Caltta Powers Comms for 80th Victory Anniversary Military Parade

Beijing, China – October 2025 — Caltta Technologies, a leading provider of mission-critical communications solutions, successfully delivered end-to-end communication support for the 80th Anniversary Commemoration of Victory in the World Anti-Fascist War – highlighted by a grand military parade – held in Beijing on September 3, 2025.

The commemorative event, centered on a high-profile military parade showcasing national defense 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 on-site activities placed exceptional demands on network stability, real-time performance, and anti-interference capability. As the core communications support provider, Caltta ensured smooth and reliable operations throughout the event, demonstrating its technological strength and professional commitment.

Solid Technologies Powering a Complex Mission

The communication system for the event faced dual challenges — 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 ensured uninterrupted voice communications and the real-time relay of command instructions in a complex radio environment.

The narrowband trunking network also worked in tandem with 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.

The narrowband trunking network successfully supported more than 40 organizations and over 22,000 active users, covering 29 event procedures without a single communication interruption or failure.

Precision Execution Through Rigorous Preparation

Behind this flawless performance was meticulous planning and teamwork. During the preparatory phase, Caltta collaborated with relevant departments to establish a joint expert task force. The team conducted multiple rounds of on-site 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, ensuring “zero failure, zero interruption, and zero complaint.”
