Semiconductor Solutions for Smart Cities 

According to United Nations estimates, nearly 70 percent of the world’s population is expected to live in cities by 2050. Many municipalities are integrating low power wide area networks (LPWANs) to digitally transform its citywide infrastructures to make smarter decisions about services needed to effectively meet this urban influx. By deploying an Internet of Things (IoT) sensor network, cities can derive data-driven operational efficiencies that improve public services provided and enhance quality of life for citizens and visitors.

Sensors play a critical role for streamlined data collection and analysis that helps drive intelligent decisions about city services and resources, such as:

  • Energy consumption and sustainability
  • Parking management
  • Public transportation
  • Waste collection management
  • Water management and protection
  • Wireless gas monitoring

With its low power and long battery life, LoRa® is an ideal technology for smart city applications relying on battery-powered sensors needing up to 10 years of battery life. Using the unlicensed spectrum, devices featuring LoRa ICs connect seamlessly over public, private or hybrid LoRaWAN® networks, whether indoor or outdoor. Networks are complementary to Bluetooth, Wi-Fi and Cellular.

Semtech also offers electrostatic discharge (ESD) protection, surge protection and isolated power switches to help digitize IoT-connected smart city infrastructure.
