What phrase defines Equivalent Isotropically Radiated Power (EIRP)?

• A.The power output from the radio after cable losses
• B.The highest RF signal strength that is transmitted from a given antenna
• C.The power output from the radio into the RF cable
• D.Reflected power due to an impedance mismatch in the signal path
• E.Power supplied from the transmission line to the antenna input

You are configuring an access point to use channel 128. What important fact should be considered about this channels?

• A.It is a channel that is unsupported by most access points
• B.It is a channel that likely requires DFS when used
• C.It is a 22 MHz channel so it will overlap with the channels above and below it
• D.It is a 2.4 GHz frequency band 40 MHz channel, so it should not be used

The BSA of an AP covers the area used by the sales and marketing department. Thirty-five stations operate in this space. The user indicate that they need more throughput and all stations are 5 GHz capable 802.11ac clients. The current AP configuration uses 20 MHz channels in both
2.4 GHz and 5 GHz. What is the least expensive solution available for increasing throughput for these users without implementing configuration options that are not recommended?

• A.Use a 40 MHz channel on the 5 GHz radio
• B.Install a second AP in the coverage area
• C.Use a 160 MHz channel on the 5 GHz radio
• D.Use a 40 MHz channel on the 2.4 GHz radio.

What term describes the effect of increasing the intensity of an RF wave with an antenna by focusing the energy in a specific direction?

• A.Distributed Radiation
• B.Passive Gain
• C.Beam Compression
• D.RF Flooding
• E.Active Amplification

A WLAN transmitter that emits a 50 mW signal is connected to a cable with 3 dB loss.
If the cable is connected to an antenna with 9 dBi gain, what is the EIRP at the antenna element?

• A.26 dBm
• B.13 dBm
• C.10 dBm
• D.23 dBm
