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？（）

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？（）

How is attenuation measured？（）
