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.

In an outdoor bridge link， what is calculated by using this formula： transmitter power + antennagain - insertion OR cable loss（）？

Given the correct input parameters， the Cisco WCS Planning Tool can calculate a recommendedaccess point count for which three uses？ （）

What does a broad-spectrum interferer lower？（）

By how much is a signal’s strength reduced when the signal passes through an object thatintroduces 3 dB of attenuation？（）

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

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

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？（）

A design requires 100 access points with high channel bandwidth and disabled lower data rates.How are the data rates set on the Cisco WLC and Cisco WCS？（）

Which three device types are identified by Cisco Spectrum Expert Wi-Fi finding an Avg PulseDuration parameter？（）
