Additional Outdoor Site Requirements
8. Using the Ohmmeter, measure and record the resistance of the required installation
to the grounding point. The resistance must be less than 1O ohm.
9. Review the results of the physical site survey. Decide if the site is suitable for the
wireless network installation.
• If the site is suitable, continue with stage 3, the RF survey
• If the site is not suitable, survey another site
Additional Outdoor Site Requirements
The ambient outdoor operating temperature should be ‐35 to 60C (‐31 to 140F).
Additional Indoor Site Requirements
The following requirements guarantee proper operation of the system:
• For IDU‐C units, allow at least 90 cm (36 ") of front clearance for operating and mainte‐
nance accessibility. Allow at least 10 cm (4 ") clearance at the rear of the unit for signal
lines and interface cables
• The ambient operating temperature should be 0 to 50°C (32 to 122 °F) at a humidity of
up to 90%, non condensing
Stage 3: RF Survey
The RF survey examines the wireless environment of the installation site, to determine
whether there are available channels within the radio operating frequency band. An RF
survey is performed using a spectrum analyzer.
It is advisable to familiarize yourself with the spectrum analyzer before going out on site,
specifically the Max Hold and Marker functions.
You should perform the RF survey at both proposed link sites.
The survey should be carried out during a busy time of day, to best judge the worst‐case radio
interference. Allow 2‐4 hours duration for a good RF survey.
It is possible to install the link and use the RADWIN Manager to find a clear
channel. Each frequency channel can be evaluated in turn. Achievement of a
clear channel is indicated by the marker in the Quality bar on the Channel
