Lead the outdoor (field) test activities for Parallel Wireless's wireless telecom and cloud-based 4G/5G ORAN solutions, owning the outdoor test domain end-to-end from strategy to KPI analysis.
Responsibilities
Lead and own the outdoor/field test activities of the team: plan, schedule and execute drive tests, walk tests and field trials of Parallel Wireless 4G/5G ORAN products (radio units, DU/CU and core).
Define the outdoor test strategy, test plans, test cases and acceptance criteria covering coverage, capacity, throughput, latency, mobility (handover/cell reselection), interference and KPI benchmarking against 3GPP and customer requirements.
Design and build outdoor end-to-end test setups: site survey and selection, antenna and RF path, backhaul, power, GPS/timing, UE fleet and measurement tools.
Execute field measurement campaigns with drive-test tools and scanners, and analyze RF and performance KPIs (RSRP, RSRQ, SINR, throughput, BLER, latency, call/session drops, handover success rate).
Analyze and debug UE, RAN and core logs collected in the field and resolve issues in outdoor setups (For Ex: UE/mobile issues, RF/antenna/fiber connectivity, backhaul, power and timing, etc.); isolate RF, baseband, configuration and software issues and drive them to root cause together with R&D.
Requirements
Bachelor degree in Electrical, Electronic Communications/Computer Science Engineering
