Manual testing of the passive RF components of an In-Building (DAS) antenna system can be a lengthy and expensive process, particularly if retesting becomes necessary. The manual testing process used for tower work does not scale well for the much more complex DAS installations. Automation of the field RF testing process can dramatically reduce common testing errors, cut testing time up to 90%, virtually eliminate mislabeled traces, and greatly reduce rework and the resulting engineering involvement. In addition to eliminating common causes of testing errors, cloud based automated testing tools can provide immediate visibility of results, work tracking, and simplified reporting.
