In urban environments, the combination of 5G and Wi-Fi 6/7 enables hyper-connectivity, facilitating smart traffic management, dense networks of public safety sensors (often using LoRaWAN or NB-IoT for cost-effective deployment), immersive urban experiences, and seamless connectivity for workers and residents.
Industrial Applications and Manufacturing
Industrial applications benefit tremendously from 5G and private networks, with factories leveraging private 5G for real-time control of autonomous guided vehicles (AGVs), wireless robotics, and augmented reality. LPWAN (LoRaWAN/NB-IoT) plays a key role here too, enabling wireless monitoring of environmental conditions, machinery health (vibration, temperature), tank levels, and energy sub-meters across vast factory floors or sprawling sites where wiring is impractical.
Smart Utilities and Infrastructure
This realm relies heavily on LPWAN technologies such as LoRaWAN and NB-IoT for automating meter readings (gas, water, electricity), monitoring bin fill levels, detecting water leaks across distribution networks, managing street lighting efficiently, and tracking air quality- all accomplished cost-effectively over wide areas.
Healthcare Innovation and Telemedicine
Healthcare innovation flourishes through 5G, BLE, and Wi-Fi. These enable remote patient monitoring via wearables, high-definition telemedicine, and tracking of medical equipment. LPWAN (e.g., LoRaWAN) extends this further by enabling low-cost, long-battery-life monitoring of ambient conditions in wards/storage (temperature, humidity), asset tracking of mobile equipment across large hospital campuses, and even patient wander management systems.
