23
- Do not stay on the roof top in windy or rainy weather, during thunderstorms or when
the working zone is covered with snow or ice.
- Do not touch the antennas, antenna poles, cables and lighting arrestors during
thunderstorms
- Antenna cable must be grounded at all times.
In case of failure, any manipulation of the equipment is allowed to trained personnel only.
3.2. Equipment Positioning Guidelines
3.2.1. Antenna Placement
When selecting an antenna placement for PTP link, in order to obtain the
maximum link range and performance, LOS must be clear for the path between the
two antennas.
The radio beam is an invisible form of electromagnetic wave propagation and is not
as thin as, for example, a light (or laser) beam. The main energy in a radio beam is
concentrated along the straight line between the two antennas, inside an area the
shape of an ellipsoid (or a rugby ball). This area is called a 1
st
Fresnel zone and its
exact form and size depends upon the frequency and the signal propagation path
length.
If most of the 1
st
Fresnel zone is obstructed, a major part of the radio wave’s
electromagnetic energy is lost, which leads to a severe signal quality degradation
and, as a result, to decreased coverage range or performance.
Below is an incomplete list of possible obstructions on the signal propagation path:
Neighboring buildings
Trees
Bridges
Power lines
To obtain the best results, it is necessary to perform a precise analysis of the
signal propagation path and possible obstructions that may cover the 1
st
Fresnel
zone.
NOTE
For radio planning and path profile analysis, both the terrain model and clutter layer of
the area are required. These are typically provided by professional mapping vendors. For
details, please contact InfiNet Wireless.
Here are some general recommendations for antenna placement:
