Large-scale events feature spacious venues, wide coverage and dense crowds. Traditional communication solutions suffer from signal blind spots, transmission lag and poor coordination, failing to support security dispatching, audio & video transmission and emergency response. Full-area video monitoring is also required to maintain on-site order and personnel safety.

We deploy a wireless ad hoc network integrating fixed nodes, mobile nodes and command center. Fixed nodes are installed at commanding heights to build the main network, eliminate signal blind spots and perform high-altitude video surveillance. Mobile terminals carried by security patrol vehicles and staff automatically access the network. On-site audio and video signals are transmitted to the command center in real time to support real-time situation monitoring, command issuance and emergency disposal. All teams collaborate closely to achieve full-coverage management and ensure on-site safety.
