The main objective of this bachelor’s thesis was to verify the RF performance of MediaTek’s NB-IoT chipset according to 3GPP specifications. The objective was also to introduce LPWAN radio technologies and compare different technologies from the NB-IoT point of view. An overview of different IoT radios was made with a deeper approach to LPWAN radios. The NB-IoT radio technology was introduced more precisely than other ones because the main focus was on NB-IoT in this thesis. Maybe the most important factors for massive IoT communication devices are a long communication range, a long battery lifetime and a low cost and high network capacity. A comparison between different LPWAN radio technologies was made based on those factors. The NB-IoT proved to be considerable option according to these criterions set to the LPWAN radio technology. MediaTek believes that NB-IoT will be a key radio technology in the IoT industry. MediaTek’s first NB-IoT chipset meets the requirements of cost efficiency and small IoT devices and supports 3GPP Release 14 enhanced standards. The chipset RF verification is based on 3GPP standard requirements for the NB-IoT RF performance. 3GPP specification items for UE, both a transmitter and a receiver, are introduced in detail and RF measurement test limits are based on them. The RF automatic measurement environment is introduced and finally test result verdicts are listed according to specification items.
