About The Position

Senior Engineers, Radio Frequency located in Livonia, MI will provide radio frequency (RF) and/or wireless transmission equipment requirement support; responsible for end-to-end design, deployment and optimization of Next generation networks (macro, small cells). Position duties and responsibilities include, but are not limited to: • Perform multi band LTE Optimization & Design of LTE 2500, L1900, L2100, and L800 of Macros and Small Cell sites. • Perform small cells design for coverage and capacity enhancements and identified new hub location. Responsible for end-to-end RF design and deployment, of T-Mobile 3G, 4G and 5G network. • Perform coverage parity analysis of different 4G, 5G bands, run predictions, and create delta maps. • Support monthly POR governance (Site prioritization and RFDS). • Run predictions using performed pops analysis, performed POR objective analysis and enhance 5G coverage based on analysis. • Perform Opex and Capex analysis for sites with deployment team and provide conclusion based on coverage, users, costing and morphology. • Parameter tuning (LTE idle and connected mode parameters) and coverage analysis is done to improve the overall performance of the network. • Troubleshoot areas of customer issues and propose solutions for improvement; perform multi-band load balancing to optimize traffic among LTE carriers and multi-technology load balancing to optimize traffic among technology layer. • Perform drive testing using Xcal and Tems and analysis of Layer 3 Protocols of drive test log for different technologies such as LTE & 5G. • Monitor performance indicators for CS and PS domains services in terms of accessibility, retainability, call completion success rate, integrity, mobility, system utilization and availability for Ericsson, Samsung and Nokia OEM’s. • Troubleshoot typical problems like interference, handoff failure, low throughput/ poor SINR.

Requirements
