HD SDI Full Duplex Wireless Video Transmitter and Receiver CE / FCC / ROHS
TDD-COFDM broadband wireless mobile emergency communication private network is independent of telecom operators.Its confidentiality,security,mobile performance that is better than the telecom operators,also is a fully transparent data encryption transmission emergency security network. Radio channel coding using TDD-COFDM modulation technology,has ability of two-way transmission support at the same exactly frequency and saving spectrum resources. Whatever,can enable real-time network IP transparent transmission and control and meet the two-way audio and video surveillance network.A base station can simultaneously achieve 255 mobile front-end management.Real-time monitoring from a central switching the monitor points equipments and corresponding base station working /standby state by a monitor central,which can be better for each mobile front-end monitoring.
Used in special government emergency use, such as: police, fire, maritime coastal defense, waterways, ports, digital urban management and other departments.
