Program Options

Pathloss version 6 is available in several options:

PL6B - 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 modules for terrain data, antenna heights, diffraction, transmission analysis and reflections - multipath analysis. These features are common to all program options.

PL6C - 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.

PL6I - 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. Support for FCC ULS data is included with the interference option. 

PL6T - 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.

There are 4 possible configurations for the Pathloss 6 program.

About Us

For over 30 years we have been developing and refining the Pathloss program. Beginning with Version 1.4 in the late 1980s, Pathloss was quickly adopted by Equipment Manufactures, Telecommunications, Coordination and Engineering Service Providers worldwide.
