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:
- 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 Huawei BTS hardware
- 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 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
- Huawei 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
