NETWORK MODULE |
|
The Network module
provides a geographic interface to the path design modules simply
by clicking on the link between two sites. This feature significantly
reduces the design effort on large projects. Intra system interference
calculations are carried out in the Network module.
|
|
| |
|
|
|
| SUMMARY
MODULE |
|
| The
Summary Module is the default startup display in the Pathloss program
and provides a central location for the entry of path data parameters
and the interface. |
|
| |
|
|
|
| TERRAIN
DATA MODULE |
|
| A terrain database is required for
area coverage analysis, OHLOSS calculations in interference analysis
and the terrain view feature. Single path profiles can also be generated
from a terrain data base. |
|
| |
|
|
|
| ANTENNA
HEIGHTS MODULE |
|
| This
module determines the antenna heights which satisfy a clearance
criteria specified as an earth radius factor (K), a percentage of
the first Fresnel zone radius and an optional fixed height. Two
separate clearance criteria can be specified for both main and diversity
antennas. |
|
| |
|
|
|
| WORKSHEET MODULE |
|
| A
complete transmission analysis is carried out in the Microwave Worksheet
module. The data entry forms are accessed by clicking on an equipment
icon. The worksheet is calculated and the results are displayed
as the data entry proceeds. |
|
| |
|
|
|
| MULTIPATH MODULE |
|
| Ray tracing techniques are employed
to analyze the reflective characteristics of a path and to simulate
abnormal propagation conditions. The display operates in two modes. |
|
| |
|
|
|
| REFLECTION MODULE |
|
| The Reflection module analyzes the
variation in receive signal level on paths whose geometry can support
a specular reflection. |
|
| |
|
| DIFFRACTION MODULE |
|
| A diffraction loss calculation first
characterizes the terrain |
|
| |
|
| AREA COVERAGE MODULE |
|
| An area coverage analysis requires
a terrain data base. |
|
| |
|
| PRINT PROFILE MODULE |
|
| A
flat earth display with the earth radius factor (K) represented
as secondary profiles above the flat earth. The Fresnel zones
are displayed on the rays between the antennas. Four different
values of K and Fresnel zone references can be displayed.
|
|
| |
|
| TERRAIN VIEW |
|
three dimensional
terrain view is available in the Terrain Data and Network modules.
In the Network module, the user simply defines a rectangular area
on the screen to display the terrain. New sites can be added in
the terrain view.
|
|
| |
|
| SITE DATABASE |
|
| All options of the program include
an interface in the Summary and Network modules to a site database.
Any number of site databases can be created. |
|
| |
|
| INTRA SYSTEM INTERFERENCE |
|
| Interference calculations carry
the analysis down to the composite threshold degradation of the
victim receivers due to multiple interferers. In conjunction with
the Microwave Worksheet you can see the effect of the interference
on outage times. |
|
| |
|
| ANTENNA and RADIO DATA FILES |
|
| A microwave interference analysis
requires horizontal radiation pattern envelopes for the four
polarization combinations (HH, VV, HV and VH). The same information
is required for point to multipoint applications where the base
antenna has a fixed orientation. |
|
| |
|
| TERRAIN DATABASES |
|
| A terrain database is required for
area coverage analysis, OHLOSS calculations in interference analysis
and the terrain view feature. Single path profiles can also be generated
from a terrain data base. |
|
| |
|
| REPORTS |
|
| All modules include a report selection
with a print preview showing the pagination and can include your
company logo. The reports can be printed or copied as formatted
text into your word processor. All of the profile screen displays
can also be copied to create custom reports. Reports can be
save in either RTF (Rich text format) or as ASCII text files. |
