<div>Hello erico</div><div><br></div><div>as harald already provided u with many gerneral information, i will know focus just on prices and some links to recommandable hardware and combinations,..</div><div><br></div><div>

<div>Thanks, that was a complete answer - I was actually thinking more about memory and processing requirements.</div><div><br></div><div>Arm is something we are looking at right now, but we have two problems:</div><div><br>
</div><div>1 - Our projects do not aim to result in million products or something like this, we will use really small quantities during development and not a lot processors after when shipping the products - they are meant to provide web/connected access to small cities AFAIK... </div>

<div>So no company is really interested in providing us development kits and processors - with a reasonable lead time.</div></blockquote><div>hmm many devkits are readily available in single quantities.</div><div><br></div>

<div><br></div><div>2 - Other bigger developers are not interested in sharing the discoveries they have made, so having a start point it's being difficult.</div></blockquote><div>so u might have to buy complete products (e.g. ubiquity has many nice & still reasonable priced ones,..)</div>

hmm i think your hardware option this depends mostly on how much money u want to spend,.. *G</div><div><br></div><div>here some examples out of of the super cheap but recommandable mips based router hardware,.. (mixed/compared with arm stuff *G)</div>
<div><br>20€ quite capable hardware (same as in "newer/faster" ubiquiti outdoor devices), but as soho router in an indoor case, (e.g. tplink wr741nd)<br>25€ --,,-- same with additional usb port (tplink aswell)</div>
<div>30€ device with outdoor case, but slow/limited) (e.g. ubiquiti bullet)</div><div>35€ outdoorcase, integrated antenna, but slow (e.g. ubiquiti nanostation loco)</div><div>50-75€ "newer/faster" ubiquiti outdoor variants (nanostaion m2, bullet m2, airgrid, nanobridge)</div>
<div><br></div><div><div>10€ for a "good" usb wifi (with removeable antenna!) (e.g. 8€ Tplink TL-WN722N atheros, 12€ Edimax EW-7711Usn ralink)</div><br></div><div>40€-100€ cheapest arm-boards available in small quantities (ethernet, usually 2x usb, defintiely more performance than anything above, and less power consumption aswell) <br>
but theese boards might require addtional daughterboards to be "easy" useable, <br>but imho a (complete) custom board layout is surely not really required for your intended use,..</div><div><br></div><div>some examples:<br>
99€ <a href="http://www.ic-board.de/product_info.php?info=p105_ICnova-SAM9G45-OEM.html">http://www.ic-board.de/product_info.php?info=p105_ICnova-SAM9G45-OEM.html</a> (they have a quite nice 29€ "development/breakout" board)</div>
<div>$99 <a href="http://www.embedinfo.com/en/list.asp?id=75">http://www.embedinfo.com/en/list.asp?id=75</a> </div><div><a href="http://www.variscite.com/products/item/32-var-som-am35?gclid=CIXexo-X0acCFQsJ3wod40wYCg"></a>$139 somewhat nicer 2.54mm "pinout" <a href="http://armkits.com/Product/mini6045.asp">http://armkits.com/Product/mini6045.asp</a><br>
<div>$49 (cortex a8!), sodimm interface <a href="http://www.variscite.com/products/item/32-var-som-am35?gclid=CIXexo-X0acCFQsJ3wod40wYCg">http://www.variscite.com/products/item/32-var-som-am35?gclid=CIXexo-X0acCFQsJ3wod40wYCg</a> (i`m not sure about the minimum quantity there (if u find out pls let me know *GG))</div>
</div><div><br></div><div>based on such core-boards, u can design a quite simple custom breakout/daughterboard yourself, or just use exisitng ones.</div><div><br></div><div>to sum this up,..</div><div><meta http-equiv="content-type" content="text/html; charset=utf-8"><div>
(i´ll sum this up for triple wifi nodes, but of course u can build nodes with this components with 2 antennas usually for 70-85% of the price, or 4 antennas for 110-130%)</div></div><div><br></div><div>based on an 25€ tplink router (with 2 usbsticks), u can get a 3 wifi setup with 400mhz mips24k and 32MB ram for less than 50€ (without antennas and casing))</div>
<div><br></div><div>or if u need/want more performance (less power consumption), probably longer lifetime, or much more expanding possibilities u might get away with 100€ for an arm based solution,.. (not if u want to build a single node)</div>
<div><br></div><div>both above options will require at least 50€ more to get power supply, casing #1 and 3 accpetable/bad *g antennas *G</div><div><br></div><div><meta http-equiv="content-type" content="text/html; charset=utf-8">but 100/150€ for a complete triple wifi node isn`t that bad, imho,..</div>
<div><br></div><div>or u take 3 ubiquitiy devices, and end at 150-200€ (or 100€ if the old 16MB ar23xx <=200mhz mips4k ones are acceptable) + an indoor switch </div><div><br></div><div>a good option would be to use the tplink in an outdoor casing or an antennabox #1 as a "base" to add ubiquitiy routers and/or maybe usbsticks, to form an very flexible node setup,..</div>

<br></div><div>p.s. you`ll find many more links similar to above on <a href="http://alpenrouter.xaok.org">alpenrouter.xaok.org</a>,.. (which is mostly written by me *G)</div><div>and hopefully soon some more details and driver patches for EW-7711Usn (a recommendable usb-stick *G) <br>
and netusg20 (not really recommendable 400mhz arm9 board *G) , if i find time to create wiki-pages from my notes *G<br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
