Hardware Test Engineer, Co-op Student

• Mainly focused on USB, SD Card, and other Board modifications, exploring the hands-on Hardware and integration testing.
• Antenna Tool Calculator script tool was created to calculate the EIRP and TRP margin to maintain the FCC regulations and TMO/AT&T/Verizon carrier requirements.
• Focused on SD Card Troubleshooting, engaging with NXP semiconductors. EEPROM and NOR software flash and erase were performed for USB PD Controlled testing.
• Other tests for Stress and throughput verification were performed at different Voltage conditions for SD Card.
• Troubleshooting and debugging the test system while an error occurs on hardware and software during the functionality, performance, and test coverage
• Soldering Skills and Design understanding skills were enhanced while performing Board Modifications and Impedance Measurement tasks.

RF Test Engineer, Co-op Student

• Testing the AirLink routers – XR90, XR80, RV55, LX60 and their radio module EM9190 to verify the 3GPP Specifications and performing board modifications for improvising results.
• Writing test scripts in Python or using NI LabView for automation testing. Develop test system documentation for future reference.
• Candela Tech Chambers with 802.11ac and 802.11ax capable and LANforge as AP and Client was used to perform Wi-Fi Capacity and Rate vs Range test under Conducted, Radiated environment and live test.
• iQxel-MW LitePoint was used to verify the Wi-Fi Parameters – Power, EVM and Anritsu and R&S CMW500 - 5G and 4G Call was used to verify the Cellular Parameters - Maximum Transmit Power, Minimum Receive Sensitivity for all the supporting bands with the required Spec. values.
• Humidity Test with 95% humidity, 30 °C to 60 °C temperature range and Thermal Test under -40 °C to +85 °C temperature range depicting the real-time weather condition was performed to monitor the endurance of the units.
• Other test such as ESD – Air, Contact and EFT – Capacitive tests were performed at different Voltage conditions.

PCB Designer, Practicum

• The project aims to create a 6-axis robotic arm Artus Dex with high resilience, dexterity and 21 Degree of Freedom with a compact actuator driver. 
• The work assigned was to design an actuator driver PCB, incorporated with the position sensor AS5048a and an ODrive to simplify the assembly using KiCAD and Altium
• Designing a STM32F1 microcontroller along with its power electronic circuits for a mixed signal input.
• Troubleshooting and debugging the existing design according the size and time constraint and documenting the future in lab test for measuring the regulatory parameters.

Project Assistant

• The project in the 5G Testbed aims to develop an interface platform for smooth and feasible data transmission between the 5G Femto Application Platform interfacing MAC and the PHY layers in a communication network.
• Data transfer using 4 channels at the same time from host to card and card to host using a packet generator IP were executed for a large data, 8192 packets (131072 bits) using direct memory access in Vivado
• Additionally, VIO (Virtual Input Output) block was designed using Vivado HLS to manually alter the option of the file transfer and the latencies for every single case was calculated and compared.

Network Engineer, Intern

• The project assigned was in the field of Network Planning, where the planning was focused on LTE and 4G networks.
• Key insight was to identify the poor FDD (Frequency-Division Duplexing) coverage gaps in Chennai, which was enhanced by planning 197 new sites.
• Learnt Network function tools of the organization: SureCoverage, Google Earth, Facebook Network Insights.
• Quality factors- KPI (Key Performance Index) were analysed.
