Mastering IOT

By: Colin Dow, Perry Lea

Overview of this book

The Internet of Things (IoT) is the fastest growing technology market. Industries are embracing IoT technologies to improve operational expenses, product life, and people's well-being. We’ll begin our journey with an introduction to Raspberry Pi and quickly jump right into Python programming. We’ll learn all concepts through multiple projects, and then reinforce our learnings by creating an IoT robot car. We’ll examine modern sensor systems and focus on what their power and functionality can bring to our system. We’ll also gain insight into cloud and fog architectures, including the OpenFog standards. The Learning Path will conclude by discussing three forms of prevalent attacks and ways to improve the security of our IoT infrastructure. By the end of this Learning Path, we will have traversed the entire spectrum of technologies needed to build a successful IoT system, and will have the confidence to build, secure, and monitor our IoT infrastructure. This Learning Path includes content from the following Packt products: Internet of Things Programming Projects by Colin Dow Internet of Things for Architects by Perry Lea

LoRa and LoRaWAN


LPWAN also include technologies that are proprietary and not sponsored by 3GPP. It can be argued that some IEEE802.11 protocols should also be classified in LPWAN, but the next two sections will highlight LoRa and Sigfox. LoRa is a physical layer for a long-range and low-power IoT protocol while LoRaWAN represents the MAC layer. 

Note

These proprietary LPWAN technologies and carriers have the advantage of using the unlicensed spectrum and that, simply, is data plan cost. Typically, technologies like Sigfox and LoRaWAN will be 5x to 10x lower in their data rates compared to traditional 3G or LTE connections for large volume deployments (>100,000 units). That may change with more competition from Cat-M1, Cat-NB, and Cat-5 but it is too early to tell.

The architecture was originally developed by Cycleo in France but then acquired by the Semtech Corporation (a French mixed-signal electronics manufacturer) in 2012 for $5 million in cash. The LoRa Alliance was formed in March...
