Over the years, the WolfTech IT division of the Department of Electrical and Computer Engineering has produced a portfolio of systems and online tools now widely used across the entire NCSU campus — examples include the campus digital signage system, Billboard, which currently powers over 500 digital signs displaying 4000 unique slides for 50 units across NC State’s campus. In addition, the Wolftech Active Directory domain, created to support the Windows computing needs of the department in May 2005, grew to support multiple colleges, and finally in March 2009, was adopted as the campus standard — it currently supports over 16,000 computers on campus.
