★ Created best practice documents for LTE Small Cell Trials and Pilots group to enable drive test teams to have a single point of reference for commands and process for log collection, parameter changes, site outage detection, etc.★ Provided spectrum clearing analysis of CDMA 1x and EVDO systems to reduce the number of CDMA carriers making room to add an LTE carrier. This involved substantial analysis, interaction with the customer account team and participation in customer meetings. The effort resulted in getting NSN back into and leading the vendor selection for new LTE business.★ Served as Feature Architect for CDMA Alternative Technology Information Message (ATIM) feature used to indicate presence of an LTE system with the FOA taking place in Japan at the end of 2011.★ Performance author for the CDMA Origination Continuation Message (ORCM) feature. Created an equation to calculate the number of dialed digits that would fit into the Origination message given the ACH slot size and other optional message fields. Performed detailed analysis of field data for the number of dialed digits used to determine optimal parameter settings.★ Increased reliability of the EVDO product by collaboration with vendor to pinpoint the cause of call failures (CFC56 – lack of flow resources) to the APC card memory leak. Created Perl scripts to decode raw binary memory dumps from 3rd party APC logs to evaluate call management table entries and corrupted idle link list.★ Investigated and resolved a number of field issues. Refined Perl script to parse CDMA MIB data to generate KML file to be plotted using Google Earth to aid in field investigation issues. ★ Utilized OPNET Simulation to validate Smart SMS size impacts. Used the OPNET simulation tools and existing models to validate the impact of SMS message sizes on delay and dropped messages. NSN-J presented this information to KDDI so that they could manage the message size of their customers.
