T331-10W vehicle-mount bidirectional transmission system is using the TDD-OFDM network transmission technology to achieve emergency communications command. Mainly for emergency situations, the command center leaders watch emergency scene audio and video, voice intercom with on-site communication car, enabling network data’s bidirectional transmission. So that the command center and communication car can be connected into the entire office network. The TDD-OFDM vehicle-video conferencing equipment uses,;; wireless channel using AES128 bit encryption; dual-mode positioning adaptive.
