In an 802.11 2.4 GHz system, what 22 MHz channels are considered non-overlapping?

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

When antenna gain is reported in dBi, the gain of the antenna is compared to what theoretical radiator?

You support a WLAN using dual-band 802.11ac three stream access points. All access points have both the
2.4 GHz and 5 GHz radios enabled and use 40 MHz channels in 5 GHz and 20 MHz channels in 2.4 GHz. A manager is concerned about the fact that each access point is connected using a 1 Gbps Ethernet link. He is concerned that the Ethernet link will not be able to handle the load from the wireless radios. What do you tell him?

What 802.11 network configuration would result in multiple stations broadcasting Beacon frames with the same BSSID but with different source addresses?

When a client station sends a broadcast probe request frame with a wildcard SSID, how do APs respond?

As an RF wave propagates through space, the wave front experiences natural expansion that reduces its signal strength in an area. What describes the rate at which this expansion happens?
