True IoT — The Underappreciated Demand Driver 💡
Connected IoT devices are expected to approach 40 billion globally by 2030, up from roughly 21 billion in 2025. Most of that growth is in Wi-Fi and Bluetooth — indoor, static, low-mobility applications that don’t require macro wireless infrastructure. But a meaningful and growing subset requires terrestrial cellular connectivity: autonomous vehicles, mobile robotics, connected agricultural equipment, nomadic industrial sensors, emergency response systems, and any application where latency is critical and the device moves.
Satellite cannot serve these applications at scale. The latency constraints on autonomous vehicles are measured in milliseconds. Satellite, even LEO, cannot (yet) reliably deliver that, especially at the scale necessary. For latency-critical, mobile use cases, terrestrial macro wireless is not one option among several — it is the only option.
The connectivity stack that will emerge is layered: Wi-Fi and fiber for indoor static applications; terrestrial cellular for mobile and latency-critical uses; satellite for mid-latency, non-urgent applications in remote areas; and private 5G for large venues and enterprises. Macro towers are the backbone of the cellular layer. That layer is not going away.
