Determine the Tx/ATA and Rx/ARA Antennae Placement:
1) Using the “Pre-installation Survey Check-list” and the store floor plan, walk the store
and determine the location for the placement of the Tx/ATA and Rx/ARA antennae for
both the sales floor and the stock room. Refer to “
Appendix A - Antenna Placement”
of this guide for more detailed information on the placement of each antennae.
2) The location for each Tx/ATA and Rx/ARA marked on the floor plan is the
recommended location for each antenna. The actual location is determined by issues
found at the suggested location during the survey. The actual location normally should
not be more than one tile over from the designated location. The following rules must
be used to determine the actual antennae placement.
 The Tx/ATA antenna must have a clean line of sight to the floor. It can not be over
shelves or display tables.
 The Rx/ARA antenna should have a clean line of sight to the floor, but it can be
over a display table. It can not be over shelves.
 Tx/ATA antennas over the sales floor must be installed on a full ceiling tile.
 Rx/ARA antennas can be installed on a partial tile but the tile must be square or
rectangular, it can not be installed on a specialty cut tile. Install on a full tile if
possible.
 Nothing else can be installed on the same tile as a Tx/ATA or Rx/ARA. This
includes but is not limited to:
o A/C vents
o Sprinkler heads
o Security cameras
o Security screens
o Emergency lighting
o Speakers
 Each antenna must be a minimum of 10 feet from another antenna.
 If the location for Rx-5 and Rx-9 must be adjusted, skew it towards aisle 1.
 If the location for Rx-8 and Rx-12 must be adjusted, skew it towards the last aisle;
normally that is aisle 9 or 10.
 There must be access in the ceiling to install the antenna and to meet the
installation requirements for that antenna.
 If there is a problem determining the location of the antenna, then check with the
Help Desk.
3) When reviewing the locations of the Rx/ARA antennas along the back wall of the store,
look to see if mirrors are present. If mirrors are present; refer to Back Wall Antenna
Placement Issues found in
Appendix A - Antenna Placement. This section
describes how mirrors affect the placement of Rx-9, Rx-10, Rx-11 and Rx-12 along the
back of the store.
