Antennae Placement Issues over the Sales Floor
When determining the placement for both the Tx/ATA and Rx/ARA Antenna you may have
to slightly adjust the designated location from the store floor plan because of obstructions
existing within the store. The antenna should be placed on a ceiling tile as close as
possible to the designated location, normally within one tile.
Follow the rules listed
below to determine the correct location for the antenna placement because of
obstructions.
 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 the 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.
 Refer to “Back Wall Rx/ARA Antennae Placement Issues” in this Appendix for
more detail on the placement of the Rx/ARA antennas along the back wall of the
store.
On the following pages are examples of obstructions that affect antenna placement.
