In this post, Morfster wonders why industry isn’t taking a more active interest in participating in ITU-R activities related to SDR/CR, particularly the responses to the ITU-R inquiry into cognitive radio.
My 2 cents (spelled out more fully in the comments) is because the perceived benefit is negligible, any incurred costs make participating a losing business proposition.
An immediate question is why do I blog then? Because a) I wanted a place to keep track of links to everything I thought was relevant to cognitive radio and a blog is a convenient format, b) it does drive some traffic to the company website, c) the cost is negligible (5-10 minutes a day of my time).
Keith emailed to note that there’s going to be a demonstration track at this year’s DySPAN. Here’s some relevant details.

Probably nothing new for readers (both of you!) of this blog, but Cringely comments on the 700 MHz auction in Popular Mechanics here. I found his speculation on google’s plans the most interesting.
Having obtained some concessions from the FCC, Google apparently feels bound to bid at least the minimum $4.6 billion for one block of spectrum known as the C Block. The question is whether Google is actually bidding to win or simply bidding to make sure some of its open access requirements are imposed on an eventual winner, which will only happen under FCC rules if the bidding for that C Block goes to at least $4.6 billion.
Some pundits (that would be me) think Google will bid to win its spectrum block, then will trade that block to Sprint/Nextel for some of that company’s 2.5-GHz WiMAX licenses that are far better suited for data. Sprint Nextel, the number three U.S. mobile operator, is conspicuously absent from this week’s list of bidders, and its WiMAX strategy is in flux following the recent firing of CEO Gary Forsee, who was a big WiMAX backer. As the auction winner, Google could impose on Sprint Nextel its full open access requirements for the 700-MHz band (not just the limited access mandated for the band last year by the FCC), then extend that same access to its new WiMAX frequencies in a kind of one-two punch that would dramatically open up wireless data nationwide (that’s good for you and me). FCC chairman Kevin Martin was asked last week about just such a Google switcheroo and said the Commission would have no problem with it.
IJAACS has issued a call for papers on cognitive radio systems. Papers are due January 1, 2009.
Requested topics include:
- Signal Processing
- Channel coding
- Resource management
- Mobility management
- Energy management
- Cross-layer design and optimization
- Cooperation schemes
- Medium Access Control
- QoS provisioning
- Cognitive multi-hop networks
- Spectrum management (e.g. spectrum sensing, spectrum sharing)
- Model and performance evaluation
- Game theory in cognitive radio
- Standards, e.g. IEEE 802.22
- Regulation and business model
- Testbed, experiment, implementation, standards, and practical applications
The FCC says they’re resuming testing of white space devices.
Testing will begin Jan. 24 on a number of devices, including ones submitted by Microsoft, Motorola and Phillips. FCC chairman Kevin Martin had said earlier in the week that testing would begin by the end of the month.
The FCC commissioners generally agreed that there is a technological solution that will allow the devices to operate in the broadcast band without interfering with digital pictures. Broadcasters are not at all convinced, and they have lobbied hard against the devices, saying that any chance they could interfere with the DTV transition is too big a chance to take.
That spat between potential white space vendors and broadcasters is captured well in this article.
A “public misinformation campaign” by the National Association of Broadcasters has “confused the testing process” and misled policymakers, the Wireless Innovation Alliance said yesterday in a letter to David Rehr, president of the broadcasters’ association.
Broadcasters such as CBS and ABC oppose the plan, saying the gadgets may freeze the screens of consumers who get digital TV over the air. Sports leagues and Broadway theaters also want the devices banned, saying they may interfere with wireless microphones using the same frequencies.
White-space backers “cannot run and hide from the fact that their own technology utterly failed” FCC tests last year, Dennis Wharton, NAB executive vice president, said in statement.
Here’s the referenced letter (pdf).

Cognitive radio is a very popular topic at this software radio conference – there’s typically 20-30 papers directly on cognitive radio and everything else has a significant impact on cognitive radio implementation.
This is actually my favorite conference of the year because a) there’s a very good mix of commercial, defense, and academic publications and b) the numerous conference activities are conducive to longer discussions and I find I get the most substantive feedback on my research in the downtime between sessions at the SDR Forum than at any other conference.
In what I believe is a unique feature conferences, the SDR Forum includes a demonstration track.
I don’t know exactly what is meant by SDR 2.0 (was there an official 1.0 release? 1.1?), but then again I don’t really understand why the Web 2.0 label either.
Emerging Networks has a series of posts reporting results from spectrum occupancy measurement campaigns.
In this entry, they discuss the results of measurements taken during during Keith’s and Tom’s whirlwind tour of America.
In this entry, they report measurements from a drive across Ireland
Here they report measurements from Dublin.
Finally, in this post they discuss results of a campaign in Dublin performed by Shared Spectrum.
Jeff - CRT’s cofounder – started calling cognitive radio “the new MIMO” a few years ago because he thought that every conference was going to be shortly innudated with cognitive radio papers. Based on the last few days, I’ll say he’s right.
This morning, I received an email with a call for papers for ICST Qshine -the Fifth International ICST Conference on Heterogeneous Networking for Quality, Reliability, Security and Robustness. While workshop topics are still undecided, they’re explicitly requesting workshop proposals on cognitive radio and topics will likely be announced in February.
The conference will be held in Hong Kong from July 28-31, 2008 with papers are due March 10.
This is almost certainly too late for US and Asian participation, but European researchers may find it of interest. Yesterday, I received a rather late call for papers for CogART 081 -the “First International Workshop on Cognitive Radio and Advanced Spectrum Management” to be held in Allborg Denmark on February 14, 2008. Papers are due by January 21st with acceptance notification 10 days later. Requested topics include
- Dynamic spectrum sharing techniques and policies
- Interoperability, interference and co-existence of dissimilar wireless networks
- Spectrum measurements and sensing PHY layer design for cognitive radio
- Cognitive protocols and algorithms from PHY to application layers
- Cross-layer cognitive algorithms
- Applied mathematics for cognitive radio
- Application of machine learning and policy processing to cognitive radio
- Security issues
- Business and regulatory aspects of spectrum usage reform
- Software-defined radio Implementation, standardization, and certification of cognitive radio
- Cognitive radio prototypes
1. I assume an earlier announcement had to have been made, but I didn’t see anything until yesterday’s email.
I just got an email from the International Conference on UWB noting that there will be a track on “UWB Cognitive and Cooperative” which invites papers on spectrum sensing and dynamic spectrum access related to UWB (I’m not certain if MB-OFDM counts or if this conference focuses on impulse-UWB; based on the conference logo, it looks like both are acceptable). The conference will be held in Leibniz University in Hannover, Germany from September 10-12.
Here’s the full call for papers (link) and here’s the main conference page (link). Relevant dates:
- Papers submissions: Feb 10
- Acceptance notification: May 11
- Conference: Sep 10-12
I’ve been kinda lax about updating the CRT publications page, but as of today there’s four new CRT publications listed.
One is a paper I did with some folks from ETRI which was presented way back at the beginning of October at VTC.
Another is a paper I worked on with Youping Zhao (SSC), Shiwen Mao (VT), and Jeff Reed (CRT, VT) (we’re all Hokies) and submitted yesterday to an IEEE proceedings on cognitive radio.
The final two are documents which CRT contributed to the SDR Forum response to an ITU inquiry on cognitive radio, specifically on coexistence and spectral efficiency. Those will end up getting discussed at the next SDR Forum meeting. I don’t know that those sorts of things are typically published separately like this, but I think the SDR Forum responses will be of interest to the broader cognitive radio community and if you’re not involved in the ITU process or the SDR Forum response, you wouldn’t have access to them for better than a year, if ever, which I think is a real waste.
I can’t post others’ responses, but if other contributors make their submissions available online, I’ll link to them. And if and when the SDR Forum response gets posted online, I’ll try to link to that as well.
According to an email from Stephen Berger yesterday, the draft ballot for 1900.2 was successful (96% approval, with 76% of eligible ballots returned). It still needs to to go through the IEEE Standards Board for approval and publication, but the draft is out of the group. Berger also noted that further 1900 activities may be subsumed into SCC41, but that will be determined at a later time.
A reminder call for papers for CrownCom08 was emailed to me today. Here’s the official call for papers.
Basically anything related to the field of cognitive radio is considered acceptable.
- Full papers/tutorial proposals due: Jan 15
- Acceptance notification: March 1
- Conference Dates: May 15-17 (Singapore)
Papers are now due Feb 3.
