PN 9000-10 Help Hot Line (U.S. only): 1-800-530-9960 5-21
620021-0 Rev. A
For reference, Tables 5-21 through 5-27 show the distance covered by an antenna for
various in-building environments. The following assumptions were made:
• Path loss Equation (3)
• 6 dBm output per carrier at the RAU output
• 3 dBi antenna gain
• RSSI = –85 dBm (typical for narrowband protocols, but not for spread-spec-
trum protocols)
