Pathloss 5.0

[/spoiler][spoiler=open this] for Description:

Program options

Pathloss version 5 is available in several options:

PL5B - Basic program - point to point link design

The basic program consists of the network display and the automated linking and design features for point to point radio links. This includes the design sections for terrain data, antenna heights, diffraction, transmission analysis and reflections - multipath analysis. These features are common to all program options.

PL5C - Point to multipoint design - local studies

The point to multipoint design option adds multi-sectored base stations to the network display. These are used for the automatic PTMP linking and design features. Additionally local coverage studies can be carried out from a base station using signal strength, fade margin or visibility as the display criteria. In addition to the Pathloss deterministic diffraction algorithms, local studies can be carried out using the F(50,50), F(50,90), F(50,10) curves, Okimura (Hata) and Cost (Hata) empirical algorithms.

PL5I - Interference

An interference analysis can be carried out between groups of links in the network display or between a network display group and the Pathloss site database for all radio types. For each receiver, the aggregate interfering level of all transmitters is calculated. The receiver threshold degradation and the resulting increase in the outage probability is then determined taking into account the fade correlation for rain and multipath fades. Interference through passive repeaters is included in the calculation.

PL5T - Interference, point to multipoint design, local and area studies

This option combines the point to mulitpoint - local studies and interference options and adds area study analysis. In a local study each base station has its own coverage centered on the base station. In an area study, signals from a number of base stations are calculated into a common area. In addition to receive signal levels, an area study can display the most likely server, carrier to interference and simulcast delay.

Program organization

All operations are centered around the network display which provides a geographic layout of sites and links. The following backdrops are available in this display:

Geo-referenced imagery in bmp, png, jpg and tif file formats. The geo reference information can be obtained from external text files (Planet type), MapInfo tab files, directly from geo-tiff files or can be manually geo referenced directly in the program.

Vector data in ESRI shapefile or Planet formats.

Elevation displays in a flat and shaded format. The elevation ranges, absolute- relative settings, colors, and transparency are completely configureable.

A 3 dimensional elevation display showing the Fresnel zone radius on links. Pan, zoom and the view point control allow the user to effectively fly along a path.

Clutter displays. The color legend and overall transparency are completely configureable

The Pathloss program contains two separate applications as follows.

PL50 - network display and integrated link design sections.

PL50L - link design sections only

In the network display, the link design sections are accessed by clicking on the specific link. It is not possible to access the link design sections for a link which are not associated with the network display using the standard open file dialog. The stand-alone PL50L link design application is used for this purpose.

Network display operations

Operations are based on groups or a selection of sites and links. A selection is a temporary group. There can be any number of named groups and these can overlap other groups. Groups of links can be automatically created based on path length, frequency and fade margin The default group is all sites and links. The following operations are carried out in the network display.

Interference calculations between two groups of links in either or both directions. One of the groups can be the Pathloss site database

Automatic point to point linking - generate all possible links between two groups of sites and determine the final configuration based on path length, antenna heights, diffraction loss or fade margin.

Automatic point to multipoint linking - generate links from a base station to a group of sites or all sites within a specified radius and determine the final configuration based on path length, antenna heights, diffraction loss or fade margin. Remote sites are linked to the best sector at the base station.

Automatic link design - specify the equipment parameters and the design methods and algorithms for a group of links and generate path profiles and carry out a complete transmission analysis. This feature is also used in the automatic point to point and point to multipoint linking.

Point to point channel frequency and polarization assignments

Network performance analysis

Passive repeater design

Local and area studies

Report generation for a group of links. Any combination of report options can be printed for the selected group
