New focus on high-altitude platform internet

In the 1990s and 2000s, several projects were launched to explore the potential application of high-altitude platforms (HAPs) for telecommunication and remote sensing. The US, Japan and South Korea took the lead with several projects. HAPs are commonly deployed in the stratospheric layer, far higher than the altitude at which commercial aircraft operate, and are […]

Nanosensors and the “internet of nanothings”

With the internet of things (IoT) expected to comprise 30-billion connected devices by 2020, one of the most exciting areas of focus is on nanosensors capable of circulating in the human body or being embedded in construction materials. Once connected, this “internet of nanothings” (IoNT) could have a huge impact on the future of industrial […]
