CogNeA Updates

Posted in CogNeA, companies, standards, white space at 3:51 pm by JamesNeel

(link) CogNeA is pushing their standard into ECMA.

CogNeA contributed its specification to Ecma’s TC48-TG1 that will further develop it and plans to finalise the 1st edition for publication by the end of 2009. The Standard comprises Physical (PHY) and Medium Access Control (MAC) layers that include interference-avoidance mechanisms. The Physical layer, interference-avoidance and cognitive radio technologies, will be specified such that other wireless networking standards, looking to operate in the TV whitespaces, can use it.

(link) Wi-Rider is a new Georgia Tech spin-out that looks like it’s coupling a REM-like collection of databases with a networked centralized manager for radio resources. Here’s their tech brief. Based on their website’s presentation, I think this is intended as a piece of CogNeA.

Georgia Tech issues CogNEA press release

Posted in CogNeA at 8:05 am by JamesNeel

(link) Yesterday, Georgia Tech issued a press release announcing their membership in CogNEA.

There’s nothing new in the announcement that we didn’t cover earlier, but at least it confirms that I’m not crazy as until now this blog seemed to be the only primary source of information online until now.

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.

UHF Cognitive Networks Alliance (CogNeA)

Posted in CogNeA, cognitive standards, white space at 6:01 pm by JamesNeel

I was just emailed a press release announcing the formation of an industry group to define a protocol (PHY / MAC) for white space data networks.

They hope to have a draft standard for comment available in the first half of 2009.

Since I don’t have an external link, I’ve put the press release below the fold.
