WORK HISTORY
Rf Design Engineer @TELUS
Toronto, ON, CA
Analyze existing coverage with industry standard tools to identify the needed coverage enhancements (design changes or new cell sites). Select, calibrate (with field data) and validate the propagation models with industry standard tools.Deliver RF design by selecting the best feasible site candidate/location, antenna attributes (location, height, model, azimuth, tilt), technology compatibility strategy and multi technology antenna strategies.Calculate link budget and system noise figure. Justify the design with calibrated propagation studies and with technology specific network simulations using industry standard tools.Deliver the RF data fill design including handover parameters/strategies and cell attributes.Understand the specific technologies worked on (iDEN, CDMA, EvDO, UTRAN, etc.) and the impacton the design.Perform the initial optimization after coverage enhancements (design changes or new cell sites) by adjusting if needed the tilt, azimuth, data fill parameters.Cluster and network prime of Huawei to Samsung swap.(Checking pre and after swap KPI and coverage)
