WSFII and Village Telco synergy

Many of our listmembers also lurk, and post, and contribute towards development, on the Village Telco project (VoIP in a mesh box - originally only the Mesh Potato, now that and more).

Just recently, from South America, an interesting question was posted, one I feel really belongs more on this list, where people have far more experience of this kind of thing. I do hope it will provoke both discussion and active contribution to this concept - perhaps spawn a new project even?

Hi Carlos,
I think you have two problems to solve for designing the mesh. One is the distance between locations as well Gillet said, you need repeater stations similar to the "NanoStation loco2" to join the links.
The second problem is the determination of the need for bandwidth (typical problem of traffic engineering) it is essential when you have many users. To have a facility that works well, that assure users can be navigated without unnecessary delay, you will need several distributed WAN links. That is the starting point and will depend on local conditions, as well as existing telecommunications facilities.

I think Carlos may benefit from discussions at wsfii, many of whose members are active here, but the objectives are different - parallel, but not the same focus. With your permission, I am copying this exchange there, and maybe a separate dialogue would be useful.

Hi Carlos
I may be misunderstanding the picture, but it looks like you have some fairly long links there.
The effective link distance for an MP is around 1km, so I expect that you would have to use specific long range devices for these links eg the Ubiquity NanoBridge type equipment.
The MP and TP devices would form smaller local cells at the ends of these longer links.
Or am I misunderstanding?

Terry

Dear Terry
Thanks for your answer. I am very impress with the work all of you are developing. 

As I said in my last email, in several countries many rural municipalities have a few docens of schools. In the picture (attached with this email), you can see 30 schools that could be mesh with MP01 (we used MP01 parameters to run radiomobile simulation). The town is one of more than a docen towns located bellow a tropical volcanic complex (two volcanos and several mountains).  The picture describes an area of 12km2. Meshing 12-15 towns with 200-250 small schools will cover an area of 50-60 km2.

I see many possibilities in this scenario.
Kind wishes,
Carlos

Hi Carlos
I think that MP01 running SECN firmware would go close to meeting the needs you have described. However it does include a telephony subsystem and is built in a ruggedised outdoor housing, both of which add to the cost which may be a burden if you can  not utilise those facilities fully.
We are currently working on porting the SECN firmware to low cost commodity devices such as the TPLink WR703N which sells for $20 retail or $25 in mains powered form.
Our idea is to be able to be able to build a mesh based on a combination of specialised devices such as the MP01 and commodity devices such as the 703.
Telephony is supported through plain phones on the MP01 and through softphones eg on mobile devices such as Android cell phones or tablets, or Apple devices.
We also support locally stored web content stored on usb devices attached to the 703 unit for example. This allows a network to operate standalone or with reduced internet access.
It is also possible to  use one or more nodes as gateways to connect the mesh to an uplink connecting to the wider internet or a private network backbone.
Our approach is to use low maintenance, low power solid state devices for maximum reliability in the field.
With this approach it should be quite easy to assemble an economical wireless based network for the type of school situation you have outlined.
Linking the schools together in a cluster would require more specialised long range equipment such as provided by Ubiquity. This is no real problem technically and has been done in a number of Village Telco implementations.
The SECN firmware provides simple voice and web based interfaces to allow set up in the  field by users with limited technical training and facilities.

Terry

What wifi router to use

Hi

Friends , hope all is well you side !

needed some advice of which wi-fi router would be a good one to buy (in India) -  with the following specs
- one in which the firmware can be upgraded (am thinking to the openwrt firmware - unless there is a better firmware for a community mesh network)
- possibility to powered by solar

This wifi router would be test router , initially just for a home network and later on this would be scaled up to more nodes.

a friend suggested the Linksys WRT54gh - retailing for Rs 2000 (in India). But this link http://wiki.openwrt.org/toh/start#linksys does not show this specific model

so look forward to you advice

Re: What wifi router to use

Hi Ramnarayan,

A number of people in the Village Telco community have been using the
TP-Link WR703 and have had good success using OpenWRT and batman-adv.

Dear Steve

Thanks for the link, it looks exciting and also it lead to the Mesh Potato, which seems exactly what we want to have here

Re: What wifi router to use

Hello Steve,

    I just bought a model like that, but I was aware that it supports exclusively 802.11n. It seems that the current MP version is only b/g and thus would not be inter-operable with it, correct?

    I also bought this model (WR710N) -  http://www.volumerates.com/product/tp-link-wr710n-mini-pocketable-11n-150-mbps-wireless-broadband-router-with-dual-lan-connectors-101283, since it supports 802.11b/g/n and (possiblity?) is flash-able to run openwrt / BATMAN?

    I cant wait to put my hands on them :)

best regards,

The WR703 does support 802.11bg.  Terry Gillett has now got a working
firmware for it that interoperates with the Mesh Potato.  See this
thread for the entire saga

Unless I'm mistaken, Terry Gillett has these units working too.
