May 2015 - Aug 2015
At Innovative Wireless Technologies I worked on numerous projects. One project I worked on was testing underground radio equipment to see if it could be implemented in other similar scenarios. Another project I worked on was coding and creating a spreadsheet in Excel and VBA in order to simplify the expense report system. Along with these projects I worked on numerous other small task, such as testing new firmware patches, assembling multiple integral parts to IWT's Mining Communications system, and learning about their mesh network system.
