20W Ethernet Data Link Transmitter , Wireless AV Transmitter and Receiver 921600bps

20W Ethernet Data Remote IP Transmitter for Vehicle / Vessel Mobile Transmission

Description:

DS-FDD20W is a high power Network IP radios based on COFDM modulation.It's special designed for Vehicle or Unmanned control vehicle in need for robust video wireless communcation and data control through IP network.

DS-FDD20W Long Range Video And Data Link Transmitter And Receiver 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. KP-FDD20W Long Range Video And Data Link Transmitter And Receiver supports bi-directional point to point, point to multi-point, multi-point to multi-point NLOS & LOS mobile wireless transmission.

DS-FDD20W 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. DS-FDD20W adopts the leading COFDM modulation, multiplexing & FDD technology (Frequency Division Duplex) 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 & RS232, RS422& RS485 data for audio video data transmission & reception.

With AES 128/ 256bit encryption & user defined passwords, the confidentiality is strengthened.  DS-FDD20W occupies relatively narrow band frequency(4/8 MHz) and has strong anti-multipath interference capacity. That overcomes the limitation of the analog technology & COFDM modulation in high-speed mobile or NLOS (Non Line of Sight) wireless transmission. Therefor, FDD 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.

COFDM advantages:

Strong anti-interference: FDD is effectively against the multipath interference of signal waveform with the COFDM modulation. When the frequency selective fading occurs due to multipath transmission in the channel, only the subcarriers in the band depression and the signal carried by them are affected. The other subcarriers are not affected. Therefore, the overall bit error rate of the system is lower.

Anti-multipath fading: The COFDM Transceiver is effectively against the interference with the multi-carrier technique (COFDM). Compared to the single carrier, multi-carrier inherently resistant to time delay and has strong multipath capability. With joint coding of subcarriers & frequency diversity of the channel, the system’s performance is improved. Therefore, COFDM wireless system is suitable for multi-path environment and fading channel high-speed audio video data transmission.
