Distributed Antenna Systems, commonly known as DAS, play a crucial role in extending mobile connectivity into environments where outdoor signals struggle to reach. From convention centres to hospitals, and from tunnels to stadiums, DAS ensures that users stay connected in areas where mobile coverage would otherwise be poor or non-existent. The main challenge arises from the fact that large buildings often block or degrade cellular signals due to their construction materials. DAS addresses this by redistributing the signal inside the structure through a network of antennas connected to a common source. This significantly improves coverage, capacity and user experience. To explore how DAS works in practice and the differences between types of solutions, we are sharing two insightful videos that break down the fundamentals and practicalities of deploying DAS. The first video, by WilsonPro, offers a straightforward explanation of passive and active DAS. Passive DAS, also referred to as sig...
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...
