University IoT Device Coexistence and Signal Quality Testing Report

This report focuses on the critical aspects of IoT device coexistence and signal quality, particularly in the context of low-power wide-area networks (LPWAN) like LoRaWAN. The report begins by emphasizing the importance of coexistence for reliable communication in crowded wireless environments, highlighting the challenges and the need for thorough testing. It then outlines a project involving field testing of LoRaWAN devices, detailing the different deployment situations for devices such as battery-operated temperature sensors. The testing plan includes gathering signal quality data (RSSI and SNR) under varying conditions, such as different distances from the gateway and inside/outside metal containers. The goal is to analyze the data and report on how deployment conditions affect signal quality, providing insights into optimizing IoT device performance. The report also references various research papers related to IoT, covering topics such as interoperability, security, and quality of service, providing a comprehensive overview of the subject.

Literature Review
Coexistence is very important for reliable and stable communication in the Internet of
Things. Without coexistence the dev ices of IoT cannot be counted on, to operate that is
intended in the wireless environments that are crowded. The device may not able to detect the
other devices of IOT or share the airwaves and can behave in dangerous or unexpected ways.
It is very challenging to make sure the coexistence of IoT devices. The most essential
action that can be taken is to perform the testing of coexistence. This helps to determine the
tolerance of the device to other radio signals and the characterizes its behaviour in the
presence of radio protocols.
Another range of technologies and the protocols that has appeared to fulfil the needs
of the IoT that is low-power wide area networks. The LPWAN is supposed to be to that IoT
what wifi is to the networking of the consumer. It offers coverage of radio over a wide area
by way of stations at the base and adapting the rates of power of transmission, modulation,
duty cycles and many more. LoRa is one of LPWAN protocol and it targets deployment
where the devices that are at the end do not need to transfer more than some bytes at a time.
The low power and long-range nature of LoRa makes it interesting for the technology of
sensing that are smart in the structure of civil as well as in the applications related to the
industries.
The wireless communications are assumed to be a common method that is used in the
market of IoT for connecting to the internet. There are several news about using 5G, LTE for
those communications of wireless devices and the IoT devices. By testing the quality of the
dev ices of IoT at the stage of development and by guaranteeing the quality, the problem of
after sales support can be minimized. The IoT equipments and the test solutions can check

and test the wireless communications quality at the development and manufacturing stages f
the devices of IoT.
