Huawei Fan Lifeng: NB-IoT opens the "golden age" for commercial scale
On August 16, 2017, during the China International Internet of Things and Smart China Summit organized by IOT, Fan Lifeng, Vice President of Huawei's Operator BG Marketing, delivered a keynote speech titled "The Golden Age for NB-IoT to Scale Commercialization." His presentation focused on the three major global trends shaping the Internet of Things (IoT), the worldwide rollout of the NB-IoT network, and the six key application scenarios for NB-IoT technology. This speech was warmly received by over 700 attendees.
In his address, Fan Lifeng highlighted several significant developments in the IoT sector. According to research by Vodafone Global, which surveyed 1,096 corporate executives across 17 countries, there are three critical trends: First, more businesses are adopting IoT services, with 60% either already utilizing or planning to deploy IoT solutions. These figures have nearly doubled annually over the past three years, starting from 12%, then 22%, and reaching 36%. Second, companies are increasingly allocating budgets for IoT initiatives, with 24% investing in areas like cloud computing, mobile communications, and big data. Third, a growing number of firms are seeing tangible returns on their IoT investments, with 63% reporting substantial gains. In fact, 24% of these businesses experienced a 10% boost in revenue thanks to IoT.
Looking at the progress of NB-IoT networks globally, Fan Lifeng mentioned that in 2017, over 40 NB-IoT networks were commercialized in 30 countries. By 2018, he predicted that the world would witness a single, unified NB-IoT network.
Turning our attention to China, the domestic NB-IoT network has seen remarkable advancements. All three major telecom operators—China Telecom, China Mobile, and China Unicom—cleared the path for large-scale IoT service expansion earlier this month when they secured licenses for IoT operations.
China Telecom has been particularly active, having constructed an NB-IoT network comprising 310,000 base stations. Field tests in seven provinces and 12 cities, including Jiangsu, Shanghai, Guangdong, Henan, Fujian, and Zhejiang, have successfully completed commercial or trial operations. Starting in July, several regions such as Sichuan, Beijing, Hunan, Hainan, and Gansu officially launched their next-generation IoT NB-IoT services.
Meanwhile, China Mobile announced its 2017-2018 Cellular IoT Engineering Wireless and Core Network Equipment Design and Feasibility Study Centralized Procurement Tender Notice on August 9, 2017, with an estimated project cost of up to 39.5 billion yuan. Additionally, China Mobile initiated a tender for the 2017-2018 Narrowband IoT (NB-IoT) Antenna Centralized Procurement Project, aiming to purchase approximately 1.11 million NB-IoT antennas. Chairman of China Mobile stated that by the end of 2017, the company plans to construct a mobile IoT (NB-IoT) network covering 346 cities, signaling its commitment to strengthening IoT infrastructure.
China Unicom also made strides in NB-IoT development. On May 15, 2017, Unicom announced the trial commercialization of its NB-IoT network in Shanghai, introducing applications such as smart parking, intelligent fire protection, and intelligent water services. Currently, Unicom has implemented NB-IoT pilots in over ten cities, including Shanghai, Beijing, Guangzhou, and Shenzhen. Notably, Shanghai Unicom, as the pilot site for the entire Unicom Group, built the world’s largest NB-IoT public network earlier this year.
These developments underscore the rapid evolution of IoT technologies and their increasing adoption across industries, highlighting the immense potential for future innovation and connectivity.
