CogNEA Update

Posted in CogNeA, CRWG - cognitive radio work group, white space, white space test group at 6:24 pm by JamesNeel

Pat Carson from TDK gave a short presentation on CogNEA today at the SDRF CRWG / Secondary Spectrum Test Group joint meeting and said the information was for public consumption, so here’s some info in addition to the earlier press release.

1) CogNEA is basically the technical side of the White Space Coalition (the lobbying side). (TDK was a member of the WSC)

2) CogNEA is nominally now “open” for membership, but the new membership process has not been defined.

3) The standard CogNEA is developing defines a PHY, a MAC, and the extent of the cognitive capabilities is geolocation + sensing. Unlike the 802 ECWS plans, there is no current plan for the standard to have [explicit coexistence capabilities - ed, wow, I left that sentence unfinished for a week.]

4) CogNEA is intending this for the following applications: In-home High Definition MultiMedia (HD MM) but not wireless HDMI, Networking and distribution solutions that overcome the whole home coverage problems inherent to solutions using ISM bands, Internet Access for communities, neighborhoods, campuses, Ad-Hoc Mesh networks, Tele-health, Home automation and control. Currently these are handled by different standards (e.g., Zigbee, WiFi, Bluetooth) but the PHY is intended to handle everything (basically WLAN and smaller).

5) The Standard was at V0.70 the last time Pat checked, but it may have been updated at the ECWS meeting (the CogNEA meetings have been going on as sidebars at related meetings). The plan is to bring it to a SDO such as ISO in mid-2009.

Cognitive Radio Activities at SDRF / JSTeF San Diego Jan 09 Meeting

Posted in conferences, CRWG - cognitive radio work group, shameless self-promotion, white space test group at 12:58 pm by JamesNeel

The agenda for the next SDR Forum meeting has been posted. It’s in San Diego from January 26-30 and will be co-hosted with the JTRS Science and Technology Forum.

The following cognitive radio related activities will go on:

CRWG Meeting

The Cognitive Radio Work Group will be meeting primarily to continue putting together an extensive survey document on quantifiable benefits of cognitive radio for later use in ITU submissions and position papers as well as general evangelization on cognitive radio

White Space Test Group

The White Space Test Group will be meeting primarily to work on use case documents for input to the 802 ECSG on white spaces and for later SDRF development of test specifications for white space devices.

Meta-language for Mobility Work Group

I’m not certain what the MLM group will be doing as they just finished up a use case document (where can meta-languages help supprot cognitive radio). They generally coordinate with 1900.5 and may be working on specifications. (Oddly, I only have so many hours in the day and can’t participate in everything)

Public Safety SIG

While dealing with more general public safety comm / SDR issues, at least some of their meeting time will likely be used to work on their cognitive radio use case document (intended to help identify required technologies / insertion points).

Cognitive Radio JTRS SBIR Briefings

Shared Spectrum and CRT (us) will each give 20-minute briefings on our JTRS-sponsored Phase I SBIRs on cognitive spectrum management.

I’m not certain what they’ll speak on, but I figure it’ll be on policy and DSA. Their open abstract is here.

We’ll talk about distributed non-collaborative spectrum optimization / management of MANETs and what we did in Phase I (our open abstract is here). Besides the big benefits for managing an integrated network, we think our little algorithm suite will be particularly useful for coexistence of white-space devices running incompatible waveforms, so we might touch on that some too.

SDRF White Space Testing Group Starts

Posted in cognitive standards, white space, white space test group at 7:30 pm by JamesNeel

While I’m mentioning cognitive radio groups starting up, the SDRF White Space Testing Group had its first official meeting a couple weeks ago (unofficial meetings had been going on since mid-summer). Right now it’s focused on developing / documenting use cases for white space (beyond “WiFi on Steroids”). This is primarily intended to help develop testing recommendations for white space devices, but will also probably feed into the 802 ECSG on white space mentioned below, which will also be starting with use cases.

The press release announcement is here.
