Center for Research in Knowledge Communications (CRKC)

  • CRKC researchers generate solutions for the current and future technical challenges in those areas of technologies, systems, and network architectures that enable the vision of the information age. Industry often brings a different perspective to research problems and pushes for high-impact, innovative, yet applicable solutions that can be implemented in real-life systems.  Evaluating the potential for reduction to practice and providing high-impact solutions to a broad community, which are often key elements in industry collaborations, are significant parts of most of our projects.


  • Merging fundamental research with real world applications, our research group attempts to improve the performance and reliability of networked systems; spanning areas of communications, information processing, and data storage - defence and national security - health and medicine - advanced measurements and applications.


  • CRKC activities include feasibility studies, applied research, software development, hardware prototype development, and education and training. It is one thing to have a good idea, but another thing to put it into a prototype.

Origins of WiFi

Dr. Kavehrad had a pioneering role in creation of "WiFi" as in several published papers in early 1980s and by a real feasibility model development, at Crawford Hill Bell Labs in Holmdel, New Jersey, he proposed the first wideband Direct-Sequence Spread Spectrum (W-CDMA) wireless systems with multipath resolution/combining capable receivers with multiuser CDMA base-stations for Voice, Data & Video transmissions inside buildings (Origins of Hot-Spots and WiFi). This was accomplished well before the activities of Qualcomm and other companies in mobile cellular and wireless LANs applications. These demonstrations, speeded up the FCC allocation of ISM bands. IEEE 802.11b Standard has its roots back in these works. Later, many industries followed these patented works to the product level, e.g, Apple, Qualcomm and Lucent Technologies, etc.

For technology transfer in 1991, Kavehrad formulated a workshop called "Spread Spectrum Potential Commercial Applications Myth or Reality" in Chateau Montebello, Quebec-Canada whose participants were renowned contributors to this field.
