4 Planning considerations
During link planning, such factors as distance, obstacles and the link margin should be taken into account.We
strongly recommend to use the InfiPLANNER tool for link planning.
4.1 InfiPLANNER
InfiPLANNER is a link planning tool, which allows to design networks using InfiNet Wireless devices for optimal
deployment and cost effectiveness. Itaccounts fordifferentscenarios based on geography, distance, antenna
height, transmit power, device models and other factors. It outputs an installation report that defines the
parameters to be used for configuration, alignment and operation. Use the installation report to compare the
predictedperformance with theactual link performance.InfiPLANNER is available athttps://

4.2 Range and obstacles
Make sure that line of sight is providedwhen planning the antennas' placement for a point-to-point link in orderto
achieve maximum range and performance between two antennas. Perform a survey to identify all the obstructions
(such as trees or buildings) in the path and to assess the risk of interference.
The radio beam is an electromagnetic wave and it is not as thin as a laser beam, for example. The main energy in a
radio beam is concentrated along the straight line between the two antennas, inside an area with the shape of an
ellipsoid (or a rugby ball).This area is calledthe 1
st
Fresnel zone and its exact form and size depend 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 adecreased coverage range or performance.
Below is an incomplete list of possible obstructionsalong 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 mayobstruct the 1
st
Fresnel zone.
