Field Testing / Site Survey
A Rigorous Site Inspection & Coverage Testing Protocol
The Purpose of Comprehensive Site Inspections and Coverage Testing Conducting a thorough site inspection and coverage testing is pivotal for ensuring complete adherence to cellular coverage regulations within commercial buildings. This vital procedure serves dual functions: it identifies the need for a Distributed Antenna System (DAS) to bolster coverage, and it establishes a performance benchmark pre- and post-DAS installation. At Total Telecom Corp, DAS site surveys are an integral part of our protocol, laying the groundwork for the design phase of in-building Distributed Antenna Systems (DAS).
Site Inspection and Coverage Testing Procedures Total Telecom Corp’s team of Radio Frequency (RF) and DAS specialists perform detailed site inspections and coverage tests. These evaluations meticulously identify and document key factors such as weak signal levels and interference sources. Armed with a comprehensive dataset and external network quality-of-service measurements, our experts produce an extensive analysis and recommendation report, which also highlights potential optimization areas through DAS implementation.
Why Total Telecom Corp’s DAS Field Testing is Essential A detailed site review coupled with coverage testing is crucial to ensure that commercial buildings meet the necessary internal Emergency Responder and Carrier coverage standards. This process determines the need for a Bi-Directional Amplifier (BDA) or DAS to enhance mission-critical coverage and sets a benchmark for performance comparison pre- and post-DAS installation. At Total Telecom Corp, DAS site assessments are a standard practice prior to developing in-building Distributed Antenna Systems, guaranteeing regulatory compliance and peak coverage efficiency.
Site Inspection Procedures Our seasoned RF and DAS professionals conduct comprehensive on-site evaluations, focusing on RF signal characteristics and local regulatory requirements:
- Propagation Analysis: Examining variables affecting signal propagation.
- Frequency Spectrum Assessments: Conducting thorough evaluations of the frequency spectrum.
- Prioritization: Identifying and ranking areas requiring immediate attention.
- Signal Source Investigation: Surveying signal origins such as radio and cellular towers.
- RF Readings: Recording raw RF data, encompassing baseline RF noise levels and donor signal strength.
- Obstacle Review: Assessing impediments to RF signals, including natural terrain and man-made structures.
- Compliance Assurance: Ensuring conformity with fire safety standards, building codes for Emergency Responder Communication Enhancement Systems (ERCES), and FCC regulations.
- Licensing Verification: Determining FCC license holder(s) pertinent to P25 public safety radio network broadcast agreements.
- Approval Acquisition: Securing an approval letter from the Authority Having Jurisdiction (AHJ) upon meeting internal site signal coverage standards and code compliance.
