Pathloss 5 Crack Full.27
Dayna Delabarre
Pathloss data file (pl4) locking and Network file sharing (gr4) has been added to improve working with shared files on a network. See thedocumentation filelock.pdf on www.pathloss.com. A private directory can be specified to carry out interference calculations
The pathloss program saves all calculations including Fresnel zones, reflective planes, diffraction loss and reflection analysis. File corruption problems have been reported from time to time due to these calculations. This problem has been corrected.
The clearance display in the antenna heights module used in VHF-UHF applications would use the second set of clearance criteria which could only be accessed when a microwave application was active. The Gauss Kruger coordinate system has been implemented asa generalized Transverse Mercator projection. See the document gauskrug.pdf on the CTE web site for details (www.pathloss.com)
String values are now enclosed in "". It has been reported that not all fields print; however, this problem has not been simulated. Interference Case Detail Report The modify - pathloss data file function did not carry out the following:
An update pathloss data files feature has been added to enter the threshold degradations into the individual pl4 files. This feature is accessed in the case detail report. Select Modify - Pathloss data files. The composite threshold degradation and the number of interference exposures will be added to the worksheet data. Microwave antenna patterns supplied by Andrews in the new NSMA format do not include the FSTLST field in the RPE data. The file conversion to the binary MAS format will ignore this value if it is missing instead of giving an incompatible file format error.
The initial format for these files was taken from "NSMA 16.2.4" and is described in the pathloss documentation. A newer format "NSMA WG16.99.050" is now also supported. The documentation for this format is available from www.nsma.org. All ascii VHF-UHF antenna data files have been converted to the new format.
The terrain view color ramp has changed and a color legend has been added. This release corrects the following problems: Loading a pathloss data file in the terrain data module, could result in a display with the structures drawn above the profile. The workaround was to change to another module and then return to the terrain data module. Long file names (40 characters not including the full path) could cause problems in the network module. The reflective plane used in the reflection module could result in an invalid plane if the cancel button was clicked after the plane had been defined.
3.0 template files are now supported in version 4.0. The procedure is to load the template file using the Files - Open menu selection. This step reads and converts the version 3.0 template file to a standard Version 4.0 file. If the template will be used in an interference calculation, edit the template file as required to include the antenna and radio codes and the T to I and 10-6 BER thresholds. Save the file. The extention tpl is no longer used in version 4.0. Any pathloss data file can be used as a template. Multi Site Area Coverage Adding a new site in a network site list which contained an active coverage caclulation could cause a program crash. Oahu USGS 7.5 minute terrain database The 1.5 minute shift in the longitude for the 7.5 minute maps for the island of Oahu has been taken into account.
The conversion of USGS 7.5 minute DEMs now handles 10 meter horizontal spacing. Previous builds were limited to 30 meters. Field strength calculations in the VHF-UHF worksheet and coverage module has been changed to the definition in ITU-R PN.525. The results are now identical to pathloss version 3.0. The results of previous builds will be approximately 2.2 dB different. The north - south reference arrows on coverage displays were not positioned at the radial ends on segmented displays. On coverage displays using field strength criteria, the mobile antenna gain is not included in the legend. The parameters box in the print profile module would display diversity fresnel zone references on non diversity applications.
Clicking on a site legend or link, in cases where the sites of links overlapped, resulted in the selection of the first site. If multiple sites or links are detected, a selection is now presented to the user. When a pathloss data file is imported into the site list, the file name will always be updated, even if the link already exists.
The pathloss program requires a default printer to access the network and coverage modules which determine the page size from the default printer. Additional error checking has been added to determine if a default printer exists.
Abstract:In Wireless Sensor Networks which are deployed in remote and isolated tropical areas; such as forest; jungle; and open dirt road environments; wireless communications usually suffer heavily because of the environmental effects on vegetation; terrain; low antenna height; and distance. Therefore; to solve this problem; the Wireless Sensor Network communication links must be designed for their best performance using the suitable electromagnetic wave behavior model in a given environment. This study introduces and analyzes the behavior of the LoRa pathloss propagation model for signals that propagate at near ground or that have low transmitter and receiver antenna heights from the ground (less than 30 cm antenna height). Using RMSE and MAE statistical analysis tools; we validate the developed model results. The developed Fuzzy ANFIS model achieves the lowest RMSE score of 0.88 at 433 MHz and the lowest MAE score of 1.61 at 433 MHz for both open dirt road environments. The Optimized FITU-R Near Ground model achieved the lowest RMSE score of 4.08 at 868 MHz for the forest environment and lowest MAE score of 14.84 at 868 MHz for the open dirt road environment. The Okumura-Hata model achieved the lowest RMSE score of 6.32 at 868 MHz and the lowest MAE score of 26.12 at 868 MHz for both forest environments. Finally; the ITU-R Maximum Attenuation Free Space model achieved the lowest RMSE score of 9.58 at 868 MHz for the forest environment and the lowest MAE score of 38.48 at 868 MHz for the jungle environment. These values indicate that the proposed Fuzzy ANFIS pathloss model has the best performance in near ground propagation for all environments compared to other benchmark models.Keywords: fuzzy ANFIS; wireless sensor network; near ground; LoRa; pathloss propagation model; RSSI; jungle; forest; open dirt road
