IIT Real-Time Communications Laboratory

About the RTC Lab

The Real-Time Communications (RTC) Lab at the Illinois Institute of Technology (Illinois Tech) is an educational facility dedicated to teaching, research and development activities that further the advancement of networked communications. The lab welcomes projects from partners in industry and academia provides a unique venue in which industry and academia connect and collaborate. The RTC Lab is affiliated with Illinois Tech's Wireless Network and Communications Research (WiNCom) Center and is directed by Carol Davids, and Vijay K. Gurbani. The RTC Lab collaborates closely with Illinois Tech's Active Computational Thinking (ACT) Center.

Areas of research include:
  • Indoor Location for Emergency Response using BlueTooth Low Energy beacons and Wifi
  • WebRTC Solution for Next Generation Emergency Communications
  • Multimedia signaling performance benchmarking
  • Application of machine learning techniques to real-time communication networks and VoIP
  • Natural language understanding/processing pipelines in real-time communication systems


The RTC Lab is directed by Carol Davids and Vijay K. Gurbani, faculty members in IIT's Computer Science Department. Carol Davids designed the RTC Lab in the early 2000's to support the weekly hands-on assignments and semester projects essential to her real-time communications and networking courses. Soon the lab became a venue for projects proposed by industry- and academic partners. Before joining the faculty at IIT, Carol worked at Ameritech, Motorola and Tellabs. Vijay Gurbani's work also spans both industry and academia. He has worked in industry at Fermi National Labs and Bell Laboratories and is currently Chief Data Scientist at Vail Systems, Inc. Professors Davids and Gurbani have worked together for many years, collaborating on research, publications and conferences. They plan to expand the scope of the lab's work to include the integration of VoiceTech, BlockChain, AI and IoT with Real Time Communications technologies.


The RTC Lab is managed by Joe Cusimano. He maintains the lab resources, mentors lab students and interfaces with our industry partners. Joe oversees the operation of the NG9-1-1 Test Bed in the RTC Lab, where the National Emergency Numbers Association (NENA) holds its periodic Industry Collaboration Events (ICE). Before joining the RTC Lab, Joe worked for many years supervising operations in Illinois Bell/Ameritech, and currently is the principal consultant at Elec-Tel Communications.


Students are at the heart of the lab's activities. Lab assignments and semester projects associated with courses are done here. Students also engage in all the events and activities of the lab. They support and participate in the lab's public events including the annual RTC Conference, STEM Week and the Ethics and Technology Panels. Students also provide support for industry-focused activities including NENA testing events, ClueCon, and TADHack.

Here are some videos made by IIT Graduates who describe how their work at IIT and in the RTC Lab has helped them in their careers.


Upcoming events:

  • October 2-5, 2023: Real Time Communications Conference at IIT - an International Conference of the IEEE a globally recognized collaborative event, where industry and academia connect. Held on Illinois Tech's Main Campus in Chicago, this event will be face-to-face this year. Visit the RTC Conference and Expo website to view a description of the tracks on the Program tab and to find the schedule when it is available . Meanwhile, please visit last year's website at RTC Conference and Expo-2022 where you can find a list of speakers, including recordings of their presentations.

    The link the Call for Papers is at Call for Papers These papers will be peer reviewed and papers that are accepted and presented by an author will be submtted for publication to IEEE XPlore archive.

    A call for talks and demos related to the conference scope will be issued soon. These talks and demos can serve as a source of new ideas and research partners in industry. Presentations and demonstrations will be selected by the RTC Conference Track Chairs and Steering Committee based on relevance and technical content.
