Cisco recommends a decibel referenced to 1 milliwatt signal level for the coverage cell edge at thepredetermined data rate that is needed to support the VoWLAN device and call capacityrequirements. What is that signal level value for Cisco Unified Wireless IP Phones 7920， 7921G， and7925G？（）

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

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 items should the site survey documentation include？（）

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

Which format can NOT be imported into Cisco WCS Planning Tool？（）

How should the transmit power on an access point and client each be set during a site survey？（）

How is attenuation measured？（）

What does a broad-spectrum interferer lower？（）

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.
