XYZ Corporation is experiencing connectivity problems with their existing building-to-building bridge link. A concrete wall on the roof of one building is partially blocking the Fresnel Zone, and the connection is dropping many frames. The administrator moves the antenna to an area not obstructed by the concrete wall and then realizes the RF cable cannot reach the new location.
If an extension cable is added to move the antenna, what are the likely results?
What statement about 802.11 WLAN performance is true?
What is the intended use for the WLAN hardware known as a pole or mast mount unit?
What phrase defines Equivalent Isotropically Radiated Power (EIRP)?
What HT technology requires MIMO support on both the transmitter and receiver?
In addition to throughput enhancements, what other improvements does a dual-band 802.11ac AP provide when compared with 802.11a/g APs? (Choose 2)
ABC Company has thousands of Wi-Fi users accessing their network on a daily basis. Their WLAN consists of 700 access points, 6 WLAN controllers, and a wireless network management system.
What network functions are performed by the enterprise-class WNMS? (Choose 3)
ABC Company has just purchased a 6 dBi patch antenna. After performing some tests with the 6 dBi antenna, they have concluded that more antenna gain is needed to cover their outdoor courtyard. When choosing an antenna with higher gain, what other antenna characteristic will also always change?
A WLAN transmitter that emits a 200 mW signal is connected to a cable with 3 dB loss.
If the cable is connected to an antenna with 10 dBi gain, what is the EIRP at the antenna element?
What WLAN system feature is required to produce a scenario with the following configuration on a single access point? (Choose 2)
1. SSID = Guest / BSSID = AA:AA:AA:AA:AA:AA /
VLAN = 22 / Subnet = 192.168.22.0 / RF Channel = 6
2. SSID = Corporate / BSSID = BB:BB:BB:BB:BB:BB /
VLAN = 33 / Subnet = 192.168.33.0 / RF Channel = 6 / User Type A
3. SSID = Corporate / BSSID = BB:BB:BB:BB:BB:BB /
VLAN = 44 / Subnet = 192.168.44.0 / RF Channel = 6 / User Type B
What statement is true concerning the use of Orthogonal Frequency Division Multiplexing (OFDM) in IEEE 802.11 WLANs?
