Tiivistelmä
The advancement of technology has revolutionized the way we communicate and connect the world around us. One significant development in this regard is the emergence of wireless communication system, 5G, 6G and wireless local-area network (WLAN). Over the years, different versions of wireless fidelity (Wi-Fi) have been introduced, each offering fasters speeds and improved connectivity. The upcoming version of WiFi is WiFi7, also known as IEEE802.11be, which is the advancement in wireless technology aiming to revolutionize machine-to-machine communication.
IEEE802.11be or WiFi7 is an updated version of IEEE 802.11ax (Wi-Fi 6). It is expected to be a game-changer for Machine Type Communication (MTC), referring to the communication between machine type devices without human intervention, such as in Internet of Things (IoT) applications. With the increasing popularity and usage of IoT, MTC has become a crucial aspect of our everyday lives, from smart phones to industrial automations. IEEE802.11be plays a play a paramount role in MTC due to its enhanced features and capabilities.
In this thesis I have done some research of WiFi 7 with articles to explored key updates from WiFi 6, like 160MHz to 320Mhz, 16 spatial streams, 4k-QAM and OFDMA. And some features of WiFi 7, like HARQ, FD, NOMA, Multi-line operation. Also explained WiFi 7 use cases and limitations at the end. Simulation is included in this thesis with result figures which is done by Matlab. As a conclusion observed from the simulation results is depending on use cases we need to choose right MCS for different use cases. in some places were throughput matters, then use higher MCS. But in the place where speed is not important but need to be robust to attenuation then lower MCS can be also option.
In this thesis I will go through all the updated features and new features of about WiFi7, how does the features work and furthermore its use cases and challenges.
