TDD-COFDM is our new NLOS(non-line of sight) two-way data transmission system and wireless mobile emergency communication private network, which is independent of telecom operators wireless network. Its confidentiality, security, mobile performance that is better than Telecom operators. Also is a fully transparent data encryption transmission emergency security network.
Full Duplex Wireless Ethernet TDD-COFDM Video and data Transceiver
TDD-COFDM multiplexing technology to channel resources in time through time slot, frequency through a large number of sub carriers to flexibly allocated to multiple users, and in a single frequency to maximize the realization of multi user access. Channel into the AES128bit, and user manually customize key that strength to ensure the data encryption. System occupy relatively narrow-band air frequency(4/8MHz)and strong anti-multipath interference ability to overcome simulation technique and the high-speed mobile data transmission under multipath reflections and nuisance caused by occlusion, then achieved in a complex environment transfer: data packing form, audio and video data, serial asynchronous data, Miniature volume, precision design, lightweight and easy to carry that commonly used in short distance high speed wireless data transmission and on air long distance high speed wireless data transmission purposes.
