A white paper released today by the Wireless Broadband Alliance(WBA) and the LoRa Alliance titled Wi-Fi & LoRaWAN Deployment Synergies: Expanding Addressable Use Cases For The Internet of Things illustrates new business opportunities that are created when Wi-Fi networks are merged with LoRaWAN networks.
Massive IoT applications are less latency sensitive and have relatively low throughput requirements, but they require a huge volume of low-cost, low-energy consumption devices on a network with excellent coverage, which can be achieved with Wi-Fi networks.
The white paper addresses the growing popularity of IoT use cases in domains that rely on connectivity spanning large areas that are able to handle a huge number of connections, ultimately driving the demand for massive IoT technologies.
According to the paper, Wi-Fi connectivity covers short- and medium-range use cases at high data rates and may require more power, making it the preferable technology for people-centric mains-powered applications like real-time video and Internet browsing.
Meanwhile, LoRaWAN covers long-range use cases at low data rates, making it the preferable technology for low bandwidth applications, including in hard to reach locations, such as temperature sensors in a manufacturing setting or vibration sensors in concrete.
When utilized in conjunction with one another, Wi-Fi and LoRaWAN networks optimize a number of IoT use cases, including:
· Smart Building/Smart Hospitality:Both technologies have been deployed for decades throughout buildings, with Wi-Fi used for things like security cameras and high-speed Internet, and LoRaWAN used for smoke detection, asset and vehicle tracking, room usage and more. The paper identifies two scenarios for convergence of Wi-Fi and LoRaWAN, including accurate asset tracking and location services for indoor or near buildings, as well as on-demand streaming for devices with battery limitations.
· Residential Connectivity: Wi-Fi is used to connect billions of personal and professional devices in homes, while LoRaWAN is used for home security and access control, leak detection, and fuel tank monitoring, and many other applications. The paper recommends deployingLoRaWAN picocells that leverage Wi-Fi backhaul to the user set top box to expand coverage of home services to the neighborhood. These “neighborhood IoT networks” can support new geolocation services, while also serving as a communication backbone for demand-response services.
· Automotive & Smart Transportation: Currently, Wi-Fi is used for passenger entertainment and access control, while LoRaWAN is used for fleet tracking and vehicle maintenance. Hybrid use cases identified in the paper include location and video streaming.
The paper also outlines a number of deployment models and details frontend and backend integration and security processes.
