Next generation wireless-LAN: Security issues and performance analysis

摘要

Next generation wireless technology is breaking ground with the ability to pass the speeds of a gigabit Ethernet connections. With these technological advances it is important to also take into consideration the security of such technology. In this paper we focus on IEEE 802.11ac standard. We have recorded and analyzed 802.11ac wireless traffic with a packet capture software and compared the results with 2.4 GHZ 802.11n and 5.0 GHZ 802.11n traffic in terms of security improvements. The results of our analysis concluded that 802.11ac does not implement new features in the 802.11 architecture and has the same security weaknesses that exist in 802.11n and 802.11g. This paper also focuses on the performance of 802.11ac as compared to 802.11n 5GHZ and 802.11gn. The results concluded that 802.11ac significantly outperformed 802.11n 5 GHZ and 802.11gn.
