mobile wireless networking, communication & surveillance. The central monitor/mater transceiver real-time controls the related slave transceiver. TDD COFDM radio transceiver adopts the leading COFDM modulation , multiplexing &TDD technology (Time Division Duplexing) and distributes signal to the users via timeslot & the massive subcarriers of radio, which maximize the same frequency users. It is with RJ-45 Ethernet & RS-232, RS-422& RS-485 data for audio video data transmission & reception.

6. With AES 128/ 256bit encryption & user defined passwords, the confidentiality is strengthened. And TDD COFDM transceiver occupies relatively narrow band frequency(4/8 MHz) and has strong anti- multipath interference capacity. That overcomes the limitation of the analog technology & OFDM modulation in high-speed mobile or NLOS (Non Line of Sight) wireless transmission. Therefor, TDD COFDM Ethernet transceiver can transmit audio video data packet and other signals in complex environments, such as, under multi-path reflection, through buildings and others obstacles.
