3G NPO Engineer at Nokia

General Purpose:

3G/LTE Radio network planning and optimization engineer is responsible for providing radio detail planning, RAN and eNB parameters planning, pre-launch and post-launch quality assurance and optimization services for 3G/LTE projects in collaboration with related stakeholders.

Main Responsibility Area:

Technologies: 3G/LTE

Vendors: Nokia

• Should have knowledge of LTE Basics, Multi-Layer Idle and Dedicated mode parameters and understand behavior of parameter tuning
• Required to technically deliver network planning and optimization projects according to the agreed scope of work (SoW)
• Performs critical (sometimes escalated) design and performance activities in customer projects independently. These may include complex problem solving in projects with performance requirements and multi-vendor environment
• Good Knowledge of LTE Call flow, Familiarity with Power Control and impact of various power setting on the LTE network
• Identify and resolve Performance degradation in the network within prescribed timelines.
• Perform Counter level analysis and problem isolation to arrive at an early RCA to improve network performance.
• Traffic balancing using physical and soft parameters while ensuring KPI’s are met.
• Good understanding of Nokia BTS hardware: System Modules and RF modules and associated gains and losses of the system, experience on Air-scale products is a big plus.
• Defines the criteria to assess network performance from end-user / service perspective and monitoring of that criteria
• Identifies and anticipates proactively network performance issues (traffic/quality/resiliency) and provides recommendations for improvement
• Optimizes the capacity of the network to meet traffic increase and customer requirements using either network extension or existing network modification
• Ensures that design & optimization guaranty the capability for the network to provide end-user new services in line with customer environment, business goals/drivers and quality
• To communicate effectively and work with a large team in collaborative mode
• Planning the Node-B and eNB sites configuration by using RF planning tool (NetAct Planner/Atoll/Asset) and also defining their related parameters: site coordinates, antenna type, antenna height, antenna tilt, antenna azimuth, CPICH power, cable loss, propagation model parameters
• Setting the specific RF parameters for the site to be integrated.
• Analyze site performance after integration through drive test measurements and/or OSS measurements, detecting eventual problems and recommending changes to fixing problem
• Defining and monitoring parameter consistency check rules to Maintain RAN /eNB parameter database consistency
• Defining and monitoring KPIs reports on network, area and RNC level
• Defining and optimizing “worst objects” reports at eNB, Node-B and RNC level, as well as troubleshoot and recommending the software changes, hardware changes or alerting O&M in case of hardware problem
•  Nokia 3G/LTE parameters detailed knowledge and optimization
• Giving inputs in terms of capacity, quality and coverage for expansion phases
• Implementing new features required to improve overall radio network performance
