Abstract
This work is a data descriptor paper for measurements related to various operational aspects of LoRaWAN communication technology collected in Brno, Czech Republic. This paper also provides data characterizing the long-term behavior of the LoRaWAN channel collected during the two-month measurement campaign. It covers two measurement locations, one at the university premises, and the second situated near the city center. The dataset’s primary goal is to provide the researchers lacking LoRaWAN devices with an opportunity to compare and analyze the information obtained from 303 different outdoor test locations transmitting to up to 20 gateways operating in the 868 MHz band in a varying metropolitan landscape. To collect the data, we developed a prototype equipped with a Microchip RN2483 Low-Power Wide-Area Network (LPWAN) LoRaWAN technology transceiver module for the field measurements. As an example of data utilization, we showed the Signal-to-noise Ratio (SNR) and Received Signal Strength Indicator (RSSI) in relation to the closest gateway distance.
Highlights
Communication technologies for the IoT devices can be divided into three groups depending on the range: (i) short-range solutions that allow for connections at a distance below few tens of meters (e.g., Bluetooth Low Energy (BLE), ZigBee [12]); (ii) mediumrange, which can enable communication up to a few hundred meters (e.g., Wi-Fi solutions, DASH7, Ingenu); (iii) wide-range solutions, reaching few tens of kms in communication range (e.g., LoRaWAN, Narrowband IoT (NB-IoT), and Sigfox) [13,14,15,16,17]
Maximum transmission power limits are given by the LoRaWAN regional specification and by each country’s local regulations, which must be verified in advance
We provide the most important results obtained after postprocessing of the collected data
