IEEE DySPAN 2008

IEEE DySPAN 2008 will provide the opportunity to conduct live demonstrations of dynamic spectrum systems and networks. This year's event will build on the huge success of the demonstrations at IEEE DySPAN 2007 by offering an invaluable opportunity to demonstrate, experiment, and interact with other world-leading researchers. This year's demonstrations will feature dynamic spectrum access, cognitive radio, and policy-based systems, prototypes, and critical technology components and algorithms.

In addition to pre-planned demonstrations, unique opportunities exist for experimentation by participants. These opportunities include general measurements of spectral activity during the demonstration and experimentation sessions; the interaction of various, independently-developed systems and networks; and the coexistence of systems using different spectrum adaptation algorithms.

Demonstrations Proposal Submission and Evaluation Information

Applicants completed the demonstrations proposal form to provide a description of the proposed demonstration and/or experimentation. The proposals were then evaluated by the DySPAN demonstration committee based on the following criteria:

Technical Significance: the extent to which the demonstration illustrates advances in dynamic spectrum access technologies.
Demonstration Maturity: the demonstration must be mature enough to leave the lab. Demonstrations involving RF transmissions must include a priori or in situ risk mitigation measures to ensure regulatory compliance and coexistence with other spectrum users.
Demonstration Supportability: the demonstration must be performed within the capabilities and resources of the DySPAN symposium. Demonstrations systems should ideally coexist with other potential demonstrations on a coordinated or uncoordinated basis.

Selected demonstrations will undergo a final review approximately 45 days prior to the symposium to ensure their operational readiness. Demonstrators are also encouraged to submit a two to four page demonstration overview to help explain their demonstration.

Accepted Proposals

All demonstrations applicants have been notified by email regarding the decision of the demonstrations committee. From these applicants, seventeen proposals from fourteen groups representing the US & Canada, Europe, and Asia have been selected. The current list of demonstration groups are:

Adaptrum (USA)
Real-time video transmission over TV white space without interfering with nearby TV sets.
Centre for Telecommunications Value-Chain Research (Rep. of Ireland)
1. A dynamic spectrum access network using cyclostationary signatures for network formation, network rendezvous and link maintenance.
2. The use of a static single carrier wireless communications link to facilitate transfer of software components to network devices that then reconfigure themselves to establish new communications links employing more advanced waveforms.
Centre for Wireless Telecommunications, Virginia Tech (USA)
1. A heterogeneous cognitive radio network enabling dissimilar cooperative spectrum sensing, dynamic spectrum access, and interoperability.
2. A dynamic cellular cognitive system (DCCS) designed to self-organize cognitive radios and other communication devices and to automatically form a dynamic cellular structured network.

Stevens Institute of Technology (USA)

University of Utah (USA)
Reliable detection of white space spectrum using a sensing mechanism with a high spectral dynamic range using embedded, real-time cognition algorithms.

Demonstrations requiring the use of licenced frequency spectrum are subject to the conditions of the FCC demonstration licence. Further details regarding the demonstrations will be added in due course.

Licence Information

FCC STA licence for IEEE DySPAN 2008 (WD9XIB)
Frequency (MHz)	Emission Designator	Authorized Power (ERP)	Station Locations	Effective Dates
482-500	6M00D7W 6M00D7W 6M00D7W 25K0F3E 12K5F3E 1K00NON	500mW	Chicago, IL NL 41-53-59; WL 87-37-24	Oct. 11 to Oct. 18, 2008 (0300 EST)

Omnidirectional antennas are to be used. The maximum effective radiated power (ERP) is 500mW; the maximum input power to an antenna with a gain of 3dBd (antenna gain with respect to a reference dipole antenna) should be 250mW therefore. Demonstrators should ensure that no out-of-band transmissions occur when operating near the band edges. This frequency range will be monitored continuously during the conference and if any interference occurs, the demonstration(s) and licensee will be subject to immediate shut down.

6M00D7W: 6MHz, amplitude and angle-modulated either simultaneously or in a pre-established sequence, two or more channels containing quantized or digital information,all information types.
25K0F3E: 25kHz, frequency modulation, a single channel containing analog information, telephony (including sound broadcasting).
12K5F3E: 12.5kHz, frequency modulation, a single channel containing analog information, telephony (including sound broadcasting).
1K00NON: 1kHz, unmodulated carrier.

Demonstration Pack

To help the demonstrators prepare for the demonstrations sessions, spectrum measurements and an example Matlab 3D plotting script have been made available. This information can be used to test systems using real measurement information from the conference venue prior to arriving in Chicago. In addition, this resource has been provided in the hope that if will also be of value to the research community in general.
The following figure is a plot of spectrum usage in the 400MHz-500MHz frequency range measured inside the Knickerbocker Hotel in Chicago (IEEE DySPAN 2008 conference venue) on March 23th and 24th, 2008. The frequency range licenced for demonstrations is highlighted on this figure between 482MHz-500MHz. Right-click and choose Save Target As or Open Link In New Tab or just simply click on this image to view the full-size version.

The demonstration pack requires Matlab to use the 3D plot generation script and measurement trace files.
