IoT Networks with LoRaWAN

About the Book

This book is about the LoRa modulation developed by the company Semtech which allows very energy efficient wireless communication over distances up to 12km. It also is about the LoRaWAN network technology which is based on the LoRa modulation and developed and maintained by the LoRaWAN Alliance.

This book addresses both prfofessional users and ethusiasts who just want to use LoRaWAN as a Hobbby or just for fun. It gives detailed background information how this technology works and what the strong point and limitations are. In addition to the theory is is shown how LoRaWAN can be used with a lot of code exampls for Arduino and various ARM platform like ARM mbed.
