Job description
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.
Job Grade 8
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
