Testing satellite dish links today

by Marc Juul

Just a reminder that those of us who are interested are meeting at 5 pm at sudo room today and heading down to lake merritt to see how far we can make a connection across the lake. We're using two satellite dishes mounted on small platforms, each equipped with an aiming device and a wifi usb adapter. The wifi usb adapters are 802.11b/g/n compatible and claim to be 1 watt: http://www.amazon.com/Etekcity-Wireless-Network-Adapter-Antenna/dp/B006JWMO… So far they seem to at least be better … [View More]

Seattle mesh group

by Marc Juul

I was talking a bit to the Seattle meshing group the other day, and they have some interesting info on their wiki: https://wiki.projectmeshnet.org/Software_Projects https://wiki.projectmeshnet.org/Projects https://wiki.projectmeshnet.org/Hardware I'm not sure I believe the claims of 15 km or 3-10 km. Maybe in a theoretical ideal situation, but definitely not in an urban setting. In any case, we should see how far two Ubiquiti Nanostations can link in an urban setting. Here are the … [View More]

I cant make tonight but I will bring my router and a laptop tomorrow. Anyone configured a router yet? Has there been any meshing at sudo room? Id like to know which protocol to start configuring tonight so we can mesh tomorrow. If you dont mind a temporary node to add to your tables. Sorry I cant leave the router. I need it for my home mesh. :/ Also, does anyone think its a cool idea to have mesh meetups wednesdays AND thursdays (semi-officially)? Would avoid confusion and maybe increase … [View More]

$26 OpenWRT router

by Miguel Vargas

I went looking for cheap wifi routers that can run OpenWRT and came across the TRENDnet N150 which sells for $26. http://www.amazon.com/dp/B00979B8D8/ref=cm_sw_su_dp It only has 4MB flash and 32MB RAM, but that might be enough. It uses Qualcom's Atheros chips which seem to be well supported by OpenWRT. TRENDnet is marketing it as an "Open-source wireless router for Linux developers and open-source enthusiasts". I'm going to go ahead and buy one so we can play with it and try to get batman-adv on it.

Mount Pleasant Mesh network

by Miguel Vargas

I came across the story of this neighborhood mesh network in DC and thought I'd share. They're using Commotion firmware on Ubiquity routers. They've only managed to get a handful of nodes up but I think their experience is informative. I like his posts Start With People and Treat it like Infrastructure, http://mountpleasantcwn.net/blog/ This marketing doc is good, https://docs.google.com/file/d/0B3YVvUQQSjTpTkg5YkxNLXVXR3M/edit?pli=1

Action Items! & Meeting Minutes

by Jenny Ryan

Rad meeting tonight! Here are notes, which shall be cross-posted to the wiki: http://sudoroom.org/wiki/Mesh =Action Items= ==Immediate== *OpenITP Grant - throw in your thoughts! - https://pad.riseup.net/p/510penITPapp - due March 31st *Market research on 4MB routers that will run OpenWRT *Juul will research binoculars and send info to Mark (carryover item) *Testing with satellite dishes - in sudo room next week! (after the main meeting) ==Longer Term== *Send out map and work on it *Update … [View More]website **Commenting on nodes (Revent, Tidepools) *Come up with a handout for going door-to-door =Attendees= Jenny, Miguel, Mark B, Bill, Jordan, with some OaklandWiki meshing ;D, =Notes= *How the site works: **Create an account and put in the MAC address of the mesh router **Allows us to build a list of all the routers on the network *openmesh firmware runs a shell script when first installed, connects to openmesh.org and our own instance, 510pen, is recognized and fed directly to the router *How the portal currently works: **Pushes the HTML to openmesh.com if it updates *How the portal could work: **Data source on the mesh, some IP, every router could use static pages (using javascript restful endpoints) *We should get more routers! 8MB preferably, 4MB might work *We'd need more CPU - WRT4GL's should work - CPU can easily be maxed out depending on size of the mesh *Installing fibre along International Blvd - a highspeed access point would make it worthwhile to shoot across the city *Research fibre in East Oakland *Mesh nodes for GSM *RanchWiFi - Solar ISP - Matt's connection *Sudo GSM! We use all the protocols at sudo!! *Old Sonic routers?? **Opt-in with Sonic? - Dane Jasper *Should we abandon OpenMesh and flash routers with our own firmware? At the very least, we should field test the firmwares out there. *OpenMesh used to use OLSR, and is proud to have switched to batman-adv *802.11s - mesh standard - what's the deal? *BattleMesh!!! 4/20 in Denmark - we should keep tabs on how that pans out. Or.. go? =Reportbacks= *Jenny followed up in #oti on weatherproof equipment Ubiquiti equipments *Jenny and Mark B presented 510pen at Open Oakland. *Follow up with Tony on Cisco connection - "how many routers do you need?" he asked at Open Oakland meeting. Mark's answer, "ideally, one in every other house." *Bill did not flash the router ;) but his Coursera course is ending soon! bOm, Jenny http://jennyryan.net http://thepyre.org http://thevirtualcampfire.org http://technomadic.tumblr.com `~`~`~`~`~`~`~`~`~`~`~`~`~`~`~`~`~`~` "Technology is the campfire around which we tell our stories." -Laurie Anderson "Storytelling reveals meaning without committing the error of defining it." -Hannah Arendt "To define is to kill.

Inquiring on weatherproof equipment in #OTI

by Jenny Ryan

I chatted in #OTI today re: weatherproof equipment. OTI (Open Technology Institute) is the org supporting the Commotion project. It was suggested that more support could be garnered through joining the commotion-dev mailing list: https://lists.chambana.net/mailman/listinfo/commotion-dev ------------------------------------------- (12:32:35 PM) tunabananas1: I am seeking suggestions for outdoor weatherproof equipment for mesh setups! ping jrbaldwin1 (12:42:52 PM) andygunn: tunabananas1: What … [View More]info do you need about mesh equipment? (12:43:15 PM) andygunn: We usually use Ubiquiti equipment, since it is our development platform for Commotion stuff (12:52:54 PM) tunabananas1: andygunn: so in the wild ubiquiti APs need no additional weatherproofing? (12:53:16 PM) andygunn: Nope. If you use the outdoor rated equipment from Ubiquiti, they are fine (12:53:27 PM) andygunn: Most of their gear is outdoor, they only have a few things that are indoor (12:53:36 PM) andygunn: Such as some switches, routers, a few access points (12:53:54 PM) andygunn: All PicoStations, Rockets, Nano_ units are outdoor rated (12:54:21 PM) andygunn: As long as outdoor rated Ethernet cable is used as well, most installs are fairly weatherproof (12:54:46 PM) andygunn: In fact, additional weatherproofing (such as mastic or caulk) can cause issues with water ingress (12:56:07 PM) andygunn: One caveat: Ubiquiti Bullet equipment may require additional weatherproofing (12:56:07 PM) tunabananas1: good to know! i will share with the 510pen team (12:56:17 PM) andygunn: depending on the antenna they are attached to (12:56:27 PM) andygunn: the N-type connector isn't 100% waterproof (12:56:35 PM) andygunn: Though it is pretty good (12:57:31 PM) andygunn: Sure. Who is the 510pen team? (12:57:52 PM) andygunn: You can put them in contact with me directly if you want (12:58:50 PM) tunabananas1: 510pen is an East Bay (SFBay) mesh network project that began in 2009 (12:59:04 PM) andygunn: Cool, good to know. (12:59:26 PM) tunabananas1: but they didn't secure funding and kinda stalled in 2011 (12:59:50 PM) andygunn: Word. That would be a problem. (01:00:14 PM) tunabananas1: since i started interning with oti/tidepools i've been helping to resuscitate it, so i'm doing a lot of the comms / project management - personally less on the technical side of things (01:00:47 PM) tunabananas1: https://510pen.org && http://sudoroom.org/wiki/Mesh (01:01:30 PM) tunabananas1: ah, i see legind is in here. he's part of the crew. o/ (01:02:00 PM) andygunn: I will check out those sites. Glad to hear there is a "new" network in the works! (01:02:33 PM) tunabananas1: yeah! mesh the planet! (01:03:52 PM) tunabananas1: and thanks for your advice. there's definitely interest in working with the commotion (01:03:54 PM) tunabananas1: firmware* (01:04:13 PM) andygunn: Excellent. Folks should hop on the Commotion Dev list if they have questions about implementation (01:04:27 PM) andygunn: Do you need the link? (01:06:05 PM) tunabananas1: https://lists.chambana.net/mailman/listinfo/commotion-dev cc legind (01:06:20 PM) andygunn: Yep, that's it. (01:06:23 PM) andygunn: Thanks! (01:07:34 PM) tunabananas1: so we are planning to do some rooftop testing soon before the weather gets too nice (01:08:08 PM) tunabananas1: but in crappy conditions what's the range of a directional ubiquiti antenna (01:08:09 PM) tunabananas1: ? (01:08:38 PM) tunabananas1: based on your experience... (01:08:39 PM) andygunn: Depends on the Antenna (01:08:51 PM) tunabananas1: DotA (01:08:58 PM) grady: lol (01:09:09 PM) andygunn: If you are using a NanoStation M2, about a mile (01:09:16 PM) andygunn: also depends on interference (01:09:21 PM) grady: I've found the range on picos goes way down in bad weather (01:09:37 PM) andygunn: Yes, omnidirectional units have much less range (01:09:44 PM) andygunn: about 1000 feet outdoors in clear weather (01:09:57 PM) andygunn: Also, pure RF range is deceptive (01:10:11 PM) andygunn: Since low signal may be fine if there is no interference (01:10:20 PM) andygunn: but in the presence of interference, your link quality will go in the crapper (01:10:32 PM) hawkinsw-laptop: is anyone on a college campus that can help me with access to jstor? (01:10:52 PM) andygunn: So for critical links over a long distance, I recommend using 5GHz equipment (01:11:05 PM) andygunn: It can bridge to the mesh via Ethernet (01:11:14 PM) andygunn: With some extra configuration (01:12:05 PM) andygunn: There is also a question of TCP ack round-trip time with long links, that I'm not sure is implemented in mesh firmware yet (01:12:14 PM) andygunn: I was going to start a thread on Commotion Dev about it (01:14:29 PM) areynold: I can almost guarantee that Ben is going to be your best bet in getting that question answered (01:14:55 PM) tunabananas1: what would the distance range be on 5ghz equipment? (01:15:04 PM) andygunn: DotA (01:15:08 PM) tunabananas1: lol (01:15:24 PM) andygunn: But for a NanoStation, again a mile or so, maybe further (01:15:39 PM) andygunn: If you have very long links there are various dishes that are made for longer distances (01:16:08 PM) andygunn: http://www.ubnt.com/airmax#nanobridgem (01:16:14 PM) andygunn: http://www.ubnt.com/airmax#airgrid (01:16:31 PM) andygunn: These and other pieces of equipment are more geared towards point-to-point setups (01:16:50 PM) andygunn: Or for receiving a more powerful signal from further away, such as in a "cell tower" style install (01:16:59 PM) andygunn: Also called Point-to-Multipoint (01:19:41 PM) grady: I sat in on a two-hour long lecture on setting up ubiquiti networks at the CTS in Tunis (01:19:56 PM) grady: I can dig up the notes and send them to you tunabananas (01:20:17 PM) tunabananas1: that'd be great, grady, thanks! i'm jenny(a)thepyre.org (01:20:50 PM) andygunn: Grady - please share that with the field and tech teams as well (01:21:03 PM) grady: sure no problem (01:21:07 PM) andygunn: Thanks (01:21:30 PM) grady: also, I know a distributor that gives pretty sweet discounts to non-profits (01:22:46 PM) andygunn: Distributor of what? Wireless equipment? (01:22:57 PM) grady: yeah, mostly ubiquiti (01:23:13 PM) andygunn: Which vendor? (01:23:20 PM) grady: streakwave (01:23:39 PM) andygunn: Yea, we don't have an account with them yet, but probably should (01:23:48 PM) tunabananas1: haha, wasn't going to mention it but yeah, equipment is pricey. we're thinking of applying for openitp funding. we're not a nonprofit, just an amorphous grassroots group atm. (01:24:46 PM) andygunn: Yep - some of the equipment is pricey, but you should see the prices for proprietary mesh equipment (01:25:21 PM) andygunn: It's hilarious: https://www.tessco.com/products/displayHierarchySkus.do?groupId=595&subgrou… [View Less]

Satellite dish antennas

by Marc Juul

I want to start doing some experiments with roof to roof wifi. I think it would be a worthwhile to get two portable satellite antennas with tripods and see what we can get out of them. With such a minor investment in equipment we will be able test whether two rooftop locations can connect to each other before we go out and buy dedicated equipment for installation. The small direct tv dishes can be had for $15 to $25 on craigslist. I found the following on craigslist for $35: *Two satellite … [View More]
