A Survey of IEEE 802.11 Protocols: Comparison and Prospective

Abstract

Abstract. Since the base version of IEEE 802.11 released in 1997, wireless local area network (WLAN) has been developing rapidly, and it has gone through many versions and amendments. The 802.11 protocol is now very sophisticated through 20 years of modification. Therefore, it is very hard to understand all improvements, which confuses researchers sometimes, making it not easy to discover the trend of development. This paper tries to summarize the key technologies that pushed WLAN forward among all important amendments, and then lists the latest research focus for the next generation of 802.11 family. The paper would provide assist researchers to find their field of interest.

Hardware Design of Single-Phase Smart Electricity Meter based on Multiple Wireless Connectivity Technologies

“…It increases the data rate up to 150 Mbps with the help of multiple antennas. The maximum outdoor coverage range is about 250 meters (Chen, 2017;Karmakar et al, 2017). The latest IEEE 802.11ax, also known as Wi-Fi 6, offers theoretical speeds of up to 10 Gbps.…”

Advanced IEEE 802.11ax TCP aware scheduling under unreliable channels

“…Most of the research papers on IEEE 802.11ax thus far examine new mechanisms in the PHY and MAC layers of the IEEE 802.11ax proposal . The issue of TCP traffic over IEEE 802.11ac networks has been investigated, eg, in previous studies, for unidirectional DL TCP traffic, unidirectional UL TCP traffic and both bi‐directional DL and UL TCP traffic.…”
