The Child Prodigies of IEEE 802.11 Family

WiFi was designed just to replace the wired connections, but it has changed the Internet as a whole. WiFi users are increasing day by day and the traffic from wireless devices is dominating the Internet. With an increasing number of users and their expectations on QoS(Quality of Service) and data rates, there is a need for better WiFi techniques which can support the above-mentioned challenges. The IEEE LAN/MAN standards committee (LMSC) has launched new protocols like IEEE 802.11ac, 802.11ad, and 802.11ax. Understanding them is very important to use them efficiently and effectively to fulfill our expectations. In this paper, we summarize few of the works which talk about the above the mentioned protocol standards of WiFi that brought a significant improvement in WiFi's performance. Moreover we discuss the differences in the protocols and their applications. We also try to compare these three protocols with respect to their supported data rates, range of transmission and Robustness.

How You See Me

Convolution Neural Networks is one of the most powerful tools in the present era of science. There has been a lot of research done to improve their performance and robustness while their internal working was left unexplored to much extent. They are often defined as black boxes that can map non-linear data very effectively. This paper tries to show how CNN has learned to look at an image. The proposed algorithm exploits the basic math of CNN to backtrack the important pixels it is considering to predict. This is a simple algorithm which does not involve any training of its own over a pre-trained CNN which can classify.
