The concept of the low-altitude economy has gained significant momentum in China over the past few years. It refers to economic activities that take place in airspace typically below 1,000 metres, including drones, urban air mobility, aerial logistics, surveillance, and emergency services. What was once largely experimental is now being scaled up through coordinated policy support, industrial participation, and increasingly sophisticated communications infrastructure. A key enabler of this transformation is the rapid evolution of China’s digital connectivity networks. Operators such as China Mobile are building integrated communication systems that combine terrestrial networks, satellite links, and specialised low-altitude connectivity capabilities. This integrated approach allows communication services to extend beyond traditional ground-based coverage and support applications across air, sea, and land. China Mobile has been expanding what it describes as an integrated air, space, gro...

China is increasingly asserting its presence in the low Earth orbit (LEO) satellite broadband arena, with two major constellation programmes, one state-backed and one commercially driven, now under active deployment. The government’s strategic plan for global communications infrastructure includes the Guowang network, targeting as many as 13,000 satellites, and the municipally supported Qianfan, also known as “Thousand Sails,” which aims for around 15,000 satellites. As of November 2025, Guowang has exceeded 100 satellites in orbit following a launch of nine satellites on 10 November. The Qianfan project, by contrast, has deployed around 90 satellites to date, a fraction of its target for regional coverage by the end of 2025. Both networks face significant challenges including manufacturing scale-up, launch cadence, orbital debris and regulatory timelines, yet their evolution has direct implications for the future architecture of global broadband, the integration of satellite and terre...

As mobile networks expand into new vertical domains, the low altitude economy (LAE) is emerging as one of the most promising frontiers for connectivity. In China and Hong Kong, this area is rapidly evolving with strong government support, early infrastructure deployments and growing commercial interest. It includes services and applications that operate in airspace typically below one thousand metres, covering everything from drone deliveries and infrastructure inspections to emergency response and environmental monitoring. The LAE is not just a collection of novel use cases. It represents a structural shift in how connectivity infrastructure is being designed and deployed. A layered approach is taking shape, combining reuse of existing terrestrial networks, new network deployments tailored for low altitude operation, and integration with non terrestrial networks such as satellites. Together, these networks are already delivering coverage up to 600 metres with end to end latency under...

Back in March this year, NTT Docomo announced that they are switching off their NB-IoT network due to not enough demand but will continue to support LTE-M and Cat 1 . Good spot. An odd reason to give "in order to concentrate management resources". You wouldn't think it would take much resource. — Tom Rebbeck (@tomrebbeck) March 30, 2020 This news have started a lot of discussions, as you would expect, about the future of NB-IoT. From the standards point of view, IoT is going ahead full steam with both LTE-M and NB-IoT having been enhanced for 5G in Release-16 to support massive Machine Type Communications (mMTC). This slide from Qualcomm illustrates it well A recent article from Mobile World Live had a heading, " China Mobile migrates IoT connections off 2G ". While reading the article, you would get a feeling that China Mobile will stop supporting the 2G IoT (more like M2M ) devices. But again this might not be that straightforward as I explain i...
