Panel Title: "Autonomic Communication and Wireless Cognitive Networks"
[Presentation]

Context : Smarter devices, converged networks and new service models are changing the way people communicate while on the move. Consumers and businesses are being offered new types of devices, new access methods, new services and applications, new subscriber models and more. At the same time, different standards continue to proliferate, new security vulnerabilities continue to emerge, and management challenges continue to grow. The rise of IP-based networks, combined with low-cost nodes and smarter devices, has moved virtually all processing to the network edges —democratizing access while creating new integration challenges. New wireless standards are creating revolutionary usage models, while also creating opportunities to innovate in challenging areas such as the management of connectivity, security and bandwidth. And all of these developments  are spurring network operators, service providers and users alike to extraordinary velocity in the adoption of new technologies.

It is complex but not chaotic : Although the complexity of both technical and business solutions/architectures seems to be increasing going forward, it is far form being chaotic. Seven trends has been identified to provide underplaying fabric of the observed wireless network evolution towards continuous access to communication and content, regardless of network, device or technology. It's these trends that will foster the development of technologies, standards and business relationships needed to create the foundation for Cognitive Networks and enable true seamless mobility .

1. Separation of Services from Transport: Interoperability of services is key – ensuring continuous access to relevant content – agnostic of the device or network.
2. System Diversification:  Creative business agreements and new technologies are constantly being introduced to bring "always connected," transparent, unrestricted connections to diverse services, content, coverage, prices and more.
3. Smarter Devices:  Blurring of lifestyles makes consumers don't differentiate between devices for work or play. Smart devices are designed and sold that deliver across experiences.
4. Mass Customization and Personalization: Consumers want products created just for them. Successful vendors will do this while making a profit via: 1) mass customization – when a manufacturer tailors a product with optional or add-on features; 2) end-user personalization – when the individual personalizes the product through add-on applications offered by the service provider.
5. End-User Simplicity: As gadgets become more feature-rich, users are demanding simplicity. But, simplicity means different things to different users. This appears to be universal requirement coming from all segments of the market and user classes – from techno-addicts to those in emerging markets.
6. Environmental Sensing: Radio Frequency Identification and GPS-based in-auto solutions are a sample of the devices that help respond to consumer needs. "Context aware" devices are key to seamless mobility experience – sensing environmental changes and adjusting accordingly.
7. Security and Reliability:Dependable, cross-network security is a must from both business and user experience perspectives. As consumers gain access to more networks and services, reliable security becomes a paramount issue for providers.

What are Cognitive Networks : Cognitive, wireless access networks are those that can dynamically alter their topology and/or operational parameters to respond to the needs of particular user while enforcing operating and regulatory policies and optimizing overall network performance. A cognitive infrastructure consists of reconfigurable elements and intelligent management functionality that will progressively evolve the policies based on the past actions.

The current wireless ecosystem consists of wide area networks such as 2G/2.5G/3G/3.5G, wireless local/metropolitan area networks (WLANs/WMANs), wireless personal area networks (WPANs) and short range communications, as well as digital video/audio broadcasting DVB/DAB infrastructure. Wireless solutions based on cognitive network principles encompass technologies and products to ensure that the networks, network components, as well as networked devices and applications, can be deployed and managed (configured, optimized, healed and protected), in real-time. Cognitive networks feature a distributed management functionality that can be implemented in accordance with the autonomic computing paradigm. The holistic, collective cooperation and action of the distributed, autonomic components yields a self-healing and scalable solution that accounts for the potential evolution of services and growing user needs.

Why Cognitive Networks : Wireless solutions based on cognitive network principles remove shortfalls of cooperative networks such as inter-operator dependencies, frequent infrastructure upgrades and challenges of split network management.

Cognitive networks would enhance operator's ability to:

Panel Title: “Cognitive Radio Dynamic Spectrum Access: Enablers and Future Architectures”
[presentation]

Context: The range of wireless communication services for which frequency spectrum is used continues to grow, while the demand for such services has seen a phenomenal increase in recent years. While rapid growth in demand for mobile telecommunications has been driving a large portion of spectrum demand, the growing popularity of entirely new applications, such as Wireless Broadband Access, are placing a greater burden on spectrum resources. Furthermore, most future scenarios predict an ever-growing plethora of wireless devices, where every consumer electronic device, every sensor or actuator is communicating wirelessly.

The traditional command-and-control spectrum management systems were motivated by the need to minimize interference between signals of different transmitters aimed at unintelligent receivers that were unable to distinguish between different signals on the same frequency range.  Furthermore the emphasis has been on broadcasting applications, such as TV and radio, where sender transmit its signal at the highest possible power in order to cover a large geographical area. The landscape of wireless communications, however, has changed dramatically:

Currently, regulator bodies, world over are in the process of modernizing their spectrum policies. The regulators are defining and exploring alternative spectrum management models which exploit the above technology advances in order to achieve a much more dynamic, distributed and decentralized framework for efficient utilization of the spectrum. Three distinct new models for spectrum management that are being considered by regulators are: the market model, the licences-exempt model(spectrum commons) and secondary usageof licensed spectrum by cognitive radios.

What is dynamic spectrum access?

An important consequence of reforms to spectrum policy is that they open up the possibility to exploit Dynamic Spectrum Access (DSA), an emerging paradigm in wireless communication and networking, which is expected to have a major impact on next generation wireless systems and services. The key characteristic of DSA systems is their ability to exploit knowledge of their electromagnetic environment to adapt their operation and access to spectrum. The key promises of these systems are that they open up the possibility of highly flexible and efficient management and (re)use of spectrum across all its dimensions. The cognitive radio, built on software defined radio, is the intelligent, adaptive and frequency agile wireless device that will underlie most forms of future DSA systems. Some forms of DSA potentially challenge operators while others may bring great benefits to them.

Panel objectives:

In addition to an array of regulatory and techno-economic questions that need to be addressed, the introduction of this new paradigm has resulted in new research issues and concepts. The focus in this session is to explore technological and regulatory aspects of cognitive radio DSA. The emphasis will be on a point of view from industry.  Specifically, we aim to:
