The business model most often assumed is one where real costs for network build, share of internet backhaul and service support are distributed between its users. This works out expensively unless there is a high level of active collaboration, slow growth and carefully managed expectations of service. Even then costs and draw on time can prove exhausting. Boundless.coop is a large mesh network centred in South East London using MeshAP and attempting this balancing act; experimental mesh technology, inexperienced userbase and a highly competitive broadband market.

Well its better when you are using opensource/free software and where non proprietary componants are in use to contruct the system people can own and extend to suit themselves rather than to fit prescriptive models for profit. Wimax 802.16 and sibling schema are being engineered into propretary consumer electronic products tied end to end for profit and to obstruct lay entrepreneurship/enterprise. > > I have been reading about and creating mesh networks for a while now, > and I am fully convinced of the technology's usefullness, however > certain subtleties are flying over the heads of my advisors, and even > with pictures they are having a difficult time understanding the > concept. You should put all that reading to use and start building a mesh right away not least so your first hand experience can inform your academic aganda and convince your advisors.

In my experience the low cost in $ is quickly overrun by hight level of support and maintenance required.

Thanks in advance for any input. presume here you refer to point 2 point fixed wireless systems i.e. fixed frequency & licenced interconnection or stand alone access points on conventional backhaul - ADSL or cable.. where adding customers has a more linear cost implication than in a mesh network where client and carrier roles are more entwined. > Come to London next weekend 1st-2nd OCT and participate in a weekend debate and practice exploration of mesh networks - community action and much more.. during WSFII 2005 http://www.okfn.org/wsfii/ easy James > Sincerely, > Sean Fioritto From steve-consume at gbnet.net Sat Sep 17 12:21:07 2005 From: steve-consume at gbnet.net (Steve Kennedy) Date: Sat, 17 Sep 2005 12:21:07 +0100 Subject: [Consume-thenet] [MeshAPuser] fixed wireless costs In-Reply-To: <432BF6CD.9080400@spc.org> References: <5f1d9b0c050916174514d43906@mail.gmail.com> <432BF6CD.9080400@spc.org> Message-ID: <20050917112107.GB10428@gbnet.net> On Sat, Sep 17, 2005 at 11:58:21AM +0100, JamesStevens wrote: > > have not been able to convince my professors that mesh networking is > > better than other fixed wireless solutions such as WiMax or other > > proprietary systems. > Well its better when you are using opensource/free software and where > non proprietary componants are in use to contruct the system people can > own and extend to suit themselves rather than to fit prescriptive models > for profit.

WiMAX is as open as WiFi, it's just a new standard and there aren't that many chipsets available. The 802.16-2004 for FWA is an IEEE published spec. 802.16e (the mobile/roaming variant) hasn't even been ratified yet. > presume here you refer to point 2 point fixed wireless systems i.e. > fixed frequency & licenced interconnection or stand alone access points > on conventional backhaul - ADSL or cable.. where adding customers has a > more linear cost implication than in a mesh network where client and > carrier roles are more entwined. > Come to London next weekend 1st-2nd OCT and participate in a weekend > debate and practice exploration of mesh networks - community action and > much more.. during WSFII 2005 http://www.okfn.org/wsfii/ And maybe you can also demonstrate your 5.8GHz links that aren't registered with Ofcom (or at least weren't, allegedly).

I know marc send out some info about related events earlier on today - but I have an urgent request for all those of you with spare couches! We have a crisis of host shortage for WSFII - the World Summit On Free Informatoin Infrastructures, starting this week, and culminating next weekend (1st and 2nd). Due to insane London prices, Some of our people have been left without shelter! They're all clean, dangerously bright and well brought up, of course, and being on the right wavelength, they will almost certainly improve wireless signal reception in your home on a permanent or at least semi-permanent basis. Of course, London wasn't really the best choice of city for hotel affordability, and we've done the whole thing on a load of shoddily knotted shoestrings, cable ties and gaffer tape as usual. So - if anyone has a spare room from .. tomorrow (eep!) for one or two nights that would be *much* appreciated... Just mail me off-list, if you have a space to spare, and don't mind a lovely WSFIIer sleeping on your floor (or in one of the rooms of your castle). Free tickets to WSFII and other http://nodel.org/october.html events of your choice for all hosts + t-shirts, trinkets, glass beads, jelly and anything else we can find to thank you. X Saul. ----------------------------------------- and in case you borked at the html mail earlier, here's the WSFII bit: ----------------------------------------- ~ For redistribution far and wide ~ Register for the World Summit on Free Information Infrastructures! We are reaching maximum capacity; register *now* if you plan to attend. http://www.wsfii.org/register/ The World Summit on Free Information Infrastructures ( http://www.wsfii.org/ ) is happening in London, 1st-2nd October 2005. Wsfii will bring together pragmatists and innovative practises from across the world, from free wireless networking and open hardware. free maps, free media, open civic information, and community currencies. A provisional programme is available here: http://www.wsfii.org/programme.html The event is open to all but you *must* register if you plan to attend because space is limited. A Wsfii membership fee of ten pounds is expected to help pay for costs: ask about concessions if you can't afford it. Wsfii is the kickoff event of the NODE.london Open Season on technology, media, art and politics, happening throughout this Oktober. Highlights: * Future Wireless at the Science Museum - http://cybersalon.org/ * Open Congress at Tate Britain - http://opencongress.omweb.org/ * Gilberto Gil, Minister of Culture, talking about the Brazilian goverment's adoption of Open Source Software and Culture more info at: http://nodel.org Wsfii Info ============ What: World Summit on Free Information Infrastructures (WSFII) Url: http://www.wsfii.org/ Programme: http://www.wsfii.org/programme.html When: Saturday and Sunday, October 1-2 2005 (2005-10-01 -> 2005-10-02) Where: Limehouse Town Hall, 646 Commercial Road, London, E14 7HA Map: http://tinyurl.com/7m5qw Registration: http://www.wsfii.org/register.php -- -- http://chinabone.lth.bclub.org.uk/~saul/ ----- End forwarded message ----- -- -- http://chinabone.lth.bclub.org.uk/~saul/
