Hong Kong's Office of the Communications Authority confirmed Thursday that the city has achieved 98.2 percent outdoor 5G coverage across all 18 districts, completing the principal buildout phase of the 5G Standalone deployment programme that began in 2022. Simultaneously, the authority announced the formal commencement of its 6G development programme, including initial spectrum planning, international standards engagement and a public-private research initiative targeting commercial 6G readiness by 2034.
The 5G Achievement
The 98.2 percent coverage figure, based on measurements conducted by the authority at 12,000 georeferenced test points across Hong Kong's territory including the outlying islands of Lantau, Lamma, Cheung Chau and Peng Chau, places Hong Kong among the world's top five jurisdictions by 5G coverage penetration. The four network operators, HKT, CSL Mobile, China Mobile Hong Kong, and SmarTone, have collectively invested approximately HK$14 billion in 5G infrastructure since the initial spectrum assignment in 2021.
The 5G Standalone architecture, now fully deployed, provides the complete set of 5G capabilities including ultra-low latency below 10 milliseconds, network slicing for dedicated virtual networks, and the edge computing infrastructure that enables time-sensitive applications to process data close to its source rather than in centralised data centres. These capabilities go substantially beyond the 5G Non-Standalone architecture initially deployed across Hong Kong, which provided higher speeds than 4G but lacked the advanced features of a complete standalone 5G network.

5G Applications Now Live
The completion of the 5G Standalone buildout has enabled a range of applications that required the full set of 5G capabilities. The Hospital Authority has deployed 5G-connected surgical robotics at three public hospitals, allowing specialists to perform procedures using robotically-assisted tools controlled from remote locations with latency low enough to maintain surgical precision. The MTR Corporation has implemented 5G network slicing to provide dedicated, guaranteed-bandwidth communications for its train control and operational systems, improving the reliability of its existing network while reducing dependency on legacy private networks.
Smart factory implementations, most notably at several manufacturing facilities in the New Territories, are using 5G to connect hundreds of sensors, automated guided vehicles and robotic assembly systems in real time, enabling production flexibility and quality control capabilities that were not achievable over wired networks or earlier generations of wireless technology.
The 6G Roadmap
The Office of the Communications Authority's 6G development programme is structured around four phases running from now to 2034. The current phase, running through 2027, focuses on research and standard-setting, with Hong Kong academics and industry researchers contributing to the International Telecommunication Union's IMT-2030 process that will define 6G technical requirements. A dedicated 6G Research Consortium, comprising HKUST, HKU, CUHK, PolyU and the four mobile operators, has been established with initial funding of HK$280 million from the Research Grants Council and the Innovation and Technology Fund.
Hong Kong's 6G Research Consortium has received HK$280M in initial funding and will contribute to the ITU's IMT-2030 6G standard-setting process.
Technical Aspirations for 6G
Industry researchers describe 6G not merely as a faster 5G, but as a qualitatively different communications paradigm. Target capabilities include peak data rates of 1 terabit per second, 1,000 times greater than 5G; end-to-end latency of less than 100 microseconds, enabling applications requiring virtually real-time feedback; integrated sensing and communication, allowing the network infrastructure itself to serve as a high-resolution environmental sensor; and AI-native network architecture where machine learning is embedded in every layer of the network rather than applied as an overlay.
The Secretary for Innovation, Technology and Industry noted that 6G will be the foundational communications infrastructure for the next generation of digital society, enabling technologies from holographic telepresence to fully autonomous transport systems that lie beyond the capabilities of 5G. "Hong Kong's early and active engagement in 6G research and standardisation ensures that we will be a shaper of this technology rather than simply a recipient of standards set by others," he said.
