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？（）

In which three frequency bands does the Cisco Spectrum Expert Wi-Fi tool perform spectrumanalysis？ （）

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

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.

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

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

Which three colors are used in the Cisco WCS v5.2 Voice Readiness Tool？（）

For an active Cisco Unified Wireless IP Phone 7921G 5 GHz site survey， what are the mostappropriate client test settings to use with the AirMagnet site survey tool？（）

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

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？（）
