  11. GIS Layer and Map Management (Generating Workarea) • Generate Workarea (from previously saved files) • Choose the Corresponding raster files and “Generate Workarea File” • Save file when prompted

  12. GIS Layer and Map Management (Adding Layers to GIS) [1/2] • Adding the Elevation and Clutter Layers to the GIS. • Go to Map Window Manager • Add the “Terrain Layer” and “Clutter Layer” from the Raster as shown

  13. GIS Layer and Map Management • The GIS should look like the following after zooming in (Without locations and links)

  14. GIS Layer and Map Management (Adding Layers to GIS) [2/2] • When you have the locations and paths imported into the tool (discussed later), you can add the layers as follows:

  15. Data Models • Network Elements • LOCATION • HUBSITES • SECTOR • PATH • PATHRESULT • Catalog Elements • FEEDER • REFLECTOR • ANETENNA • CHANNELPLAN • EQUIPMENT • ANTENNA SPLITTER

  16. Data Import • Importing csv Files • Prepare csv files according to the format accepted by MW Design Module • The import process should follow this order: • Catalog • Channelplan • Equipment • Antenna • Feeders, antenna splitters, Reflectors (if available) • Network • Locations (Sites) • Paths

  17. Data Import (Catalog: ChannelPlan) [1/3] • All Channel Plans csv format • Import all channel plans (one csv file)

  18. Data Import (Catalog: ChannelPlan) [2/3] • After importing the “all channelplans” csv files, They should appear in the left tree pane under CHANNELPLAN • Each channel plan can be either • Imported separately in csv file with the following format • Then click import button

  19. Data Import (Catalog: ChannelPlan) [3/3] • OR Added manually by clicking • ChannelPlanTable for 15 GHz, 28MHz

  20. Data Import (Catalog: Equipment) • After collecting all equipment files in one folder (.raf files), you can select all and import them as follows (special format). • When imported they should appear in the Left tree pane under EQUIPMENT

  21. Data Import (Catalog: Antenna) • After collecting all Antenna files in one folder (.dat/.adwfiles), you can select all and import them as follows (special format). • When imported they should appear in the Left tree pane under ANTENNA

  22. Data Import (Catalog: Feeders, Antenna Splitters, reflectors) • Similar procedure is followed to import feeders, reflectors, and antenna splitters. • Each of these has its own csv format • They should appear in the left tree pane afterwards

  23. Data Import (Network: Locations) [1/3] • Prepare locations to be imported with respect to the following csv format, • Import locations

  24. Data Import (Network: Locations) [2/3] • When importing location, you will be prompted to click the zone of interest (UK_Zone in our case) • Make sure OSGB 1936 is selected

  25. Data Import (Network: Locations) [3/3] • Locations in the left tree pane • Locations on the GIS (Blue Squares)

  26. Data Import (Network: Paths) [1/3] • Prepare Paths to be imported with respect to the following csv format,

  27. Data Import (Network: Paths) [2/3] • Import Paths (select csv file) • Paths in the left tree pane

  28. Data Import (Network: Paths) [3/3] • Paths on GIS (Yellow links)

  29. Add from GUI (Catalog Elements) [1/10] • Everything discussed so far can be done manually through the GUI interface. • ChannelPlan • Fill out the fields manually • Same applies to all Catalog items (Antenna, Equipment, Feeders, Antenna Splitters, Reflectors) with their corresponding information to fill out.

  30. Remove from GUI (Catalog Elements) [2/10] • Please note that in order to remove any channel plan, you must remove paths that are associated with the channel plan. • In order to remove an antenna/equipment from catalog, go to catalogue and delete equipment of interest.

  31. Add from GUI (Network Elements-Locations)[3/10] • Locations can be added from the GUI interface by clicking: • on any location in the LOCATION tree pane or “LOCATIONS” • A new Location window will open under “Detail Editor” to fill out the details

  32. Add from GUI (Network Elements-Locations)[4/10] 2. Right-clicking anywhere in the GIS (Map Window). • Enter location name and choose zone like earlier (UK_Zone)

  33. Add from GUI (Network Elements-Paths)[5/10] • Pathscan be added from the GUI interface by clicking: 1. Any site in the GIS window (Map window) • A dashed line will show up from the current site to connect to another site. Once connected, a window pops up to fill the path details.

  34. Add from GUI (Network Elements-Paths)[6/10] 2. on any path in the PATHS tree pane or “PATHS” • Select Path Type • A new Path window will open under “Path Editor” to fill out the details

  35. Add from GUI (Network Elements-Paths)[7/10] • The following information needs to be filled: • Site Information • Path configuration Based on your path configuration the “Diversity” and “Repeater” tabs get enabled. UK Rain Intensity File

  36. Add from GUI (Network Elements-Paths)[8/10] • In case of 1+0/HSB, the 1+0 Antenna and Equipment are assumed for the protection as well. • In case of FrequencyDiversity, the “Diversity Channel” field is enabled. • In case of SpaceDiversity,SpaceDiversityHS,Combined2RxDiversity, Combined4RxDiversity, and HSB+SD, “the Diversity” tab is enabled.

  37. Remove from GUI (Network Elements-Paths)[9/10] • Remove Path from GIS (multiple selection is possible) • Confirm action • Remove Paths from Tree Pane (multiple selection is possible) • Confirm action

  38. Remove from GUI (Network Elements-Locations)[10/10] • Before removing any Locations from the network, the connecting path must be removed first • Remove Location from GIS (multiple selection is possible) • Confirm action • Remove Locations from Tree (multiple selection is possible) • Confirm action

  39. Search Tool • To search for a particular Path or Location, go to PATHS tree (LOCATIONS tree) and: • Select any Path (Location) • Start typing • A yellow window shows up on top with • Press “Enter” 2 1

  40. Network Settings • Checking the settings • Area Management • Modify/Delete/Add Areas • Zone Management • Modify/Delete/Add Zones • Layer Management • Modify/Delete/Add Layers

  41. Preferences [1/7] • Coordinate Settings • To set the coordinates on the GIS to the selected projection, Go to Settings  Preferences • Define display format (DMS or decimal) • Define precision • Define coordinates projection • All settings are set as default for Vodafone Network

  42. Preferences [2/7] • Workarea Settings • Make sure you are using the: • Workarea generated before. • Right Projection, Terrain Layer, Clutter Layer, and ClutterHeight Layer. • Make sure “set as Default” is checked

  43. Preferences [3/7] Plotting Display • Defaults Settings Visibility

  44. Preferences [4/7] Environment Files • MW Settings Mean Time to Repair XPD

  45. Preferences [5/7] • MW Settings • Performance: Important to set before planning This is where you set your availability objectives • Unavailability Allowance: Max. unavailability allowed • Multipath Unavailability: Max allowed multipath unavailability due to external (uncontrolled) factors. • Rain Unavailability • HBR • LBR • Min Availability due to Multipath • Min Availability due to Rain

  46. Preferences [6/7] • Interference This is where you set your interference factors: • Kfactor: Normally set to 1.33 [4/3] • ElevationOffset • Min Interference: beyond that value is no longer used in calculations • Obstruction Loss Algorithm: Rolling Terrain or Knife Edge (more common) • Make sure to check the “UseObstruction” to take Obstruction loss into interference calculation • Max Degradation: Max degradation allowed • Make sure to check the “Max. Deg with Obstruction” to take degradation into Obstruction Loss calculations.

  47. Preferences [7/7] HUBSITE (In case you had Hubsites) Equipment settings

  48. Path Editor • Path Editor • To Calculate Path budget for a particular path, choose the path from the GIS or left tree pane then click “Path Editor” tab.

  49. Link Budget Analysis • Path budget • Click on “Path Budget” and wait for few seconds to generate results. • Performance Calculations • Results are “saved” once generated

  50. Performance Reports [1/6] • Path Budget Report • Summary report of availability objectives due to multipath and precipitation.
