This case study illustrates how financial benefits are achieved by in depth analysis and review of the current conditions rather than employ a DAS (Distributed Antenna System) installer to quote on a replacement DAS that is not necessary.

Here’s a breakdown of how this was achieved

  1. Initial Problem Identification: Tenants in a major Melbourne facility were experiencing poor mobile coverage on certain floors, leading to dissatisfaction with the DAS performance. The building owners were considering proposals to replace the entire DAS, which was estimated to cost between one and two million dollars.
  2. Engagement of siteXcell for Investigation: siteXcell was brought in to investigate and analyse the issue. This decision to seek a specialised and independent investigation before proceeding with a costly overhaul was the crucial first step in the Client’s cost-saving strategy.
  3. Thorough Analysis and Investigation: siteXcell conducted a detailed investigation, which included both a visual inspection (using the construction drawings) and signal testing on the floors where coverage issues were reported. This comprehensive approach ensured that the problem was accurately identified and isolated to just a few floors, indicating a past potential fitout issue.
  4. Discovery of the Actual Issue: The investigation revealed that the problem was not with the DAS itself, but rather with the positioning of several antennas. It was found that these antennas had been inadvertently pushed above the ceiling, which significantly degraded their signal quality and performance.
  5. Cost-Effective Solution: By simply lowering the identified antennas back to their correct positions below the ceiling surface, siteXcell was able to provide the solution to restoring adequate signal strength and coverage. This solution was not only effective but also minimally invasive and significantly less expensive than replacing the entire DAS.
  6. Result: The adjustment of the antennas led to improved signal coverage, thereby resolving the tenants’ complaints. This solution eliminated the need for a massive and disruptive construction project, saving the building owners a substantial amount of money (between one and two million dollars) and avoiding an unnecessary replacement of the DAS.
  7. Client Satisfaction: The tenants were satisfied with the restored coverage, and the building owners were relieved to have resolved the issue without incurring a major expense. Problem solved!

This case exemplifies the importance of accurate problem diagnosis and considering simpler, more cost-effective solutions before committing to large-scale and expensive DAS projects. Through our efforts we saved the Owners between $1-2million that was proposed for a new DAS through our mitigation analysis and actions.
