Today’s buildings, with their thick walls and energy-efficient windows, can hinder RF (radio frequency) signals. To help keep your radio communications interrupted, Motorola Solutions provides complete DAS/BDA solutions, including equipment, expert design, installation, and ongoing maintenance.

The first step in building a robust DAS/BDA system is a thorough RF site survey. This survey helps us understand RF signal propagation and the environment, enabling us to develop a cost-effective and technically sound solution.

Our proven methodology includes:

  1. Obtaining floor plans.
  2. We conduct a grid walk of the building to assess signal coverage, pinpointing dead zones with empirical data rather than relying on anecdotal information.
  3. Pinpointing optimal locations for BDA, cable/fiber runs, and antennas.

Our engineering team will create a preliminary design based on this data. Motorola Solutions field technicians will then measure essential RF signal parameters on-site.

The survey aims to assess:

  • Off-air signal readings and donor antenna sites.
  • RF signal propagation characteristics based on building structure (e.g., concrete, steel, LEED windows).
  • Suitable installation locations for equipment and antennas.
  • Cable routing options, including any drilling or structural considerations.
  • Local code compliance.

After the survey, our team analyzes the findings to generate a detailed report, outlining signal strengths, coverage areas, potential interference, and architectural impacts on wireless propagation. Utilizing advanced RF coverage analysis software, we can visualize signal behavior for both pre- and post-DAS installation comparisons.

This tailored approach ensures optimal performance and the most economical DAS/BDA solution for your needs.
