These types of problems that show up during the commissioning stage can frustrate any PM or installer on a tight deadline: *Coax infrastructure — swapped cable *Antennas — faulty equipment *SFP selection and performance — incorrect or improper SFPs *Equipment performance — radio defects, bad line cards, incorrect provisioning, wrong software versions *RF environment — external interferers, uplink noise issues *PIM — external or internal sources CellAdvisor and T-BERD with BBU Emulation can find the causes of those problems in advance by allowing: • CPRI Layer 2 RRH initialization • SFP identification • RRH configuration • Antenna tilt (RET) and VSWR • PIM testing • Interference identification • Digital DAS coverage and signal quality testing • RRH performance verification • Over-the-air LTE verification (CellAdvisor only)
