Site Survey Information

It is recommended to perform a site survey before installing the RDL-3000 equipment.
The data accumulated during this process is necessary to understand the operating
characteristics and obtain the best performance from the wireless system.

Planning Activities

4.1.1

RF Interference

Frequency planning is an essential component of installation and it is very important to
test for RF interference at every installation site. The RDL-3000 will not achieve full
operational capability if there is excessive interference on the same or adjacent RF
channel. Use the RDL-3000 built-in spectrum sweep feature to determine if a selected
RF channel is generally free from interference.
4.1.2

Path Profile

The path profile should include the following information:
Antenna
Location
Height
Azimuth
Elevation angle
Expected RSSI
The site survey should identify the optimum location for mounting the RDL-3000. For
maximum performance, there should be a direct line of sight between all communicating
wireless systems.

INSTALLATION GUIDELINES

Table 6: Site Survey - Path Profile Data

Description
Instructions that identify the location to install the antenna.
May include blueprints and specify material list.
Mounting height for antenna.
Horizontal aiming direction for the antenna (magnetic or GPS compass)
Vertical aiming for antenna (spirit level).
The expected RSSI value can be determined using the Link Budget Tool
available from Redline Communications.
