The goal of the WallPlate site survey is to

determine the average RSSI loss through one room/wall combination
Provisioning the WallPlates
• Order the number of WallPlates according to the RSSI loss through one room/wall. If the
floor material is the same as the walls e.g. concrete, then the vertical loss will be similar
(usually +3dB to +6dB). Offset the installation with each floor so that WallPlates are not
stacked vertically above one another.
• Order 5% extra WallPlates for coverage in non-standard areas of the hotel; such as
rooms blocked by an elevator shaft. During the installation, if coverage holes exist, plug
the hole by installing an extra WallPlate.
Once the typical RSSI loss through a hotel is determined, site surveys at similar hotels become
unnecessary as the same plan can be used repeatedly.
WallPlate Density Chart
Based on the RSSI loss from one room/wall, order the indicated number of WallPlates, plus 5%
margin.
RSSI loss is… Horizontal WP density Vertical WP offset
>30dB One every three rooms Install offset one room
>20dB and <30dB One every four rooms Install offset two rooms
>10dB and <20dB One every four to six rooms Install offset three rooms
<10dB One every eight rooms Install offset four rooms
