Introduction

ST-3080TDA is SUNTOR special develop NLOS dual-way real time transmission system, adopted advanced TDD COFDM multiplexing technology, distribute the sources of information channel to users through time slot and frequency sub-carrier, to realize users joining up at single frequency. The information channel support AES128 and customer manual custom encryption key, assure the confidentiality of data, the system tie up relative narrow band and occupy air frequency (5/8MHz) with strong Multipath anti-interference, overcome analog and regular modulation technology that bring problem with transmission in high speed movement and barriers, make the transmission come true in complex environment such as: compressed data, audio, video, and other signals, Suitable for using in complex environment

Features

ST-3080TDA is special designed for high speed data transmission in movement. The transmit rate up to 2~8Mbps, which can meet high quality video, audio and data transmission. It includes text files, office documents, audio and video files, share files, access to the Internet, access the Intranet, access and download the database, dial telephone exchange, remote maintenance and other function on virtual network.

TDD Anti-electromagnetic Interference Performance

Compared with FDD need multi frequency to realize dual-way communication, TDD just requires only one single frequency, and these frequency also need big frequency space to avoid interference. Multi-carrier technology has strong ability to resist long delay and strong anti-multipath. So TDD is more suitable to apply in city environment

COFDM Anti-multipath Fading

It can be effective against signal interference between wave forms for high-speed data transmission and multi-path fading channel environment. When the channel appear frequency selective fading because of the multi-path transmission, only the sub-carrier band that falls depression and its carrying information will be affected. other sub-carriers are intact. Thus the overall system's error rate will be better.

Device Application Form

The device is suitable for data transmission in air. Wireless video transmission on UAV. Air to ground distance: 20-40km.
It also can be used for man-pack to communication van, communication van to communication van, communication van to monitor center, Ship to monitor center.
Horizontal Distance(on ground)(LOS): 10-15km
Horizontal Distance(on sea)(LOS): 15-35km

Application

Achieve PTP or PTMP two way data transmission; to meet the high quality video transmission, audio transmission, data transmission; including: text files, office files, audio and video files, shared files; access to the Internet, access to internal Network, access and download the database, dial switched telephone, remote maintenance, and so the virtual network can achieve the function.

The overall transmission path is: communication command vehicle ~ local command center ~ network to the provincial and municipal command center. Communication command vehicle and local command center to establish a wireless link, through the metropolitan area network or digital data communications.WAN transmission to the national provincial and municipal command center, to achieve two-way.
