Model Number: SG-TDD20-S
Brand Name: SAFE GUARD
Key Specifications/Special Features:
Introduction: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 equipment 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.Specifications:Transmission mode: Full duplexTransfer Protocol: standard TCP/ IP, transparent transmission, serial asynchronousData type: 10/100Bate-T Ethernet, industrial RS-232, RS-422, RS-485 standardAudio channel: customized analog audio intercom interface (non-Open)Data Rate: 2Mbps ~ 8MbpsBaud rate: 720 ~ 921600bpsTransmission delay: 50~ 80msNetworking format: point-to-multipointBER: ≤10-6
