Low Power, Wide Area Networks (LPWANs) are key to the success of Internet of Things (IoT) deployments that need to cover a broad geographical area. LoRaWAN® is an open protocol for one type of LPWAN, while DASH7 is another. Both use the unlicensed spectrum and together they offer complementary benefits.
On-boarding Devices Securely
There are many diverse applications for LoRaWAN® devices. Similarly, there is a wide and diverse population of end users. These factors lead to a device on-boarding process that takes just as many forms. Device on-boarding is the process of associating a device with a particular network and application server. It is the foundation of a device's level of security. It precedes and enables device activation, whether over-the-air activation (OTAA) or through activation by personalization (ABP), which themselves become compromised if the device on-boarding is done incorrectly.
Chirps are great for low power wide area networks (LPWAN) because they occupy a single dimension.
Let’s start with a real-world analogy: it is difficult to get lost in a one-dimensional space. For instance, if you walk along a coastline or a river it is fairly easy to find your way back. Similarly, it is possible to set up an appointment with a friend in a one-dimensional space (in a loose manner) such as “Let’s meet on Main Street near the restaurants.” If you’re both walking along Main Street near the restaurants at roughly same time, you will
With the continued maturation of low power wide area networks (LPWANs) and the Internet of Things (IoT), here are my predictions for the coming year:
