Digital, intelligent empowerment: Innovation driving the future

China Telecom is building digital infrastructure for the AI era. It's developed four fully domestically produced, liquid-cooled intelligent computing clusters, each with 10,000 AI accelerator cards, across the Beijing-Tianjin-Hebei region, the Yangtze River Delta and the Guangdong-Hong Kong-Macao Greater Bay Area. It is also expanding its AI data center (AIDC) network. Moreover, the group's existing data centers have a combined capacity of nearly eight gigawatts, making it China's largest AIDC service provider.

The company's Xirang computing power platform connects and allocates resources across regions, service providers and architectures. It manages these resources centrally and supports efficient scheduling, with more than 119 EFLOPS of computing power available for allocation.

China Telecom has built the world's first and largest co-built and shared 5G standalone (SA) network. It pioneered the large-scale deployment of a new cloud-network integrated metropolitan area network and built the world's largest reconfigurable optical add-drop multiplexer (ROADM) network.

It is also developing an integrated satellite network spanning space, air and ground, combining narrowband and broadband connectivity and coordinating high and low-Earth-orbit satellites. The company was also the first in the world to enable direct satellite connectivity for mobile phones.

To serve its external customers, China Telecom has launched Xingchen TokenHub, a platform hosting more than 140 large language models. Its AI-native products include the proprietary Xingchen super agent TeleAgent and the AI Store portal.

The company has also introduced products such as Tianyi Smart Ringing, Smart Screen, Smart Viewing and Cloud Smart Phone, bringing new intelligent services to households. It is deepening the integration of government, business, home and consumer (GBHC) scenarios across production, daily life and social governance. This includes linking smart communities, digital villages and video networking to upgrade services and support digital transformation across industries.

Green, secure development: Building a sustainable foundation

China Telecom continues to improve its "1248" green development model. Over the year, it cut greenhouse gas emissions by more than 16 million metric tons, while emissions per unit of total telecommunications business volume fell 8.7 percent year-on-year.

It is developing greener cloud and network infrastructure, advancing green technologies and standards, and expanding energy-efficient products and applications. It's also encouraging the public to adopt greener lifestyles.

Under its dual approach of "Security for AI, AI for Security," China Telecom has built a dynamic protection system covering cloud networks, data, models and applications.

The company released the world's first distributed cryptographic system integrating quantum key distribution (QKD) and post-quantum cryptography (PQC). It also developed the first commercially viable integrated quantum and post-quantum cryptography device. China Telecom has provided communications support for disaster prevention, mitigation and relief efforts, as well as major events. 

Shared prosperity: Fulfilling corporate social responsibilities

Putting people first, China Telecom has built a comprehensive employee care system that supports both employee well-being and corporate growth. It also promotes open cooperation with partners across the industrial chain.

Moving forwards, China Telecom will keep national priorities at the forefront and make becoming a leading AI service provider central to its development in the intelligent era. Through its Cloudification, Digital Transformation and AI for Good strategy, it will further strengthen its service-oriented, technology-driven and security-focused capabilities.

Working with stakeholders, the company will uphold sustainable development, support the broader goals of the Communist Party of China and the country, promote high-quality economic and social development, improve people's livelihoods and fulfill its social responsibilities. Overall, it's aiming to write a new chapter in the development of the telecommunications sector as part of Chinese modernization.
