Additional Outdoor Site Requirements
5. Determine a location for the indoor equipment; it should be as close as possible to
the antenna. At an existing site, there is probably an equipment room with cable‐
routing channels.
The IDU ‐ radio cable length limit is 100m, in accordance with 10/100BaseT
interface.
6. Measure and record the path length of the cable from the ODU position to the
indoor equipment room.
7. Determine the ground and lightning connection points of the installation. The ODU
and IDU must both be grounded.
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
3.5.1 Additional Outdoor Site Requirements
The ambient outdoor operating temperature should be ‐35 to 60C (‐31 to 140F).
3.5.2 Additional Indoor Site Requirements
The following requirements guarantee proper operation of the system:
•
For IDU‐C/IDU‐H/HP and RADWIN 2000i units, allow at least 90 cm (36 ") of front clear‐
ance for operating and maintenance 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
3.6 Stage 3: RF Survey
At this stage, you must examine 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.
Familiarize yourself with the spectrum analyzer before going out on site, specifically the Max
Hold and Marker functions.
Perform the RF survey at both proposed link sites.
