EXPERIENCE

Senior RF/RAN Engineer (Nokia-Cisco-Ericsson)

AT&T Mobility – Atlanta, GA Jan2017-July2020

RAN Transport engineer working on Nokia and CISCO SIAD and MSN’s. Activities include 5G SIAD migrations, MSN rebalance, Node B re-homes, EVC up speeds, bandwidth and net quality testing, electrical to optical port conversions. On the RAN side, preform Pre-post activities and performance monitoring of UMTS, LTE, 5G sites for Ericsson, Nokia and Siemens nodes involved in the transport cut (lock/unlock, pre-post KPI’s, alarm clearing, parameter checks).

Mobility integration engineer for AT&T National Translations Center. Create scripts using CIQ for several complicated Ericsson LTE and 5G NR configurations such as cabinet and radio adds, XMU/Sectorization, 2x2 and 4x4 MIMO. As well as any provisioning projects like Small Cell, C-RAN (Centralized RAN) and 5G remote radios 6630.

Wireless translations engineer. Implement the latest RF parameters and Gold Standards as well as field guide alerts for LTE and 5G Ericsson elements. Some examples include Dynamic UE Admission Control, Cat-M1 & NB-IOT activation, Carrier Aggregation, Inter-frequency load balancing, 5G PCI/RSI Optimization

RF Engineer III

AT&T Mobility – Atlanta, GA Aug 2005-Jan 2017

Area engineer responsible for the launch of new LTE sites as well as 2nd, 3rd and 4th carrier. Drive test and analyze performance of LTE sites, DAS and microcells. My responsibilities include working with different teams and groups from ATT design and implementation, to field support teams and Operations.

Responsible for the post-launch performance of the new carriers by monitoring LTE and Volte, accessibility, retainability, Throughput, data volume and handover performance.

Review the power settings, tilts, handoff performance, SRVCC, overshooting and PCI conflicts.

Ensure the sites are alarm free, the features are aligned, and parameters are set according to Gold Standards.

RF tools Support Engineer

Optimi – Indianapolis, IN June 2004-Aug 2005

RAN support engineer for RF tools and software developed by Optimi. These tools are used for frequency and PCI planning, layer management, azimuth, tilt and power optimization as well as self-optimized network. ACP, AFP and Cell Design Tool.

Provided day to day support for wireless carriers with using the tools as well as customizing the software to best support the specific need in the market (capacity, coverage, Throughput).

Wireless Systems Engineer

Ericsson Inc – Dallas, TX. Sept 2000-May 2004

RF technical lead for the AWS rollout in several US markets. Review design survey packages in order to determine the best site configuration (antenna type, height, azimuth, tilt). Create RF design sheets, CIQ’s and plumbing diagrams for the new co-located macro and micro sites. Provide coverage analysis and frequency plan using Tems Cell Planner. Create CDD (cell design data) and generate DT using the PARAGEN tool. Generate documentation for the final design acceptance (MAPINFO and TCP coverage & C/I plots, equipment list, TMA & TRU count, PCN analysis).

Technical lead for 1900 GSM market launches in the Midwest. Drive test analysis, parameter optimization and monitoring of statistics in order to bring the newly launched clusters to GREEN.
