Mesh TDD Transceiver 1-200km COFDM Bidirectional Portable Radio Downlink Uplink


  1. Robust COFDM IP Mesh, the COFDM network transceiver, which is combined with mobile Mesh and COFDM IP communication unit, directly delivers HD video, data and VoIP without any ectra infrasture. Robust COFDM IP Mesh allows up to 16 portable mesh nodes to be rapidly connected into a self-forming, self-healing mesh network.
  2. COFDM wireless IP Mesh supports non-line-of-sight operation due to the use of coded orthogonal frequency division multiplexing (COFDM), making the system truly dynamic and mobile, ensuring secure and robust communications in the most challenging and rapidly changing environments.
  3. COFDM multi-hop Mesh (model KP-MESH340) is with COFDM modulation and AES 128 bit encryption, and frequency-hopping spread spectrum, so it has a wide coverage,strong diffraction ability, high transfer rate and self-encryption.
  4. COFDM multi-hop mesh, with up to 16 nodes for every mesh, performs well in point to point or point to multi-point (one to or one to many) communication, centerless ad hoc network and multi-hop communication.
  5. Small and light, COFDM multi-hop mesh is suitable for Aerial Surveillance, Marine Surveillance, Mobile Monitoring Station, Central Monitoring Station, Portacam on Tripod/ Patrol Car, SpyVest, Robot...Typical fixed deployments include first responder, rapidly deployable wireless networks, surveillance applications and long range wireless IP networks. Mobile applications include vehicle mounted convoy applications, body worn, mobile and advanced ground robot control,UAV to ground control station.

COFDM Technique Advantages:

  1. Strong interference:COFDM wireless transmitter 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.
  2. Anti-multipath fading: COFDM wireless audio video transmitter 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.
  3. LOS & NLOS operation: with strong penetration, strong diffraction & strong anti-interference, COFDM wireless system is suitable for high-speed mobile wireless transmission in NLOS &LOS operation without servo stability control assistance, such as on UAV to mobile vehicle, uav to groun station, UAV to vessle...
