DAS commissioning, testing, and optimization

DAS Commissioning Process

DAS commissioning is a systematic process to verify that the installed system meets design specifications before handover to the operator. The process begins with visual inspection of all components, cable routing, connector torque verification, and labeling accuracy. Next, swept frequency testing measures insertion loss and return loss across all operational bands at every antenna port using a network analyzer. Each measured loss is compared against the design power budget with a tolerance of plus or minus one point five dB. Any port exceeding tolerance requires investigation — typically a…
