September 2007 –
Assistant Professor
Dec. 2006-September 2007
Radio Frequency Design Consultant
Cricket Communications
Worked on CDMA cellular system design
of
Propagation Environment Characterization and CW Testing:
Includes detailed study of clutter and
terrain of the designated areas and classification of regions based on common
characteristics.
Continuous-wave (CW) tests are then conducted to synthesize models that closely
represent the propagation environment.
Traffic Modeling:
Study of demographics and running
population-analysis of designated areas to generate traffic models.
Coverage and Capacity Analysis:
Incorporate the above two processes in RF simulation tool
(Planet EV) to study the propagation and traffic patterns of the
telecommunication market. The study results in hardware requirement to provide
adequate coverage to the region with appropriate traffic and RF coverage.
