Hey so I'm super late, but I am definitely coming (I got sucked into watching a basketball game!) I did call these folks today: http://www.hamradio.com/locations.cfm?storeid=3 I asked about non-penetrating mounts and they mentioned that they have "tripods". I know that's not really what we were thinking about, but I think it'll be worth it for me to swing by tomorrow and take a look. I'll drive, so if anyone else is interested in swinging by, let me know. Probably around 2:30 or so... On … [View More]

A survey of community network management solutions

by Mitar

Hi! Please help us fill in the spreadsheet of community network management solutions out there. We filled in those we know about, but even those only partially. So if in your network you are using some solutions for network management, please fill it in: https://goo.gl/JbD4VC As we are working on nodewatcher v3 we are trying to keep up with developments of others. We will also use this data in the paper we are writing about managing community networks. Feel free to use the data as well. If … [View More]

Google's Project Loon Gets 'Autolauncher,' Mesh Networking

by danarauz＠gmail.com

At first I thought it is good idea for people in countries/areas w/o Internet, but not long after I also thought... gosh.. we humans are being track down (by google and partners) to the end of the wold. This is horrible. Article and Video: http://www.pcmag.com/article2/0,2817,2485127,00.asp Same Video embedded in the article: https://www.youtube.com/watch?v=HOndhtfIXSY

Should I look into this?

by pansophia

Hi, April - I've been involved in the Adeline community redevelopment process in Berkeley, and I also live practically across the street from the South Berkeley library. While Max was explaining the Mesh topology today, I was wondering whether it would be possible to collaborate with local libraries to boost their wifi signal out into local communities. The first question - and the one everyone thought you would be the most expert on - is whether it would be wise to have any contact at all … [View More]

I'll bring the M5 antenna unit today to learn how to flash it.

LTE-U - Does this Affect the Future of the Mesh Idea?

by pansophia

Hi, all - I was just reading about the potential of LTE-U to "wipe out half the WiFi" spectrum on Dave Farber's IP list. I will copy the last post here since it suggests some political awareness is called for. Sorry for mentioning it if it's irrelevant. ~ Elisa ***** ... is absolutely on track writing to the list "more limited the LAA, the better." It's designed to take half of all available WiFi spectrum. (40 MHz channels by 4 telcos = 160MHz.) WiFi is too valuable to give the telcos half. … [View More] ...is wrong speculating there isn't much to be done about it. While the U.S. press hasn't picked up much, there is D.C. opposition so strong it surprised me. If WISPs and others write the FCC, this could be stopped dead. The FCC can and should develop "rules of the road" to ensure continued vitality of WiFi, now routinely delivering 300-500 megabits with LOS. Wall Street Analyst Paul de Sa thinks the important 5GHz band can and will be protected, writing this week "We are skeptical that it will be easy to persuade regulators that this is indeed the case and think LTE-U is more likely to be deployed at scale in the new 3.5GHz band rather than at 5GHz." (deSa is a former FCC Chief of Staff.) There are major filings at the FCC from Microsoft, Google, Broadcom & Michael Calabrese. Michael Ha of the FCC indicated at a conference LTE-U is so controversial everyone has an opinion. *The other big problem: Interference is likely * There has not been a single field test of LAA, which has only been tried in the company labs of supporters. A Stanford professor tells me he expects interference will show up when LAA gets out there. Several in FCC filings have indicated similar. *What can and should block the spectrum grab* Something with so many problems and so little data would normally never make it through the 3GPP Standards Committee, loaded with excellent engineers. Qualcomm, Ericsson and the giant telcos are pushing hard to get it included in the forthcoming release 13 of the LTE standards. A Qualcomm executive chairs a crucial committee at 3GPP. Mostly the committee makes sound technical decisions good for both companies and the public interest. But on issues like this, public and private interests differ. If 3GPP had strong public participation, LTE-U/LAA would at least be deferred until after substantial independent field tests. That public participation may be in sight. The U.S. and the EU have a very strong U.S. and EU commitment to "multi-stakeholderism" and open standards. Decker Anstrom, Chair of the U.S. Delegation to the major ITU World Radio Conference, and others discussed the issue at last week's State Department Advisory meeting. There's no U.S. government position yet, but our international leads, Ambassador Sepulveda and Larry Strickling, will look very foolish calling for "multi-stakeholder" at the ITU while doing nothing about the attempt to clobber WiFi being decided behind closed doors. The EU is ahead of the U.S., with "listen before talk" required. That should also be in the standard. Verizon, I'm told, is trying to block that in the United States. Good engineers are working on the problem; LTE-U/LAA standards should be deferred until we have some results. They don't belong in this years' Release 13 of LTE. The U.S. government is a member of 3GPP and could prevent a consensus on Release 13 if it contains widely questioned extensions into WiFi spectrum. Something as important as this should not be decided without vigorous public debate. The Internet Society support for U.S. State Department efforts is crucial to Ambassador Sepulveda. He almost certainly would follow the Internet Society lead if a forceful request was made. ISOC CEO Kathy Brown and policy lead Sally Wentworth speak eloquently at the ITU about the importance of public participation in governance. *The WiFi spectrum issue is much more important than anything at the ITU, which at the last big meeting (Busan Plenipot) made clear they will not challenge U.S. policy. * FCC Chairman Kennard once explained how things like this go down. "There are some people I call Black Ninjas. They work in the dark and are very, very good" Time to shine some sunlight here. (The right solution would be sensible "rules of the road" to resolve contention in unlicensed spectrum, today and in the future. The Qualcomm lab test was against against already obsolete WiFi. The WiFi folks - in an IEEE open standards process - are working at developing more effective contention schemes. Marty Cooper, who won the Marconi Award for building the first mobile cellphone, identified better contention methods as WiFi's biggest problem. Ideas on how to do this very welcome. I'll be writing more.) [View Less]

Deployment of few links between houses in Berkeley

by Mitar

Hi! This Saturday we will be deploying few links for BSC mesh network between few houses on the south side of the campus. We start at Wilde house at 10 AM. And we will work on Loth, Afro, Castro, Sherman and Davis houses. Here you have addresses and the map of all houses: http://www.bsc.coop/housing/map-directions If you are interested to help or learn, come around. Bring tools you think might be useful. :-) My phone number is 510 717-4612. Mitar -- http://mitar.tnode.com/ https://twitter.com/mitar_m
