Passive IoT: a step closer to the vision of ubiquitous IoT
This report is available to those subscribed to the IoT & Enterprise module.
The vision of ubiquitous sensing for IoT is not unattainable, at least when it comes to lower data rate applications. This is what passive (or ambient) IoT promises to deliver thanks to its advantages in terms of form factor, energy efficiency and cost. Passive IoT refers to the soon-to-be-specified IoT technology, which comprises sensors that will be smaller and cheaper compared to previous generations of IoT(e.g. NB-IoT, LTE-M). They will also be greener, as they will typically be powered through energy harvesting. Early forms of passive IoT can already be found in commercial applications. This report explores the development and commercialisation activity of passive IoT and provides a glimpse into future applications.

Industry Checkpoint: IoT, Q3 2025
As the telecoms industry and wider digital ecosystem evolve at an unprecedented rate, regularly assessing major developments and their implications is more important than ever. GSMA Intelligence's new Industry Checkpoint series helps navigate how the market is changing, identify the trends that matter and understand the implications.
Connectivity trends in robotics: 5G and cellular IoT are only just emerging
From a telecoms perspective, robotics was recognised early on as a key future use case during the planning and rollout of 5G around seven years ago. With 5G-Advanced now commercially deployed in early-adopter countries, it is timely to evaluate 5G’s real-world impact on robotics. We also explore how complementary technologies such as edge computing, IoT and eSIM are shaping the connectivity landscape.
