A customer is looking to install a new Motorola Solutions wireless infrastructure along with purchasing new Motorola Solutions 802.11a/b/g mobile computers for a warehouse. Your account team has recommended the Motorola Solutions RFS6000 with AP650 s because of the latest S02.11n technology. The customer has asked what the benefit would be by putting in an 802.11n wireless infrastructure when they aren't using 802.11n clients. You are preparing a justification. All of the following are valid responses, EXCEPT:

• A.802.11n is backward compatible to legacy 802.11a/b/g clients.
• B.802.11n provides a larger coverage area for legacy 802.11a/b/g clients at higher data rates (36Mb/s, 54Mb/s).
• C.Installing an 802.11n infrastructure provides better TCO and scalability for any future 802.11n clients that are added later.
• D.An 802.11n wireless infrastructure automatically upgrades the radios in the mobile computers to 802.11n and allows them to take advantage of all the 802.lln features.

When mounting an antenna on a metal wall, what special considerations do you have to take into account regarding RF propagation (select TWO)?

• A.Type of screws to be used
• B.The distance the antenna is from the wall
• C.The type of antenna to be used
• D.Length of antenna cable
• E.Mounting height of the antenna

After the site survey and installation are complete, you perform a spot check to ensure performance compliance with the site survey. Which of the following should NOT be verified in this spot check?

• A.Is throughput what was expected?
• B.Is the actual coverage as expected?
• C.Is the data properly secured?
• D.Is roaming operating as predicted?

After setting up the WLAN according to the site survey, you observe unanticipated RF interference which can be neither eliminated nor avoided. In this situation what could be done to mitigate the effect on throughput?

• A.Adjust fragmentation to require larger frames
• B.Eliminate all security mechanisms
• C.Change the network type to an IBSS
• D.Adjust fragmentation to require smaller frames

You have configured Radio 2 (5 GHz) of an AP-650 to use 802.11n 20/40 MHz channels. Under the WLAN configuration settings you have selected WPA/WPA2-TKIP using a PSK. To test the connection you associate an 802.lln client laptop device but notice that the connection speed between the two 802.11n devices is limited to 54 Mbps. See Exhibit:
B.3.2.06 at the bottom. Which of the following is the most likely reason for this condition?

• A.PSK is limited to 54 Mbps.
• B.802.11 Protection Mechanisms are in effect.
• C.More wireless client devices are using 802.11a than are using 802.lln tipping the AP into legacy compatibility mode.
• D.WPA/WPA2-TKIP encryption is limited to 54 Mbps.
• E.Channels in the 5 GHz band are limited to 802.11a rates of 54 Mbps.
