Wi-Fi Technical lead

My responsibilities:

  • Current tasking requires me to find and develop tools, refine testing techniques, and document processes for Wi-Fi and Wi-Fi/Bluetooth coexistence devices. Tasked to create several different testing and training strategies for various Wi-Fi equipment that can associate and connect to Wi-Fi access points, Wi-Fi Direct and hotspot/tethering devices. This is done for commercial, home and automotive devices that support data and multimedia uses. Write clear and concise technical documentation to encompass our Wi-Fi and Wi-Fi/Bluetooth coexistence testing capabilities and strategies for sales, QA and Business Development teams. Create a comprehensive Wi-Fi training course for in house for engineers and technicians from novice to expert levels. Review WLAN services offerings to ensure up-to-date technologies and testing are supported.
  • Continuous review of WLAN services offering
  • QA Engineer and QA Technician training
  • Test solution provider
  • Sales and BD support
  • Technical input for WLAN testing and Bluetooth coexistence issues
  • Technical resource for Sales, BD, PMs, and QA engineers
  • Detailed root cause analysis RCA
  • High level consultancy
  • We first test Wi-Fi and Bluetooth unique functions individually. This simplifies the troubleshooting and isolates Wi-Fi or Bluetooth issues prior to coexistence testing.
  • WAN performance and interoperability testing using Linux based NetEM and TC is used to evaluate the impact of injecting the environment variables latency, jitter, and packet loss.
  • DUT to AP throughput testing is performed with various packet types, sizes, and loads with tools including IXIA Chariot and Iperf.
  • Video and audio for Wi-Fi devices are tested and evaluated for robustness by a locally created ITU based MOS system. Testing is performed with popular player softwares.
  • Testing scenarios that cover Wi-Fi hardware, developed and designed by our customers and their vendors, requires many different indoor and outdoor testing environments. A/B/G/N/AC radio requirements, various countries' regulatory domains, DFS, international channels, mobile mesh technology and antenna geometry all require unique setup and testing.
  • Security and certificate based testing infrastructure includes various Microsoft and open source based PKI configurations. Our infrastructure allows for thorough testing of HTTPS, 802.1X and other certificate based security. Standards based encryption of wireless data requires the testing of all permutations of encryption engines and DH key sizes, 802.11, WEP 64/128, WPA, WPA2, TKIP/AES and 802.1X support.
  • Each wireless hardware device is tested for every supported element of an access point, Wi-Fi Direct Connect and Mobile Hot Spot/Tethering functions. This may require testing of DNS, DHCP, Unicast and Multicast for IPv4 and IPv6, Radius server and client, local and remote authentication and the new OSI layer 3 Wi-Fi TCP encoding.
  • Wi-Fi/Bluetooth coexistence testing, for coexistence devices, tests transitional robustness of each element during various user scenarios. Testing Bluetooth interoperability with various Wi-Fi configurations involves a plethora of Bluetooth devices of various technologies and complexity.

Owner/Lead Technicial Analysist

I had been tasked to create, rewrite, and to define metrics for various engineering and business requirements in support of the development, testing and deployment of Progress Energy's Next Generation Demand Response residential switch. I also developed the requirements for building an in house testing facility from development to deployment, and a deployment test facility for sample testing devices for verification of vendor compliance. The purpose of the switch is to allow remote control of various in home appliances by Progress Energy during extreme grid events to smooth dramatic spikes. The new Smart Grid switches will be a bidirectional 900 MHz. wireless mesh devices offering a better understanding of consumer energy needs with 21st century appliances. These devices will offer future expansion allowing Progress Energy customers granular scheduling control for advantageous energy pricing time slots. The business requirements define the switch functions and business needs of the device to support local, state, and federal laws and guidelines for such devices. The wireless, electronic, electrical, and physical engineering requirements will be used by vendors to design and construct devices for Progress Energy. The requirements will also be used to define a testing strategy with explicit expectations from in house testing and validation/verification of 3rd party testing and compliance.

  • I either led or Participated in the following activities in the performance of my job:
  • DLC Switch and RDR Deployment Workshops DLC Switch Technical Evaluation Team meeting
  • Various business Process and vendor selection meetings.
  • RDR Switch Comprehensive Test plan and Detailed Test Plan development.
  • Review CaliberRM for RDR/DLC requirements.
  • Published Switch requirements from CaliberRM to HPQC for test case development.
  • Outline to major elements for scheduling of Unit and Integration Testing.
  • Participated in Configuration Management Plan Review
  • Continued identifying required test devices and equipment for in house lab testing.
