You are evaluating access points for use in the 5GHz frequency band. What PHY supports this band and supports 80 MHz channels?

You have been tasked with creating a wireless link between two buildings on a single campus. The link must support at least 150 Mbps data rates. What kind of WLAN technology role should you deploy?

You administer a small WLAN with nine access points. As a small business, you do not run a RADIUS server and use WPA2-Personal for security. Recently, you changed the passphrase for WPA2-Personal in all APs and clients. Several users are now reporting the inability to connect to the network at times and it is constrained to one area of the building. When using a WLAN scanner, you see that the AP covering that area is online and has a strong signal. No other changes have been made to the environment and all access points are the same model. What is the likely problem?

You are performing a post-implementation validation survey. What basic tool can be used to easily locate
areas of high co-channel interference?

An 802.11 WLAN transmitter that emits a 50mW signal is connected to a cable with 3dB of loss. The cable is connected to an antenna with 16 dBi of gain. What is the EIRP power output?
