System Performance Engineer

Responsibilities:
  • Network Achievements: Network statistics in my market has always great accessibility, integrity and reliability KPIs within Data and VoLTE networks. I have always win Root Metrics results in my market and never lost to other competitive carriers. Nelson Drive has always showed the best drive test results in my area.
  • Special Events Setup: Provided wireless coverage services for customers attending seasonal events like Rothbury Electric Forest Festival, B93 Bash, and Allegan County Fair which were attended by thirty to fifty thousand people. The process involved initial design, selection of COW location and antenna azimuths, and finally to turn up, test and optimize the temporary network. Customers enjoyed the best network experience during the events with proven statistics.
  • Projects: Rehomed Alltel sites and were integrated into Verizon network. Redesigned network for customers affected by sites that were divested to AT&T from the Alltel merger deal. Used and pushed Standard/Hybrid PRL to customers phones which were affected by the coverage loss. Successfully completed 850 MHz A - B band swap with AT&T in Muskegon. Relocated cell sites due to lease changes and temporary work on the structure. Converted Ground base radio to Remote Radio Head. 4G/3G carriers add were implemented to overcome capacity demand and usage.
  • Network Optimization: Optimized network with traffic distribution among different bands (700 MHz, AWS, PCS and 850 MHz) through different RF and traffic parameters such as A2, A5s, cell reselection priority, load balancing, carrier aggregation, and with power adjustment. This helped offloading exhausted carrier that provided better carrier efficiency and higher throughput with great customer experience.
  • Optimized Network with Traffic distribution among adjacent sites through changes of antenna type, downtilt, azimuth swing, and by power change. The physical optimization improved RSRP, RSRQ and Signal to Noise Ratio and balanced traffic on the cell site within clusters.
  • Hand Over Improvements were performed through parameters changes such as CIO, qOffset, A3 and filter coefficient, and with the propagation RF control.
  • Statistical Analysis were used to check traffic demand in areas with PRB utilization, Data Volume and its correlation with user perceived Throughput; and then optimize traffic distribution to increase network efficiency.
  • Optimization of post network asset addition with grid drive testing, post processing drive data with Windcatcher /Actix tools and implementing changes identified by using the processing tools and statistics.
  • Trouble Shooting Process: Network tool analysis to identify network issues like external or internal Interference, a possible PIM, or antenna hardware problems.
  • Neighbor list tool was for neighbor add/delete and Zite tool for optimization. Used ANR to optimize cell neighbors with blacklisting, overcoming signal overshoot with down tilt, power reduction, and cell range change.
  • New Cell Sites Activation: Choose design criteria for the selection of new cell sites based on customer demand, traffic analysis that would provide best network metric such as RSRP, RSRQ, and SINR and efficient usage of the carriers. Worked with cross functional teams for adding new cell sites into the network.
  • Launched macro and Small cell sites on air that provided coverage enhancement to 4G LTE network in the area, offloaded surrounding sites, and fulfilled customer satisfaction.
  • Activation of TMA, RET, 4wayTx, and 4wayRx for network enhancement.
  • Field Testing: Tested Cell sites with drive testing tool such as Datapro, Dmat, Xcal to identify network problems that helped a quick network resolution or a long term optimization. Identified external interference with noise seen in the field, and then funneled down to the source of interference with Spectrum Analyzer.
  • Coordination with RF Engineering, RF Operations, Network Implementation and Switch Operations to keep flow of daily tasks smoothly on regular basis. Worked with Sales and Marketing group on the new network enhancement plans and resolution of customer’s complaints.
  • Post Processing Software Tools: Used Actix, Windcatcher, Xcal, and Dmat tools to analyze drive test data, and to identify and resolve network problems with RF Engineering changes.
  • Network Engineering Tools: Used Unix based OSS, Zite, True Call, Irisview, Ericson / Nortel Performance tool, Alex, Windcatcher, Actix, Real time tools, Neighbor list tool, Siterra, Remedy for trouble tickets, Site Traker, MARs, Secure CRT, Datapro, CACP, Ericsson and Verizon Statistical tools, Geoplan RF Design tool, Xmap, Delorme and other internal Mapping tool like SPLte and external tool like Google Earth with wireless network information.
