  1. The Leader in Industrial Data Communication Solutions Training: Wireless Site Surveys PN: 154-10002-001 Video PN: 158-10002-001

  2. Section:Introduction

  3. Data-Linc Group • Industrial grade products include: • Wireless Modems • Ethernet Radio Modems • Serial Radio Modems • Copper Wire Modems • Dial-up/Leased Line • Dedicated Wire FSK Modems • Specialty: • Analog/Discrete Multiplexers • 4-Port Switch • Accessory Devices • Factory pre-configured for your application Site Surveys

  4. Benefits of RF Site Survey • Engineered solution, by design • Reduce project cost overruns and rework • Minimize startup surprises and project “creep” • Maximize communication effectiveness • Minimize communication faults • Consistent response times • Reliable operation over project lifecycle

  5. Who Performs the Survey? • The Customer, the Distributor • Contracted third party • System Integrator • Engineering Firms (Titus Engineering) • Local wireless businesses • Wireless service and/or repair • Some electrical shops • Radio tower sellers • Data-Linc - $800/day plus expenses • Skills required: • Understand Line Of Sight (LOS) requirements • Ability to configure and install Data-Linc radio systems and correct possible abnormal operation • May require work at heights

  6. Site Survey: When? • Alternatives Analysis & Preliminary Design • Theoretical Survey • Physical Survey • Detailed Design • Generate a Bill Of Materials • Project Startup • Sustaining • Conduct Site Surveys in early stages of project

  7. Types of RF Surveys • Demo Only • Theoretical • Physical

  8. Example Survey Result • Station Colors • Yellow – Master • Blue – Existing • Green – Phase 1 • Red – Phase 2

  9. Section:RF Survey Types

  10. Survey Type: Demo Only • Data-Linc/Distributor provide demo equipment • Conducted in the field • Rapid equipment setup and test • For: • Small, straight forward projects • Indoor or short range outdoor projects with significant LOS interference • Examples: • RF path is from building to building through interior and exterior walls • Moving equipment around obstacles in the warehouse • A mile through trees

  11. Survey Type: Theoretical • Theoretical – Mostly performed in the office • For most outdoor, multiple station projects • Requires prior collection of site coordinates • Only as accurate as maps and coordinates provided • No visibility of trees, vegetation, buildings and other such RF obstacles • Can be performed • Manually: using maps, compass, pen and paper • Semi-automatically: using RF computer programs

  12. Survey Type: Physical • Physical – Always performed in the field • Demo only survey is a quick physical survey • For almost all projects and typically uses demo equipment • Must have a repeatable plan for study of each site to • Collect radio performance data • Prove the theoretical study by confirming RF quality • Possible Requirements: • Radios, coax and antennas to build a test network • Temporary installation of “fixed” equipment • A vehicle to be a radio site on wheels • Radio equipment, laptop, GPS and power • A means of achieving expected antenna heights

  13. Survey Steps • Step 1 – Preliminary Data Collection • Step 2 – RF Network Design • Step 3 – Theoretical Survey • Step 4 – Physical Survey • Step 5 – Complete Summary Report

  14. Section:RF Survey Steps

  15. Step 1 - Collect Information • Project scope and Implementation Plans • Identify Key contacts • Potential Competition • Cost targets • Timelines

  16. Step 1 - Collect Information (1) • Obtain Topographic Maps • Identify all sites - existing and future • Station Name • Station Purpose • GPS Coordinates with altitude • Identify possible repeater sites • Identify potential RF noise sources • Identify inter-site process relationships

  17. Step 2 -RF Network Design • Determine RF band • Determine level of redundancy • Develop Network Architecture • Keep inter-site processes on the same radio network • Estimate system response times • Estimate data throughput requirements • Estimate amount of data • Estimate data update rates • Partition network as required to • Improve response times • Reduce failure vulnerabilities

  18. Step 2 - RF Network Example

  20. Step 3 - Theoretical Survey • Using maps and station location data • For each wireless network • Plot all locations • Plot desired RF links • Resolve LOS issues or weak RF links by • Adjusting antenna types and height, or • Convert slaves to repeater slaves, or • Find new repeater sites • Repeat above steps till satisfied • Create Reports • Cross-sectional Drawings • Calculate RF quality for each path • Make recomendations

  21. Step 3 - Map Example

  22. Step 3 – Cross-section Example

  23. Step 4 - Physical Survey • Decide on test plan • Apply plan consistently • Determine testing technique • Radio loopback • Use User Equipment • Method to record test results • Install fixed equipment • Prepare mobile remote • Prepare report • Record results and observations • Make recommendations
