R. Alok K. Tiwari, of Idea Cellular Ltd., has graciously made this "Transmission Link Planning" workbook available. The following text is provided by Mr. Tiwari:
Click to download:
Important: If the file name is changed from the supplied "Link Planning Tool.xls," some of the macros will not function properly. It would be best to save the completed workbook under a new name, then start on new systems with the original file.
Here is the description for using the utility:
1. We mainly enter the parameter value into the
sheet "Calculations".
a. Entries shown in YELLOW cells are
mandatory.
b. Entries shown in GREY cells are to play with in order to
get the desired result wrt Standard Link Design Criteria.
c. Entries shown in SEA GREEN are ONE-TIME entries like
temperature, pressure etc.
DISCLAIMER: Use of this UTILITY is not intended for any commercial set-up. The author is not responsible for any type of damage occurred due to implementation of the results obtained from this utility to any commercial set-up.
PASSWORDS:
Sheet "Calculations" : Password "link"
Sheet "Antenna Heights": Password "antennae"
Sheet "Report": Password "report"
Sheet "DB_Ant1(18Ghz)": Password "antennae"
Sheet "DB_Ant2(15Ghz)": Password "antennae"
Sheet "DB_RadioEqpt": Password "radio"
Sheet "PassiveRepeater": Password "passive"
Above Passwords are activated into the file attached to this mail.
Please be careful while making any change to Sheet "Calculations" for it contains the most important formulae.
The "Calculation" sheet looks up for the required data :
a. For Antennae (of 18 GHz band) from the sheet:
"DB_Ant1 (18GHz).
Using the Password sizes and gains can be
modified.
Note that only FOUR sizes are permissible to
provide into this sheet.
b. For Antennae (of 15 GHz band) and Frequency of
Operation from the sheet:"DB_Ant2 (15GHz).
Using Password sizes and gains can be modified.
Note that only FOUR antennae sizes EIGHT Frequencies in TWO separate bands
can be used.
Also do not change the frequency named F1,F2,....F6,G1,G2. Only their respective
values can be changed.
c. For Radio Specific Data form the sheet:
DB_RadioEqpt.
Using Password we can also modify the Radio Names, their signature data and
Radio Parameters. Here THREE different type of Radios can be used.
2. The Sheet "Antenna Heights" is to calculate the antennae heights
based on LOS survey feedback data.
3. The Sheet "Report" is just the
compilation of information used in
link implementation.
This is to bring to your kind notice that formulae used into this workbook are as per ITU-T.As I'm using the Tool like Nokia's NETACT PLANNER and CTE's PATHLOSS, I've observed the similar results at least for Link Design parameters.
