Steps for wireless deployment Ø Survey existing Wi. Fi installation Ø Using Ekahau Site Survey Ø Survey the 2. 4 GHz band using spectrum analyser Ø e. g. Yellow jacket Ø Plan additional points based on required location accuracy Ø Wi. Fi tag needs to see 3 active AP’s for 1 to 10 m accuracy Ø Install AP’s Ø Check with Ekahau Site Survey Ø Program Ekahau Positioning Engine database © Daconi Ltd 2005
