Microwave Pro |
Microwave Pro uses the
FCC's ULS database to identify usable microwave frequencies and to examine
paths over terrain elevation plots while acknowledging interference to and
from other microwave links. The program uses
terrain based analysis in conjunction with methodology found in TIA-EIA
Telecommunications System BulletinTSB10-F. When supplied with the parameters for a proposed path,
Microwave Pro can quickly load all stations that have a potential interference
relationship and calculate Carrier to Interference (C/I) ratios. A list of contact
information for paths within the "keyhole" radius from the proposed
path can be generated to be used in the prior notification process. The
screen below shows the study of a single link on 950.5 MHz. The C/I In
and C/I out columns show the carrier to interference ratio in dB for
"outgoing" and "incoming" signal relationships, while
the margin columns show the difference between the desired C/I ratio and the
available C/I ratio. |
The
paths below show the relationship spatial relationships between the new
path, D to E, and the existing path from A to B (Both shown in green).
Possible interfering paths are shown in red between A to E and D to B. |
The
profile shown below graphs the actual path over terrain. The terrain
elevation is graphed in red, while the path is plotted in green and the
fresnel zone in orange. |

Microwave-Pro also has a built in link budget system
analysis tool that can be used to generate complete link budget report. The 'wizard'
based interface allows the user to enter path information, transmitter power,
antenna gains, and other system gains and losses. The program will calculate
the EIRP, path loss, fade margin, and provide a minimum recommended fade margin.
A sample link budget report may be downloaded here
(PDF format). Pictures of the Link Budget Wizard may be seen below: |

Other Key Features of Microwave-Pro include:
- Calculates C/I ratios that consider terrain obstruction.
- Can plot terrain profiles of all protected and interfering paths.
- Includes a pattern library for specifying many common antenna patterns.
- Gives a graphical representation of both protected and interfering path geometry.
- Can search both license and application microwave databases.
- Can perform a frequency search study for the 944 MHz BAS band to determine available frequencies.
- Can generate address information needed for PCN coordination letters.
