• Meticulously designed, engineered and integrated 4G LTE RAN system test labs for fALU Macro, Mini and Microcells, as well as NOKIA Airscale BBUs, small cells and associated RRHs. Innovatively developed RF engineering.
• Lead project engineer to integrate first Sprint 4G mMIMO test environment at campus. Proactively shifted work schedule to overlap with Chinese time zones to procure technical requirements. Designed and proposed RAN.
• Evolved 4G Sprint mMIMO test environment to split 4G/5G and 5G standalone configs and provided evolution flexibility into original 4G design, providing 5G environment solutions ahead of schedule.
• Designed flexible system to simultaneously test both VzW and ATT configs with both ALU and NOK eNodeBs as lead project engineer for DRFM equipment with Commscope ION DAS test environment, saving project $120K in.
• Designed UELG (user equipment load generator) mobile infrastructure to allow commercial mobiles to be part of call model, critical requirement for customers and became template for larger systems.

Naperville. IL

• Engineered and integrated RAN HW for Vzw, ATT and Sprint 4G LTE and 5G end-to-end system test lab. Collaborated with test teams, analyzed feature documents, created detailed engineering documents for installers and.
• Lead engineer to integrate RAN HW for first VzW 4G LTE end-to-end system test lab. Coordinated with real estate and facilities teams to provide AC/DC power, cooling, and infrastructure. This grew from 2 VzW eNodeBs to.
• Solved outage with LTE test program by installation of LTE eNodeBs to rooftop antennas on 2 ALU buildings and local hotel for OTA drive-path testing. Conferred with FCC for LTE 700 MHz licenses and point to point.
• Collaborated with Quintech, Inc. to develop combination RF switch matrix and RF attenuation system to accurately attenuate signals to various mobile/UE test stations, simulators and emulators, reducing costs 40% of.
• Improved tester setup times 50% and reduced expenses over $500K by designing and integrating scalable RF coaxial patching system that allowed over 1500 radio heads to be patchable to 20 separate Prisma UE emulators.
• Created in-house solution at 62% less and saving $150K by designing and testing OTA RF shielded boxes that allowed true OTA connectivity to commercial UE/mobile devices in user areas.
