What is a site survey best practice for location-based services？（）

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

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.

What will cause wireless voice devices to perform poorly？（）

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

When conducting a wireless voice site survey， which two sizing considerations exist for thecoverage cell？（）

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

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 two Cisco antennas provide better isolation from RF sources that might be located behindthe antennas？（）

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