TDD-COFDM Audio/ Video/ Data Transmission System for large UAV
system
Introduction:
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.
High Quality:
- Modulation: TDD-COFDM channel modulation technology, with
ultra-wideband, full transparent transmission.
- Security: private network, private communication transport
protocol, the only synchronization code, AES encryption.
- Flexibility: transparent transmission of IP data channel, supports
multi-user access.
- Scalability: all-digital network, is compatible with all IP data
transmission equipment.
- Customized key password.
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.
