Smart Grid, Smart Home, Smart City and Industry 4.0 need a lot of sensor data. However, the sensors, which collect this data, are often at locations, which are hard to reach with cables and cable installation is usually expensive. Connecting the Sensors with wireless technologies allows fast and easy use of the sensors. Therefore, the wireless transmission of sensor values provides enormous advantages. For wireless sensors the data rate is rarely important. More important are high energy efficiency, reliability, and coverage. A possible solution that provides these features is narrowband (NB) communication. Narrowband-technologies allow the efficient transmission of rare and small data packets (for example, the average temperature transmitted every hour). Such small packets are important for Machine-to-Machine (M2M) communication. This M2M communication is a necessary building block for new trends such as Smart Grid, Smart Home, Smart City and Industry 4.0. There are many technologies for narrowband communication, of which we will consider the most important ones in this document. LoRa, Sigfox and NB-IoT (Narrowband – Internet-of-Things) are the upcoming standards for the interconnection of many devices in the “Internet-of-things”. The use of these technologies will make mobile-sensor applications drastically simpler and, thus, allow visionary innovations. Examples for this are: intelligent parking management, automatic reading of water/power meter (smart meters), environment monitoring (for example, of rivers). However, many companies have no experience with wireless communication and cannot simply build systems based on narrowband communication. This document gives companies (mostly small and medium sized) companies an overview how to expand their existing systems and develop new applications based on narrowband technologies.PDF öffnen
