Caltta powers comms for military parade

Caltta Technologies, a provider of mission-critical communications solutions, has successfully delivered end-to-end communication support for China’s 80th Anniversary of Victory in the World Anti-Fascist War — highlighted by a grand military parade held in Beijing on 3 September.

The commemorative event, designed to showcase national defence strength and historical remembrance, gathered over 50,000 participants on site and attracted hundreds of millions of online viewers. The massive scale and high density of onsite activities placed exceptional demands on network stability, real-time performance, and anti-interference capability. As the core communications support provider, Caltta was tasked with ensuring smooth and reliable operations throughout the event.

The communication system for the event faced the dual challenges of managing sudden high-density traffic while maintaining zero interruption for command communications. Caltta deployed its narrowband digital trunking system, delivering full-area coverage and stable service across Tiananmen Square and surrounding areas.

Leveraging software-defined radio (SDR) technology, the narrowband trunking system provided extensive coverage, strong anti-interference capability and high adaptability. Through dynamic software configuration of frequencies and signal parameters, the system enabled uninterrupted voice communications and the real-time relay of command instructions in a complex radio environment.

The narrowband trunking network worked in tandem with the Beijing Wireless Government Broadband Private Network to form an integrated ‘voice + video’ communication network, effectively meeting the intricate requirements of this large-scale national commemoration. It successfully supported more than 40 organisations and over 22,000 active users, covering 29 event procedures without a single communication interruption or failure.

Meticulous planning and teamwork went into ensuring the success of the event. During the preparatory phase, Caltta collaborated with relevant departments to establish a joint expert task force. The team conducted multiple rounds of onsite inspections and simulations to refine the technical plan, followed by three comprehensive drills to validate equipment performance and emergency procedures.

On the day of the event, Caltta’s technical experts operated on 24-hour standby, monitoring network performance in real time. Every operational detail — from equipment status to signal quality assurance — was managed by assigned personnel, with the aim of ensuring zero failure, zero interruption and zero complaint.
