Experienced in Ericsson integration and drive testing of 4G/5G Macro and multi-carrier small cells and in-building BBUs, including CBRS and now CBAND. Obtained CBRS CPI Professional Engineer Certification. Perform CBRS registration provisioning on SAS servers. End to end CBRS integrations. Highly experienced in end-to-end Ericsson 5G MM wave small cell integration and verification. This included off-line pre-integration programming, performance testing and 4G anchoring. Also performed call tests for 5G UWB and remote scripting support.Perform integrations of Ericsson Grand Master (EGM) clocks for 5G SC PTP timing, 7750 IXR expansion units, migration procedures from older a BBU architecture to new equipment with enhanced features. Integrate and provision 7705 SARs for Backhaul of BBUs. Proactively manage a large cell orbit and responsible for all cell site maintenance, and KPIs affecting end users. Debug telecom, power, HVAC and fiber/microwave transmission issues as they arise and resolve them or dispatch vendors to address issues. Install and define alarming via SiteBoss, Ericsson SAU, NOK 7705, and Lucent ECP. Utilize test equipment to debug PIM/VSWR and spectrum analyzers for interference testing. Also use VIAVI/JDSU TBERD 5800 equipment to perform distance to fault fiber tests and, fiber acceptance and to verify 5G IP addresses.

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 solutions for Alcatel and Nokia Airscale eNodeB technologies in end-to-end system test labs to create coaxial and OTA paths that control RF levels to test locations, test equipment, and UE load generators. • 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 architecture for test environment, submitted budget requests, negotiated with vendors, ordered hardware and pushed project to meet extremely aggressive testing dates. • 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 hardware and providing more system availability to testers.• 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.

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 other team members. Maintained and continuously evolved equipment for testing needs and provided debugging support to software testers as well as providing customized RF solutions for test team’s unique needs.• 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 eventually over 400 VzW/ATT/Sprint with over 1500 RRHs. • 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 microwave backhaul link. Coordinated with architects and external contractors for installations rental agreements. • 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 previous systems, reducing space 75%, with 4 times capacity.• 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. • Volunteered to manage test equipment calibration and ESD for 2 years on top of engineering work ensuring continuation of ISO9000 certification.
