Hello,
I don't think that anyone has attempted this. Recent versions of Serval
use VoMP as the calling protocol instead of SIP. There is a VoMP to SIP
gateway, but you would need to compile that into the MPs for it to work so
that there is a bridge between the Mesh Potato world and the Serval
protocol world.
Paul.

So would that be VOMP on all the VT devices, or just the "SIP master"?

Hello,
For a wifi themed event taking place in the Netherlands (Maastricht) coming
April I am looking for someone who has done a reasonable sized project
involving Village Telco software (and hardware) who would be willing to
give a presentation.
The event is covering different areas of the wifi industry, will have a
strong tech focus and we aside from the usual vendors we also want to make
space for talks/workshops on Open Source wifi projects.
I've used Mesh Potatos before so know a good bit about them but am looking
for someone else willing to talk about their project experiences etc.
The event website has just gone up and we're adding new speakers as we go
along but feel free to have a look: www.wifivaganza.com
Anyone interested in speaking/presenting please contact me directly please.
Regards, Evert Bopp.

In the past week or so there was a posting about using Ubiquiti devices
as range extenders for MPs and a recommendation to just use the standard
Ubiquiti firmware as long as the Ubiquiti hardware is only used for
point to point range extension, not as a participant within the mesh. Is
that correct?
For example, at a recent exercise we used a mix of MP-1s (updated with
SECN) and MP-2 phones at a base camp. The MP-2s were inside metal
trailers and buildings and the range was compromised. We couldn't place
the MP-2s outside for a number of reasons. If we had a couple of
Nanostations up on outside poles to bridge the longest gap, all would
have been well.

Steve

Hi Steve
That is correct, can be setup as layer 2 bridges. So theoretically you should even be able to push the mesh over the link, if you have batman running on your lan side of the mp's also.
Without that the link should just work for ip phoning etc..

This is correct.
It is also possible for a (very) large project to use nanostations +
mikrotik routerboards and do bgp routing to transparantly connect
multiple secn mesh's with full routing.
Inside a mesh the data troughput is max 50% of hw capacity. In a bgp
routed network the troughput is 100%.
A bgp routed network could completely replace a mesh in a massive
project. Altough you would lose the "easy setup and deployment" and
require lots of advanced planning.
The combination of mikrotik routers and ubiquity gear in bridge mode
will allow you to setup a very efficient "interconnect" to multiple secn
meshes when using 5Ghz bridges.
We have this bgp setup in Belgium where we cover an area of roughly 200
KM X 50 KM with over 100 backbone nodes. The longest single hop we have
is +/- 50 KM (Antwerp datacenter to Brussels datacenter) connecting 2 of
5 internet gateways.
Cheers,
Michel

In that scenario, how would you have connected the Nanostations to the MP2 mesh?
Regards,
Steve
There are many ways to approach this sort of situation, where the mesh nodes are spread over a wide area. The best approach (ie simplest, most economical) for the situation will depend largely on how big an area you are trying to cover, and the layout of nodes around the terrain.
Some example possibilities, in order of increasing complexity...
1. One of the simplest approaches is just to have one mesh node that can be 'seen' by all the nodes in the mesh e.g. the node is mounted in an elevated position such as on a pole. For this, you will probably need a node that is in an outdoor enclosure. You could use a standard MP2 in a box, or you could use a Ubiquity device flashed with the mesh firmware eg SECN.
2. If one such node is not enough to provide a good signal to all the mesh nodes, then you might use two such nodes. This would be appropriate where there are two clusters of nodes that are separated by a reasonable distance such that the individual mesh nodes in one cluster can't get a signal from those in the other cluster. As long as the two elevated mesh nodes can get a good signal from each other, then all nodes on the mesh will be connected.
3. If the two elevated mesh nodes can not get a good signal from each other (e.g. they are too far apart), then you will need to connect them by some other method. This is where the long haul capability of the standard Ubiquity devices can be used.
You need to set up a long haul link between the two elevated mesh nodes. A simple way to do this is to use two additional Ubiquity devices that can connect over the required distance, mounted with the elevated mesh nodes.
Once the Ubiquity long haul link is established, then the Ubiquity devices can be connected to the mesh nodes via Ethernet cable. This will then connect the two clusters of mesh nodes.
It does not really matter how the long haul link is established, as long as it provides a transparent connection end to end then it can be used to connect the two mesh clusters. As Wayne has mentioned, you can run the link at either Layer 2 or Layer 3 depending on your specific requirements.
4. Keep in mind with these arrangements that any link joining two mesh clusters represents a single point of failure. If you are setting up a network for long term use, you may consider providing some level of redundancy.
5. On a different tack, if a mesh node is inside a metal trailer, then obviously it is going to have difficulty in getting a good signal from other nodes. You might improve this by using MPs that are fitted with external antennas that you can mount external to the trailer.
Alternatively, you could use a standard MP2/MP2-Phone and fit a USB wifi dongle as a second radio to run the mesh wifi interface.
The SECN-Duo firmware is intended for this purpose and allows you to 'plug-and-play' radios and antennas, and to mount the second radio remotely from the MP2 eg outdoors. For details, see the wiki page:
USB wifi devices are generally low cost and available with a range of antennas, such as directional panel antennas, that can provide a useful improvement in signal, and some are in housings intended for outdoor use.
By using these alternative USB based radio/antenna combinations, you may be able to cover the required area just with mesh nodes without having to resort to specialised long haul links.
I hope these ideas are helpful and I am very interested to hear how others have tackled these real world issues.

Terry

Would it be possible to configure the mesh node long haul network using bgp routing, therefore 100% throughput on the backhaul, with individual single or dual nodes as needed meshed with users at the edge? The complexity of the long distance network would then be manageable from one place, probably, while the end users get along using the relatively simple mesh, needing less technical/expert assistance in the long run. This would hypothetically be a natural extension of suggestion #4.

I have no experience with using BGP so I can't really comment on how well this might work.
The quagga package is available to install in OpenWrt so I guess it would be feasible to try it out.To view this discussion on the web visit https://groups.google.com/d/msgid/village-telco-dev/CACRkhvpPfOqASviSW%3DkcRwgGEQurmuvReC%3D%3DENGPat9x8vLzhQ%40mail.gmail.com.

I think the Guifi.net folk use BGP for the backbone of their network which is well over 20K nodes at this point and a combination of fibre and mesh wireless but I have a hard time seeing it as very practical for small networks.

Indeed, BGP is used by large networks like guifi.net, Athens
wireless, Wireless Belgium, ......
BGP is not plug and play and poses quite a learning curve to setup.
The benefit of using it is it alows to reach full speed of the link technology that is deployed.
In the context of a village telco deployment BGP can be used to create a high speed backbone to interconnect mesh networks.

The model supports the notion of growth of a collaborative self sustaining network, but growth need not be a necessary ingredient. Possibly a new kind of sustainable network idea, ie, an expert backbone service for discontiguous local networks that may free them from the local monopolies or oligopolies that control the external interconnects, is needed.
It will function within the overall concept for which Village Telco came about, but I am not sure how to attract the expert knowledge here, until there is a test case for such a deployment.
