This option combines the point to multipoint – local studies and interference options and adds area study analysis. PL5T – Interference, point to multipoint design, local and area studies Interference through passive repeaters is included in the calculation. The analysis can be carried out for all radio types in point to point and point to multipoint networks taking into account the duplex arrangement on PTMP radios. The subsequent receiver threshold degradation and increase in outage time is calculated for rain and multipath correlated fading. The interference option calculates the aggregate interfering level of all transmitters in a selected group. Additionally local coverage studies can be carried out centered on a base station using signal strength, fade margin or visibility as the display criteria. These are used for the automatic PTMP linking and design features. The point to multipoint design option adds multi-sectored base stations to the network display. PL5C – Point to multipoint design – local studies These features are common to all program options. This includes the design sections for terrain data, antenna heights, diffraction, transmission analysis and reflections – multipath analysis. The basic program consists of the network display and the automated linking and design features for point to point radio links. PL5B – Basic program – point to point link design The interim release of Pathloss version 5 is structured in the following options: Pathloss 4.0 Setup…….(already removed by me > Sory your are late ^-^) wiley_-_radio-frequency_and_microwave_communication_circuits_-_analysis_and_design Wiley_-_RF_and_Microwave_Wireless_Systems UMTS_RF_Planning_Guidelines_v37_EricssonĮ.

Where the division is divided into areas A through Q.įigure 3.1 Regional Distribution According Rain Pn.837 ITU-R-1 Usually recommendations for rain area is often used by ITU-R Pn.837-1. Before the implementation of network, designers networks must be able to predict the possibility that will occur in loss-free channel. Then rain units are expressed in millimeters per hour. Before discussing the method of calculation of these losses is necessary to a discussion of information about the rain issue. The addition of this signal attenuation occurs at a total loss of transmission lines that use the media not guided ( used air media). When radio communications network designed Line of sight, the main thing noticed was the addition of the signal attenuation due to rain.
