What is LoRaWAN?
LoRaWAN is a specification for a telecom network and is suitable for long distance communication with low power. It is perfect for exchanging data between different objects, such as parking meters, cars, bus shelters and much more.
With the help of LoRa, all kinds of things can communicate with the internet without having to use 3G or Wi-Fi. The battery consumption is low, the range is long and the bandwidth is limited. In other words, perfect for the IoT (Internet of Things). It is possible to communicate with wireless sensors over this network. In this way, many new applications are possible. For example, locating your bicycle, pet or handbag. This also makes it possible to open and close gates, fences or other things remotely.
LoRa stands for long range and is a specification for a WAN (Wide Area Network). The equipment occasionally transfers some data and therefore does not require a constant internet connection. The connection has a range of 2.5 to 15 km per mast. The speed of the connection is between 0.3 and 50 kbits/s. In addition, the battery also lasts a very long time.
How does the LoRA communication work?
The LoRa technology consists of gateways, network servers and application servers. Radio frequency chips transmit a spread spectrum. A spread spectrum is a form of wireless communication in which the energy of the signal is deliberately spread over a specific frequency domain. These signals have a much larger bandwidth than the information they contain. As a result, the signal is noisy and difficult to detect or intercept.
