Question 1: Wireless Networks Performance (Total: 20 Marks) a) A WLAN network administrator wants to efficiently enforce QoS in his network (such as reserve some channel for voice traffic, etc). Using WLAN information gathering tool 'Kismet' the network administrator captured the information regarding one of his AP as shown in Figure 1. Analyse the information presented in Figure 1 and explain how this information can be used to enforce Qos?
