Model: SG-TDD20
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.
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.
