Propagation model calibration for 3G using 2G existing live data.
3G cell plan plots generation within Max Path loss, CPICH cover Pilot Ec/I0 dominance and quality analysis, Best server plots per bearer/service (UL and DL), ho maps and solving Pilot Pollution.
Generation of 3G traffic maps by extrapolating traffic density maps from 2G Live
Dimensioning the RAN network (number of channel elements, Node-Bs, RNCs) according to the coverage, capacity and quality requirements.
Setting the specific RF parameters for the site to be integrated: RNCid, WBTSid, LcrId, MCC, MNC, LAC, RAC, SAC, CId, UARFCN frequency, scrambling code, T cell, neighbours.
Planning Node-Bs in a WCDMA RF planning tool (like NetAct Planner) defining their related parameters: site coordinates, antenna type, antenna height, antenna tilt, antenna azimuth, CPICH power, cable loss, propagation model parameters.
New Ercisson Feature Trials Like TCC, Double BA List, Reduced Power Consumption, TMA implementation, Assignment to Other cell (Directed Retry)
Proposed and successfully implemented traffic balancing solutions using site re-design and parameter reconfiguration (DHA and DYMA).
Coordination with the Operations and Maintenance, Customer Care on network performance to identify regional optimization issues for improvement of KPIs.
Design of BSC parenting plan catering network dimension of 14 BSCs.
Re-Design of LAC parenting plan splitting the boundaries based upon key geographical locations in Major cities.
Proposed cost effective solutions of site sharing with other competitors utilizing the existing infrastructure.

Achieved Yearly Targets of Network KPIS as set by higher management
GPRS & EDGE optimization
Will add later
n charge of designing cell sites in Salem area and conducting drive tests to minimize drop call rates. Designed and reconfigured 40 T Mobile cell sites reducing coverage gaps and drop call rate to 60%. Used solid RF Engineering principles and planning tools to maximize coverage, capacity, and performance of GSM radio network. Worked with other engineers to address discovered issues. Key accomplishments:
Engineering design and system performance of 3G- GSM (GPRS/ EDGE) Radio Network.
Included the release of 50 search area maps, site visits to study the feasibility of proposed candidates, pre- construction drive test analysis, predictive model optimization, review of planning drawings, frequency planning, capacity planning, initial cell site data.
Regulatory and FAA issue resolving, attending zoning hearings, review of construction drawings, monitor construction phases, analyze antenna tests, and perform site audits. Participated with federal, state and local jurisdictions to insure regulatory such as 911, FAA and zoning compliance.
Provided engineering support to sales and customers. Evaluated capacity
