Using geomatics and drones to assess line of sight (LoS) and radio clutter/ interference

A customer was using helicopter-based LiDAR to assess radio and transmission performance and interference from clutter. The customer was looking for an alternative solution that could be more flexible and more cost-effective.

Objectives

  • Assess radio coverage for interference from nearby clutter.
  • Assess transmission path profiles and interference from clutter.
  • Identify any features interfering with performance.

Solution

Digital Asset Solutions introduced a two stage process where existing LiDAR mapping data (Digital Terrain Modelling and Digital Surface Modelling) was used to assess radio and transmission performance at a much lower cost than new LiDAR capture. In cases where the LiDAR mapping data did not provide the necessary assurance, a second stage process consisting of a UAV survey was completed to further investigate and identify potential issues.

DAS then issued a full report consisting of radio/path details, mapping, path profile (LoS) including terrain, clutter, fresnel zones and K factor and a summary identifying any features causing interference/obstruction with a proposal for resolution.

Benefits

  • A much more flexible and cost-effective solution.
  • Ability to identify radio or transmission infringements.
  • Point-to-point LoS confirmation over distances up to 40km.
  • Option to identify land ownership and advise on and/or conduct potential remedial works.
  • Option to digitally twin A End and B End to support link/infrastructure design.
