Technology Design Engineer - III (2 year 2 months)
Develop designs using AirMagnet Survey Pro for indoor and outdoor wireless LAN network deployment and evaluate the optimal combination of acquired information and contributing data to develop final design.
Measure and visualize heat maps for Signal, noise, signal/noise, wireless network throughput, PHY data rates, retry rates, and packet losses.
Effectively manage areas of design responsibility and simulate “What-if” scenarios to minimize wireless site walks.
Perform material take-offs and cost research for wireless technology infrastructure estimates.
Customize wireless survey reports for efficient hand over of results based on wireless LAN application requirements.
Minimize expensive wireless 802.11n/a/b/g/ac LAN performance impact due to RF interference sources by performing simultaneous wireless heat map spectrum analysis in AirMagnet Survey Pro.
Using AirWISE engine, set wireless network design/application requirements including signal coverage, wireless network throughput, PHY data rates, 802.11n/ac specific parameters, etc. for the network and immediately identify any problem areas.
Demonstrate attention to detail and perform company Design Quality Assurance (DQA) to ensure high quality work. Projects:
