The Site Survey Team will assess and report on any existing tower or
antenna framework that may be usable.
In the case of a rooftop location, a standard non–penetrating mounting with a
1.8 m antenna pole is standard. Non–penetrating mounts require concrete
building blocks to prevent movement which might affect the alignment of the
antennas.
The Site Survey team may determine that a wall–mounted antenna provides
the optimum LOS.
The Site Survey Team will also identify the best place for the ODU and
optional IDU (L2SW module). Factors that need to be considered include:
• Accessibility - For installation and maintenance purposes, optional IDU is
installed to 19-inch rack and should be readily accessible from both the front
and the rear.
• Environment - Optional IDU is designed to operate in temperatures ranging
from –33 ℃ to +55 ℃, and in relative humidity of 95% non–condensing.
• Cables - The Site Survey Team will determine the path for the optical fiber
cable, power supply/alarm cable and LAN cable(s).
In the case of a rooftop installation, the Site Survey Team will locate any
available portal conduit to the roof. If none is available, the Site Survey Team
will prepare a recommendation and include it in the report.
The Site Survey Team will determine the proposed length of the above
cables between ODU/IDU and external equipment. A further 10% of this
measurement is required to allow for service loops and contingencies.
• Power Supply - The Site Survey Team will determine the location and
availability of a power source. The E-Band ODU radio is designed to operate
with a DC power supply from –40.5 to –57 Vdc or AC power supply is
designed to operate 100 to 240 Vac. A dedicated wall outlet is required.
