Saisi x China Unicom | It's a new record! Saisi has won the bid for the 2025 China Unicom time synchronization equipment centralized procurement project.

Recently, Saisi Electronics, a leading clock synchronization company, has secured the top position in the telecom operator market. It won the 2025 centralized procurement project for time synchronization equipment from China Unicom with the highest overall ranking and the largest share.

1. Precise Timing and Location, Connecting the Future: Saisi Wins a Multi-Million Yuan Project from China Unicom

As an important part of China Unicom's new digital infrastructure construction, this centralized procurement project will purchase 189 sets of backbone network and local network time synchronization servers, with a total amount of tens of millions of yuan. It covers core machine rooms, aggregation machine rooms, and 5G base station access layers in 32 provincial-level administrative regions of China, providing precise time and frequency benchmarks for the construction of 5G-Advanced, industrial internet, and computing power networks.

This latest bid win marks Saisi's second major triumph in large-scale procurement projects for major telecom operators this year, following its successful bids for China Mobile's 5G synchronization network clock equipment worth over 200 million yuan and China Telecom/China Unicom's miniaturized clock synchronization devices. These consecutive achievements demonstrate the market's high recognition of Saisi's technical prowess and service capabilities.

2. Cutting-edge technology drives the development of 5G's "synchronous foundation"

As a first-tier supplier of China Unicom Group, Saisi once collaborated sincerely with China Unicom Group to build China's first integrated time-frequency (IEEE 1588) commercial synchronization network—the Inner Mongolia Unicom backbone network time synchronization system.

The ultra-high-precision clock synchronization equipment Saisi has won the bid, backed by authoritative certifications from the Ministry of Industry and Information Technology (MIIT) and Tel Labs. Featuring multiple groundbreaking innovations, it perfectly meets China Unicom's synchronization requirements for building next-generation digital infrastructure with ultra-wide bandwidth, ultra-high speed, and ultra-precision.

3. Deep-rooted and persistent efforts, forging an industry-leading position

Saisi is dedicated to addressing gaps and building strengths across the entire industrial chain, from time source to time synchronization, time usage, and time-frequency chips. Its full range of clock synchronization products has been widely adopted in critical national infrastructure sectors such as GNSS, 5G/6G communications, smart grids, industrial IoT, financial trading systems, smart cities, and aerospace, as well as in emerging future industries including the metaverse, VR/AR, artificial intelligence, blockchain, advanced manufacturing, and autonomous vehicles.

With its outstanding technical capabilities and product quality, Saisi has successfully served over 1,000 industry-leading clients both domestically and internationally. The company has constructed large-scale clock synchronization networks for more than 70% of China's provincial backbone networks and major power projects such as ultra-high voltage, creating a "new cloud universe" for leading Chinese cloud service providers like Alibaba Cloud and Tencent Cloud. It has also provided highly precise time synchronization solutions for hundreds of financial clients and developed multiple classic rail transit cases in over 10 countries and regions worldwide.

Upon completion, this awarded project will significantly enhance China Unicom's 5G/6G network synchronization capabilities, supporting nanosecond-level time synchronization requirements. It will not only deliver superior network experiences for consumers but also powerfully advance time-sensitive applications such as telemedicine, autonomous driving, and industrial internet.

To achieve greater precision in the future, Saisi will maintain its annual R&D investment at the billion-yuan level. Capitalizing on its 5G leadership, the company has established a dedicated 6G spatiotemporal synchronization technology research team, focusing on integrated space-ground coordination and cutting-edge technologies to advance 6G spatiotemporal synchronization. Guided by customer needs, Saisi will continuously enhance its core competitiveness and market influence, providing robust technical support for 5G/6G network development.

Saisi is eager to collaborate with industry partners to jointly pioneer a new chapter in 5G/6G communication development.
