Big news at the IEEE mesh standards meetup last week in Denver, reports TelecomWeb and WiFiNetNews: a standard for mesh networking may be coalescing.
The new standard, 802.11s, will create a protocol for auto-configuring paths between access points over self-configuring multi-hop networks. With a standard, interoperatiblity between vendors may be possible.
Currently, all "city clouds" that use mesh networking to interconnect nodes use proprietary technology.
Placing a multi-million dollar bet on one supplier is asking for trouble. A mesh networking standard would likely lower both risk and cost.

ESS Mesh Networking Task Group Report
The ESS Mesh Netwokring Task Group (TGs) met on Tuesday,
Wednesday, and Thursday afternoon
7-9 March 2006 at the Hyatt Regency Denver Convetion Center hotel.
- The updated agenda for the meeting is in submission 11-06/256r10.
-
At the January meeting, TGs suspended its proposal selection process
to expedite the two remaining proposals, SEE Mesh and Wi-Mesh Alliance,
working towards a merger. This merger was successful and a single
joint proposal was presented and confirmed unanimously at the March
meeting as the starting point for the 802.11s standard, although
much work remains.
- TGs has scheduled three teleconferences on the following dates
at 11am US Eastern Time to discuss mesh security and its May agenda.
- 5 April 2006
- 26 Paril 2006
- 10 May 2006

Activities at the May 2006 meeting are expected to be to resolve informal internal technical review comments on its Draft, hear other technical presentations and possible amendments.
"Mesh-networking features will help keep IEEE 802.11, already dominant in the WLAN arena with over 100 million chip sets shipping annually, at the cutting edge of technology for the maximum benefit of its users,” says Mesh Networking Task Group Chair Donald E. Eastlake III. He adds that final approval of the new addition to the 802.11 family of standards is targeted for 2008.
SEEMesh (short for Simple, Efficient and Extensible Mesh) and the Wi-Mesh Alliance are apparently merging. SEEMesh is backed by Intel, Nokia, Motorola, NTT DoCoMo, and Texas Instruments. The Wi-Mesh Alliance is backed by Nortel, Philips, Thompson and Mitre. Details of the proposed standard are not yet available.
But the biggest names in the metropolitan-area mesh network space, BelAir Networks, Tropos Networks, and Strix Systems, are not buying in, reports Enterprise Networking Planet.

Strix and BelAir both have said that 802.11s may not cover outdoor mesh networking effectively.
Tropos, the mesh market leader, uses a single radio with their patented Predictive Wireless Routing Protocol (PWRP). Tropos may not feel compelled to jump in bed with the first mesh standard that comes down the pike.
In other mesh news, Trango Broadband Wireless is offering a wireless mesh system that can be used as a backbone ring (right). The new HD Mesh system creates a self-healing backbone ring network capable of speeds of "up to 45 Mbps". It is available for operation in the licensed 4.9 GHz public safety frequency band, as well as the 5 GHz unlicensed bands.
A total of six additional Ethernet devices, such as cameras and access points, can be added to Trango Broadband's HD Mesh micro-cell base station. It is designed to support WiMAX-ready radios and 802.11g Wi-Fi hotspots.

The Weekly Show

drawing from extrastruggle.
We've been having a back channel conversation amongst the trackers at unmediated about how/whether to update the way in which we aggregate, present, and make useable the content on the site, in light of all the various aggregators, digg and its clones, and role model group blog sites that we all consume/use/hate/love. Since we all primarily support open media movements and the freedom of bits and so forth, and with all of us being busy with our primary projects, we are looking for ways to make getting content on the site easier and more streamlined, while making it obvious that we are presenting other sources content. With the availability of open API's for just about any type of media aggegration literally getting past the saturation point, and mashups taking every possible form, we are wondering, is it time to take a step back, or a step forward with how/what we do at umediated? In the course of my surfing today, i found this new site, Boxxet Which just might be the straw that breaks the camel's back in how we all perceive the current mix and match nature of the web as it now stands. What's different about Boxxet from other aggregators and mashups like the newest entry popurls, (which aggregates digg, slashdot, reddit, newsvine, tailrank, and flickr) is that Boxxet is a Website generator. Thats right, just pop in all the urls u want to aggregate (and WHAT from them) choose how u want to format it, plug in the url that u want it to be accessed at... and whammo: Your own site with everyone elses content, and all thats left to do is decide whether googleplex or yahooza is going to be the source of your linklove revenue. And if u have on older domain that u plug this into...well, we all know how the pageranking with search engines work by now. It used to be that u had to have a bit of code knowledge to make all this stuff work. Eyebeam's Re-blog engine which powers this site was not a simple undertaking at the time that Michael Frumin and Michael Migurski put it all together... a half a year before Marc Broadband-mechanicked the term Reblog as his latest buzzword before casting his attention on the ourmedia-meme. (kudo's, kudo's) But now, with the cut and paste mentality of webculture that we at unmediated have helped create, the pace at which people are remixing and repurposing code is accelerating at a rate similar to the curve that we saw with pro-sumer desktop video... almost anyone can do it. I have this sinking feeling in my gut that we will arrive sooner than later at the same existential threshold that the film studios and record labels are squirming under to our joyful cries of "die, dinosaurs, die!". What i am wondering, is how long until my hero of the open-information movement, Cory Doctorow, and the rest of our pals at BB will tolerate re-aggregation and repurposing of his content, (now that he is investing so much more time at the site) before he (or any of one us) screams, "FOUL!" Stewart Butterfield over at Flickr is dealing with this beast at the moment...and i have to admire the dryness with which he states, "I loaded the FlickrCentral pool and firefox got up to using 240mb of ram before dying. So that's not a great user experience, but it's really terrible for Flickr. If it catches on and you don't limit it, we'll have to cut you off :\" Sure, Stewart, blame it on the user experience and firefox. ;) I admire your candor, and personal attention/approach to what has become one of the hottest new BRANDS in Web 2.0 ...that u still have time to be personal and all flickr-fuzzy even after being acquired, but I am sure that your jeans feel like they're fitting a bit tighter all of a sudden. Pretty soon, I expect, a lot of us bell-bottomed infornistas are going to wake up in a similar pair of Jordaches. I'm curious which of us will cut the inseams and sew in another totally different material to keep our style,and which of us will claim that now that we're wearing skintight jeans ("they're really really comfortable...REALLY! You think i should get a pair of Reeboks to go with 'em?"), that the manufacture of bell-bottoms should be forbidden. I point this all out in good humour only to illustrate a point: The times, they are('nt) a changin'>, and Cory just might wake up one day soon in his magic kingdom, and say "Hey, man, where'd all my whuffie go? And he's going to have no choice but to join Walt's pinstripesuits in pushing for copyright extension. It's a pill i hope he (and we) never have to swallow. So i pose the question to our community readers: How do you see unmediated-Are we crossing the boundaries in how we repurpose content? Would you like to see more editorializing? Narrower/Broader scope? Are we a repository of information that you come back to use, or just part of your daily information addiction? Let us know... I, for one, would like to have an idea about what pair of jeans to wear this year ;) michael
