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

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

The Cisco Aironet 1140 Series Access Point draws 12.95 W at the power source. However， whenusing a long Ethernet cable， the device can draw up to how much additional wattage？（）

Which two methods can be used to prevent or reduce RFI from colocated directional antennas（）

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

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.

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

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

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？（）
