Initial Site Surveys and Final Site Audits
We perform detailed technical site surveys and audits for site inventory, circuit configurations, quality compliance and safety issues. We ensure that the quality is sufficient for all future operations that cover from site assessment to site installation.

Below is a list of microwave survey and audit services we provide:
  • RF-equipment and site inventory surveys
  • Foundation, structure and quality surveys
  • Tower climbing and roof-top surveys
  • Antenna specifications (long-lat, orientation, height) conformance service
  • Health and safety audits
  • Damage assessments
  • RF compliance, interference and evaluation services
  • Power and wiring requirements, access points, floor plan generation service
  • Engineering documentation service and in-depth site audits
  • Comprehensive site closeout packages
Installation and Commissioning
