LINKPlanner Concepts

NLoS and LoS

         The Cambium Networks Series of point-to-point wireless Ethernet bridges are
         designed to operate in non-line-of-sight (NLoS) and line-of-sight (LoS)
         environments. Link planning and estimation enable a link of known quality to be
         installed. PTP LINKPlanner uses path profile data to predict the data rates and
         reliability over each link, through adjustment of antenna height and RF power.
         When the link is installed, the mean path loss can be checked to confirm these
         predictions.

Architecture

         The PTP LINKPlanner is an application that runs on Windows or Macintosh. It
         performs the calculations from the ITU recommendations ITU-R P.526-10 and ITU-R
         P.530-12 to predict NLoS and LoS paths for anywhere in the world. Path profile
         data can be obtained in a number of different ways depending upon global
         location. Cambium provides a method for obtaining path profile data; see Path
         Profiles. Trees and buildings (obstructions) can modify this profile, and often the
         path must be surveyed to establish the correct estimation.
         The main concepts of PTP LINKPlanner are:
               ˆ Project: a set of data about the sites and links in a wireless network.
               ˆ Site: the location of a PTP outdoor unit and its antenna.
               ˆ Link: a wireless connection between two sites.
               ˆ Path: an alternative wireless link between two units at different sites, when
                 each site has multiple units.

Inputs and Outputs

         The main inputs to LINKPlanner are:
               ˆ Site name, position and maximum antenna height (input by the user).
               ˆ Details of the PTP equipment and license restrictions (selected by the user).
               ˆ Required performance targets for each link (input by the user).
               ˆ Profile of the terrain along the path of each link (obtained using a Cambium
                 tool).
               ˆ Details of any obstructions or reflections that may affect the performance of
                 a link (obtained from maps, survey data and Google Earth(TM)).
         The main output from LINKPlanner is a performance summary that shows how well
         the link is predicted to perform in response to the selected combination of inputs.
         It shows predicted and required throughput performance and availability at each
         end of the link.

CHAPTER 3




                                    Using PTP LINKPlanner



The goal of link planning is to ensure that each direction of the link will perform to
an acceptable level, measured by the Throughput and Availability values in the
Performance Summary section of the Link Page. To allow PTP LINKPlanner to
predict Throughput and Availability, the planner must enter the variables that
affect link performance, such as: band, region, equipment, antenna, height,
terrain, obstructions and reflection.
To achieve this goal, follow this process:
  1. Start the application and set options. See Starting the Application.
  2. Build a project to model a PTP link (or network). See Projects.
  3. Enter details of all sites in the project. See Sites.
  4. Define the links between sites, create profiles of those links and update the
     profiles with details of obstructions. See Links.
  5. Adjust the link profile to allow for terrain height variance, obstructions and
     reflection. See Adjusting Link Profiles.
  6. Confirm that the link will perform to an acceptable level, measured by the
     Throughput and Availability values in the Performance Summary section of
     the Link Page.
  7. Export and report project, site and link data. See Exporting and Reporting
  8. If TDD Synchronization is required, see Setting TDD Synchronization
  9. If Hot Standby Protection or Spatial Diversity is required, see Setting Hot
     Standby Protection (1+1)
10. If 2+0 Antenna Sharing is required, see Setting 2+0 Antenna Sharing
11. If ODUs are to be mounted indoors or at the base of the tower, see Long
    Waveguide

Importing Path Data

         If path data is available in Hydra, PTP, csv or Pathloss files, it can be imported and
         used to populate a project with sites, links and profiles.
         Before importing path data, create the project and enter defaults. Path data can
         then be imported from Hydra, PTP, csv or Pathloss.

Sites

             Sites are points that must be connected via PTP links. A Project would normally
             contain at least two sites.
             Identify all sites in the project and obtain their latitude and longitude using the
             WGS84 frame of reference. Use tools such as:
                  ˆ GPS during a site survey.
                  ˆ Google Earth(TM): http://earth.google.com. This application must be
                    downloaded and installed.
                  ˆ Multimap: http://www.multimap.com/.



                    When potential Sites have been identified and entered in LINKPlanner,
                    the link profiles between those potential sites can be previewed in
                    Google Earth(TM) to see which links are definitely line of sight (and
                    therefore worth pursuing), or VERY non-line of sight (in which case they
                    may not be worth pursuing). See “Previewing Link Profiles” in Using
                    Google Earth(TM).

New Sites

             Import sites from external files as described in Copying or Importing Sites, or
             create them in PTP LINKPlanner as described in Creating Sites. It is also possible
             to create new sites and links by importing link data as described in Importing
             Links from a Spreadsheet.

Sites List

             Display the list of sites in the project, as described in Displaying the Sites List.

Viewing and Updating Sites

             When sites have been created, open them in the following ways:
                  ˆ Single-click the site node in the Navigation tree.
                  ˆ Double-click on the site in the Sites list.
             The Site page is displayed. See Site Page.

Copying or Importing Sites

             Site data can be brought into PTP LINKPlanner from Google Earth(TM) (.KML) or
             from comma-separated files (.CSV). Before copying or importing sites, ensure that
             the correct project is open in PTP LINKPlanner.

  • 20. PTP LINKPlanner User Guide, Release 3.3.3 LINKPlanner Concepts NLoS and LoS The Cambium Networks Series of point-to-point wireless Ethernet bridges are designed to operate in non-line-of-sight (NLoS) and line-of-sight (LoS) environments. Link planning and estimation enable a link of known quality to be installed. PTP LINKPlanner uses path profile data to predict the data rates and reliability over each link, through adjustment of antenna height and RF power. When the link is installed, the mean path loss can be checked to confirm these predictions. Architecture The PTP LINKPlanner is an application that runs on Windows or Macintosh. It performs the calculations from the ITU recommendations ITU-R P.526-10 and ITU-R P.530-12 to predict NLoS and LoS paths for anywhere in the world. Path profile data can be obtained in a number of different ways depending upon global location. Cambium provides a method for obtaining path profile data; see Path Profiles. Trees and buildings (obstructions) can modify this profile, and often the path must be surveyed to establish the correct estimation. The main concepts of PTP LINKPlanner are: ˆ Project: a set of data about the sites and links in a wireless network. ˆ Site: the location of a PTP outdoor unit and its antenna. ˆ Link: a wireless connection between two sites. ˆ Path: an alternative wireless link between two units at different sites, when each site has multiple units. Inputs and Outputs The main inputs to LINKPlanner are: ˆ Site name, position and maximum antenna height (input by the user). ˆ Details of the PTP equipment and license restrictions (selected by the user). ˆ Required performance targets for each link (input by the user). ˆ Profile of the terrain along the path of each link (obtained using a Cambium tool). ˆ Details of any obstructions or reflections that may affect the performance of a link (obtained from maps, survey data and Google Earth(TM)). The main output from LINKPlanner is a performance summary that shows how well the link is predicted to perform in response to the selected combination of inputs. It shows predicted and required throughput performance and availability at each end of the link. 12 Chapter 2. Getting started

  • 43. CHAPTER 3 Using PTP LINKPlanner The goal of link planning is to ensure that each direction of the link will perform to an acceptable level, measured by the Throughput and Availability values in the Performance Summary section of the Link Page. To allow PTP LINKPlanner to predict Throughput and Availability, the planner must enter the variables that affect link performance, such as: band, region, equipment, antenna, height, terrain, obstructions and reflection. To achieve this goal, follow this process: 1. Start the application and set options. See Starting the Application. 2. Build a project to model a PTP link (or network). See Projects. 3. Enter details of all sites in the project. See Sites. 4. Define the links between sites, create profiles of those links and update the profiles with details of obstructions. See Links. 5. Adjust the link profile to allow for terrain height variance, obstructions and reflection. See Adjusting Link Profiles. 6. Confirm that the link will perform to an acceptable level, measured by the Throughput and Availability values in the Performance Summary section of the Link Page. 7. Export and report project, site and link data. See Exporting and Reporting 8. If TDD Synchronization is required, see Setting TDD Synchronization 9.
