a mesh network and generate a list of RF links associated with the
network.
Be sure to note or mark up any changes to position of devices, or
the introduction of new devices, created during the survey.
NOTE: Do not run more than one RF interface (dongle) at a
time in an area during a site survey .
What to take to a Site Survey
The following equipment is the minimum that will be required to
carry out an RF site survey.
●
PC/Tablet running the AgileIQ™ RF PC Tools software application
●
USB RF interface (Dongle)
●
Two Agile™ radio sensors in RF bases
●
Set of Duracell 123 batteries
System Sensor can supply a range of additional equipment to
assist with the site survey.
Available options are:
● POLE HWKIT - 1.5m – 5.2m Telescopic pole
● CUP HWKIT – Cup to hold Agile™ radio device and base in
position on pole
● SOLOADAPT HWKIT – Adaptor that allows the CUP HWKIT to
be connected to a SOLO* access pole
● BAG RF HWKIT – Survey bag to store and carry poles and
cups etc.
* Available from Detection Testers/No Climb.
Note: The USB interface may need a mini-USB adaptor to be used
with a Notebook/Tablet.
The picture shows a device holder (CUP HWKIT) mounted on an
extension pole (POLE HWKIT).
Summary of Basic RF Site Survey Principles
1) Site diagram:
Obtain or create a facility diagram or floor plan
drawing that depicts the location of walls, walkways, etc.
2) Visual inspection:
Walk through the facility to verify the
accuracy of the facility diagram. Add any potential barriers that
may affect the propagation of RF signals such as metal racks
and partitions, items that are not shown on the floor plan.
3) Device positions:
Determine the preliminary location of
devices; be certain to consider mounting options. Make
sure all doors and windows etc are closed when the survey
measurements are taken.
4) Verify RF link quality:
Take note of signal readings at the
different device locations, moving through the site. (In a multi-
level facility, perform signal checks on the floors above and
below.) Based on the results of the testing, it may be necessary
to relocate some devices and redo any affected tests. Where
appropriate, introduce an additional device or a repeater to
form a bridge between two locations with a weak link.
5) Document the findings:
Once satisfied that the planned
location of devices will have adequate link quality, identify them
clearly on the facility diagrams and add all relevant notes to the
project; the installers will need this information. Also, provide
a log of signal readings for reference and as support for any
future network additions or redesign.
The use of the Agile IQ™ software application will provide a high
level of assistance in accomplishing these tasks quickly and
efficiently.
