What should be done if Cisco Spectrum Expert Wi-Fi reports a channel utilization of 40 percent onchannel 36， from a source outside of the site？（）

How is attenuation measured？（）

According to the following statement， can you tell me which term is described？（）It is the air return for an air conditioned system. In most buildings， the area above a drop ceiling orunder a raised floor is used as the air return （source of air） for the air conditioning. Those dropceiling and raised floors are also where wire is often installed. If wire and cable is installed in a dropceiling or raised floor， it is out of sight. If that cable were burning， it would give off toxic fumes.These would be fed to the rest of the building by the air conditioner. As a result， people could beinjured even though they are a long way from the fire.

When surveying for VoWLAN， which power level should you base the access point coverage designon？（）

When planning for voice deployments with the Cisco Unified Wireless IP Phone 7921G handset in amultifloor building with a WLAN that operates at an 11 MB/s data rate， how many decibelsreferenced to 1 milliwatt of same-channel separation are recommended between floors？（）

Which can NOT be selected for supported services in Cisco WCS Planning Tool？（）

When using a lightning arrestor， connect which type of ground wire to a good earth ground？（）

What does a Cisco Unified Wireless IP Phone 7921G deployment require（）？

When planning for VoWLAN capacity during a site survey， how many simultaneous calls can beestimated per 5 GHz channel？（）
