System description:

TDD Individual Standard Definition Twoway voice Wireless Video Transmission system adopting
TDD twoway network transmission technology,on the basis of integration of the latest LTE
mobile TDS and terrestrial digital TV technology features and advantages,independent
research and development the design of new generation of Multiple access wireless
communication technologies,adopts the most advanced code modulation in multi-user wireless
communication field ,TDD-OFDM,LDPC error correction code,DPD,H.264 codec technology as the
core,assigning channel resources through slot control, through the sub-carrier frequency
flexibly assigned to multiple user terminals,within the same frequency maximized realized
access multiple endusers multiple access. In the NLOS and high speed movement realize
real-time two way transparent information transmission, Multiple wireless networks can be
integrated with each other layout large network coverage.

System function and characteristics:

1. with strong diffraction ability,Support two-way communication in a single frequency,
high frequency spectrum utilization;

Wide coverage, flexible allocation of channel resources, to achieve point to point, point
to multipointk multipoint to multipoint two-way communication.

Strong ability of error correction,adopts world most advanced LDPC error correcting code
technology,carrier to noise ratio threshold is 0.5dB under QPSK mode, approaching the
theoretical limit communication.

Anti-fading ability, the system has a strong anti-fading; TDD two-way image transmission
technology with respect to the single-carrier frequency domain equalization technology,
inherently long delay and strong anti-multipath capability, more suitable for urban
environments.

Video, audio, data and other multimedia information, high-speed, real-time, synchronous
transmission.

Good mobility, moving faster than 200km / h.

Using the latest pre-distortion technology, will reduce the PAPR, improve power amplifier
efficiency, TDD-OFDM mode allows the unit to open only in certain time slots, other times
you can turn off standby to save power.

Using the unique encryption technology, digital signal processing, strong system security,
stabilization and reliability.

Four network application architecture: a single center station, multi-center station, more
remote stations (multiple access) and personal piggyback onboard remote terminal of the
networking program.

Image quality: HD / SD / D1 / Half 720P optional.

11. GPS data interfaces: UART (compatible Beidou system).

System Application:

Can be used for public security, fire-fighting, traffic police, civil air defense
emergency, urban management and law enforcement, environmental monitoring, three anti-
emergency, flood control, emergency power, railway rescue, maritime law enforcement,
maritime surveillance patrol, customs border, port monitoring, forest fire prevention, oil
theft, more complex environment in real time transmission of high quality moving images for
the city, the sea, mountains and so on; military reconnaissance, television and so on.

System application form:
Overall transmission path is: Individual soldier - 5W portable base station,individual
soldier and mobile station is a two-way man moving body, it can be applied to any mobile
scene mode.

Typical applications for the general scene mode:Individual soldier - Communications command
vehicle, staff from the front carrying a transmitting device and then transmit the local
standard definition video signals to the communications command vehicle,communications
command vehicle can be directly monitor real-time monitoring by mobile base stations.In
addition, between the man and the command vehicle can real-time two-way voice intercom .

On the premise of staff at the front end of a two-way voice SD transmitter, a portable base
station supports up four-man back pass video and audio.

Communications command vehicle or command center can monitor through network at the same
time, access PC view video and recording operations .
