Workshop Synopsis

The concept of "Software Radio" was introduced in the early 1990s. Since then there has been significant research and development activity on software-defined radios (SDR). An important feature of the SDR vision is its ability to integrate legacy systems with newer and more advanced radio and access technologies. The work on SDR led to the realization that opportunistic spectrum utilization can lead to a dramatic improvement in the capacity of practical wireless network, and the concept of "Cognitive Radio" was born.

These ideas could not have come at a better time. The scarcity of radio spectrum and the resulting cost of provisioning wireless services have become an impediment to the growth of the wireless industry. As the services offered by the wireless communications industry continue to expand, so does the need for higher data rates both, instantaneous (to support real-time communication), and aggregated (to support the increasing pool of customers). Indeed, the use of the cellular spectrum has increased impressively in recent years, due to the introduction of new mobile wireless devices, and a large number of applications supported on such devices. Keeping these challenges in mind, a June 2010 Presidential Memorandum issued a call to "create and implement a plan to facilitate research, development, experimentation, and testing by researchers to explore innovative spectrum-sharing technologies".

The workshop on "Beyond Cognitive Radio" plans to examine novel and alternative approaches to cope with the challenges of wireless access, as exhibited by the shortage of radio spectrum. The intent is to consider approaches ranging from physical layer solutions up to application layer methodologies. Of particular interest are hybrid technologies, such as cross-layer design, which may facilitate performance benefits that are beyond the reach of solutions at any single layer. The format of the workshop will include "brainstorming" sessions, with focus on active participation of all attendees. Controversial topics related to the theme of the workshop are welcome, as are unconventional "high-risk, high-reward" approaches.

Attendance at the workshop is by invitation.
