Re: [Open Manufacturing] Home built ad hock mesh network cell phone

[m d]

I am very interested in this project, will up site for project if others are interested
is on my to-do list.

I envision a wearable computer about the size of an iphone, but up to an inch (25 mm)
deep, connection for heads up display glasses with stereo integrated cameras and microphones, usb
port and thunderbolt for peripherals, software radios for wifi, wimax, G3, G4, and other spectrum
and protocol compatibility, P2P, and VOIP capability. The device would be ruggedized and
configurable with different modular hardware options in a free and open source standard. It would be
able to run Linux or Windows, maybe even as a Mac OS X Hackintosh. additional modules for wireless,
data collection, controllers, can be stacked on top of the mainboard.

Following is a list of hardware and software already available:

laser projector for heads up or integrated projector display:
http://www.microvision.com/technology/picop.html

pico-ITX mainboard, 100mmx72mm: http://www.via.com.tw/en/initiatives/spearhead/pico-itxe/index.jsp

monitor glasses: http://www.vuzix.com/home/

mesh networking software: http://wiki.debian.org/FreedomBox
http://www.freedomboxfoundation.org/learn/

white space frequency radio: http://www.neul.com/
http://www.weightless.org/

open source cellphone: http://wiki.openmoko.org/wiki/Main_Page

cell base stations:
http://www.h-online.com/open/features/Building-a-GSM-network-with-open-source-1476745.html

It can be seen that the components are all available, just need to be integrated in a package.

No, I am talking about having each phone as a network node in a giant ever changing network based on vectors, and parity etc, using a few sockets on each phone, ie I can talk, surf web, download and support others doing the same,

I send message, it goes to carl, from carl to jim,, from jim to a router, to the net, back out a router to sally to bob,

now picture that divided into 2000 pieces and with multiple copies so I can detect the best paths for each new iteration, 

[m d]

Piratebox and librarybox are a subset of the desired capability - we're looking for peer-to-peer
everything, not just file sharing, but also communications, and even finance.

Essentially we want a virtual p2p cloud across a mesh network with enough redundancy to allow for
nodes to come and go from the network. It functions similar to a RAID drive spread out across a
network, so not every drive has to be online to access the files and nodes can sync when they connect.

It would have multiple redundant paths for messaging and communications among nodes, and would be
nice to have interconnectivity with VOIP for telephone and also internet. A software radio with
electronic tuner would let it connect to G3, G4, GSM, Wi-Fi, Wi-Max, broadcast TV whitespace
networks, bluetooth, zigbee, and use other unused frequencies as available. Multiple radios can be
added, and other interface cards as well, like data collection for scientific and field use. Any
node could act as a cell phone base station as well. It can also enable p2p micropayments and
commerce using Ripple, Open Transactions, and Bitcoin. Interoperability with Square and Paypal card
readers for POS payments is also useful.

There seems to be some interest. Any ideas on a project name, preferably a name which is descriptive
of the project, like open cell phone (yes) vs open moko (no)? I'm trying to think of something which
encompasses mobile communications, mesh and p2p networking, computing, and user configurable modular
design using open standards and software. Once we come up with a project name, I will set up the
domain name and a web site for people to access.

FreeDatNet?

as in free data network?

It does have a lot in common with Freenet.

as in infinite? 

Could this system support using a vector assignment and  possibly even a route submission to predict where nodes are/will be?

I know a line is a lot less power then a sphere, and a cone is more possible, 

some one help me to understand how cell data is not handled this way?

like 50 antennas surrounded by pockets that are "insulating" to EMF, so only signals from one set of angles hit each antenna,

Couldn't I eliminate noise all around me by knowing who is broadcasting to me and how they are moving?

could I handle multiple data streams?

[Jacob Merrill]

I know if I have a antenna receiving a steady data stream, and I spin a charged wire around the antenna at a high rate, wherever the wire blocks the signal, that is like casting a ray to triangulate a source, so if I have 3 sets of 2 on different Axis, then they could identify where a signal came from almost instantly, 

these could "track" a distant signal and the route it on in the other direction with a very directional beam,

these could be linked to digital Ham radio to create very very long links, that are messy.....

but with local cell to local cell to local wireless networks to internet to local wireless to cell node to cell node , you could already almost reach anyone....

[m d]

cell phones are omni antennas, wirless n routers have 3 antennas for MIMO for increased throughput.
I would want an external antenna interface jack with switch to disconnect the internal antenna so an
external antenna can be connected. This can be an omni or a directional antenna such as a helical or
dish. A developer might even want to come up with a phased array like Vivato. a communications card
could have multiple dipole antennas for triangulation like you suggest or use sector antennas like a
cell tower.

[m d]

cell data is handled this way at the tower - it uses directional sector antennas which cover an
angular segmented portion of 360 degrees, like 30 or 60 degrees, and also have a concentrated beam
pattern strongest parallel to the earth's surface and weakest perpendicular to the earth's surface.
Many omni's are also concentrated this way, like an 8 dB omni has a donut like toroidal beam pattern
to amplify where the signal is most likely to be used instead of radiating equally to the sky.

[m d]

could maybe do a cool logo, a mashup of infinity and the greek letter phi, ∞ and Φ, for inphinity.

I'm worried that would appear too, ahem, phallic. Maybe INFINET would be better, or something even more creative, like, InFeNeTi...

Anyway, I spent a couple minutes in Inkscape:

here's a concept, also inkscape, avoided phallic

What about Freedombox? http://freedomboxfoundation.org/learn/

Here are some existing projects http://emergentbydesign.com/2011/02/11/16-projects-initiatives-building-ad-hoc-wireless-mesh-networks/

You're looking for something called the Serval Project.

[m d]

Nice list in one place. I see the p2p DNS and gnup2p, https://gnunet.org/ , as very critical.
Freenet will work much faster if the nodes become more dense and is sort of like a virtual cloud
drive. Freedombox seems well developed, ready to use. This list is a good directory of software to
be considered for an open mobile hardware platform and compatible with existing off the shelf
hardware as well.

[Jacob Merrill]

Can some one get a component set into something like blender, and have a system to "tag" where what connects to what etc?

So anyone can buy the list of pieces, do a step by step and make a phone?

maybe a few versions for different style interfaces and costs?

potentially a hierarchy nest based on 

Os->base board->Base hardware->Base modifiers?

like android -> Raspberrry Pi-> Usb host?

 

 

[MauiMaker]

Another one to look at would be http://project-byzantium.org/

It is not a phone based rig though.

Its a linux distro designed to turn any wifi enabled system into a node/server - giving an ad hoc mesh IP net and possible internet gateways.

[m d]

The 802.11s standard looks interesting since it is adopted as a standard and already added to linux,
http://cozybit.com/our-projects/wireless-mesh-networks/o11s-mesh/ . it is included in battlemesh. i
like the byzantium setup, looks like plenty of recent work on it. it may be worthwhile to come up
with a cheap arduino or raspberry pi based node in a weatherproof enclosure with external antennas
which can run off of solar power which could be scattered about on rooftops.

Very interesting. Perhaps we should invite someone from the cozybit team
to join the discussion.

I've been looking at power consumption of arduino and 802.11n to see what size panel for a wireless
self powered unit and ballpark figures for pricing.

power, http://www.icetechusa.com/catalogue-solar_charger-907018-spec.html , sells for $20 retail on
sears site, puts out .44 watts peak power, panel is 40mm x 90 mm x 10 mm thick.

802.11n chip, http://cache.freescale.com/files/wireless_comm/doc/data_sheet/AR4100_DataSheet.pdf ,
shows max of .75 W on transmit at 3.3V

Raspberry Pi, http://www.raspberrypi.org/phpBB3/viewtopic.php?p=164893 , .75 W (A) to 1.5 W (B)

arduino, http://arduino.cc/forum/index.php/topic,5536.0.html , about .1 W
arduino table of speed vs. voltage, http://www.gammon.com.au/forum/?id=11497, 3V derates 20 mhz down
to 12 mhz

From this brief survey, it looks like an integrated 50mm x 100 mm x 25mm solar powered wireless mesh
unit with with 802.11n radios could be made in volume for under $50 with a custom board for the
electronics and injection molded packaging, after prototyping with arduino, the cell charger, and an
802.11n shield.

[Oren Beck]

I have been following this and the new posts for a while.

Some of the wild success in Open source/Crowdsourced projects is variously based on "Coherence Strategies" yet still cherishing true Meritocracy.

Sifting gold from crap is the detail most non-trivial.

ALL the other details including crap deletion fail unless there's a project coherence.  So- what schemes for coherence does this group have..if any?

[m d]

Do you have any references on coherence strategies? I did a quick search, didn't see much
explanation or definition of the term.
