PROFESSIONAL EXPERIENCE
AUGUST 2005 - PRESENT: Sprint Nextel Corporation, Assistant RF Engineer National RF Engineering Headquarters, Overland Park, KS-66251 Motorola Parameter Testing and Optimization Intense study and research of call-processing parameters in 1x-RTT and EvDO. Design of test plans to optimize parameter settings for 1x-RTT and EvDO networks for Motorola. Co-ordination for implementation of parameter changes according to test plans. Trending and analysis of various KPIs and pegs related to the ongoing tests. Detailed analysis (pre-post) of the data trended to study the effect of the parameter change and its impact on the network. Decision-making of the best iteration value for the parameter under research. Support for the field markets to implement / rollout the recommended changes. Technical support to the field markets for any parameter related issues.
Tests Accomplished CASHO (1x-RTT): Improvement in setup failures by 12% 9112 Handoff Enhancement (1xRTT): Improvement in drops by 2% Signaling Link Protocol Enhancement (EvDO): Improvement in drops by 5% Dormancy Timer (EvDO): Improvement in drops by 50% Transitional Probability (EvDO): Improvement in Reverse link throughput by 15% Dynamic RC3/RC4 Algorithm: Relieve Walsh Code Blocks nationwide. Paging Enhancement Test: Improve Paging Success Rate by 0.5%.
Parameter Management and Release Management Release Management Process Liaison between the vendor and team, responsible for the sign-off of every new release after completion of FIT testing. Provide inputs towards Tool Development for EvDO performance monitoring. Maintaining Golden Image for parameter compliancy nationwide.
SPRING 2004 SUMMER 2005: Applied Electromagnetics Laboratory, Department of Electrical and Computer Engineering, University of Houston, TX, USA. § RF Engineer worked on the calculation of Periodic Greens Function for Layered Media using Ewald Method.
