Abstract [en]

Dual-Band frequency theory consists of devices that operates on both high and low frequencies. Due to active development in our modern technologies in the fields of wireless communication networks, there is an increase in the demand for several devices that works on multi-frequencies. Wi-Fi compatibility in different devices is one of the examples in our daily life that works on dual-frequency. These devices include desktops, tablets, and smart phones that we use every day for different purposes like calling, texting, web browsing, video calling and so many other things. These all applications are possible due to the antennas that are installed inside these smartphones. These antennas are operating in both high frequencies and low frequencies to make a communication between the device and any Local Area Network (LAN). For such same purpose, VOI Technology is using Dual Band GNSS Module for their future IoTs termed as next-gen-IoT using the developed technology from Quectel. This GNSS module is designed in such a way that it can communicate with different satellite systems like GPS, GLONASS, Galileo, Beidou, and some other regional satellite technologies as well. It supports different band carriers like L1, L5, B1, and G1 to have constant communication with all satellite systems. This mode of communication increases the accuracy of the items on earth up to meters and in some cases up to centimeters. The Dual-Band GNSS module not only helps in identifying the position of the item but it also calculates other factors like speed of the GNSS module, longitude, latitude as well as altitude of the GNSS module. Tools used during the tests in different urban areas give information of all satellites in the range, signal strength, signal loss, and time information of signals. Dual-Band technology is one of the new technologies and with this project, documentation on the usage of this module will be available for VOI. It will work as a user manual guide for all engineers at VOI Technology to use in the future. Results analyzation of three different urban cities of Sweden will help in understanding the signal strength and signal loss at certain points. The exact location (longitude, latitude and altitude), speed of the GNSS module can be analyzed along with the starting time and ending time on the path of the test. Different number of satellites from different GNSS technologies will communicate with the module with the help of an active antenna, thus increasing the accuracy of the E-Scooters.
