Thanks Nicolas,
we did a lot of work in last two years.
We have deployed wifi network in refugee camp that rotated 4000 people
each 24h and in 4 months we served over 500,000 people with wifi. Even
getting a licence to enter a refugee camp from ministry of internal
affairs was hard enough, then we has only 72h to build and deploy
hotspots on light poles that has power only during the night. So in
two days without almost no sleep we build charging and monitoring
system with batteries under 100€ that worked from first try. And it
worked for months in harsh outdoor environment.
And on the third day we had all of our hotspots deplyed, thanks to lot
of people in our local hackerspace that helped and thanks to awesome
Nodewatcher system that enabled us to configure all devices and build
wifi mesh network in just few hours.
I hired professional mountain climber to teach me and help me take all
these devices up to 30m high poles and not die while doing it :) I
didn't want to risk any of the other guys from our hackerspace, this
was my duty to do on my own.
What I saw when working with biggest NGOs in the field that none of
them are ready for rebuilding internet infrastructure when it goes
down, and we have the technology that can be used to rebuild it much,
much faster, cheaper and the most importantly at scale!
All other solutions don't scale and are insanely much more expensive.
I have reseached this field very thoroughly and have talked with all
stake holders, like Disaster Tech Lab, communication sans frontières,
Vodafon, Unicef, Red Cross, Green peace and lots and lots of small
NGOs. And none of then have a solution that scales and is affordable.
After the refugee crisis has passed we continued working on MeshPoint.
We also build 3 generation of prototypes, did who knows how much case
designs and tested lots of boards and routers until we our current
version.
Our current version works amazingly, to he honest much better that I
expected it to work! This is mostly due to modular design which
offloads traffic to three SoC so even if one if overloaded we still
have two other ones. Also using sector antennas makes a huuuge
difference because you have spatial isolation which increases number
of users at least 3 fold. Also for conserving power we can always turn
off any board if necessary.
So we did our first controlled real world test this summer - and we
got up to 150 clients connected per radio, so that is total of 450
clients per MeshPoint! We were blown away and after we got these
results. Previously our best case predictions were up to 300 clients.
But great work that Dave Taht, Toke Høiland-Jørgensen and others did
on bufferbloat and make-wifi-faster project payed off huge for us! We
are eternally grateful for their work and all other OpenWrt and Lede
developers.
Our latest tests are deploying tethered drones to establish long range
wifi link (check out our Hackaday page for video). We are also testing
big tethered balloons filled with helium also for establishing long
range wifi links.
We are now in last stages of testing open source mppt solar charger
for LiFePO4 batteries, this will be most efficient mppt solar charger,
not most budget sensitive, but definitely most efficient. I saw that
Electra also designed mppt solar charger, and I'm interested to
compare them both if we manage to get some more people to join us.
Also we are also currently building is solar and battery powered
sensors that can be used to detect forest fires.
If your boards are available only to developers are there any plans to
release schematics under some open source licence? We have experienced
electronics people and we can at least try to build few on our own and
share our experience and even help make it better. How many layers
does your board use? Four or more?
Cheers,
Valent.

Hi Valent,
Amazing you have contacted us before us contacted you! (I have this on
my todo list for a while!)

Hi good people of Librerouter,
I'm founder of MeshPoint - humanitarian open source wifi router
(
www.meshpoint.me).
Your project is very interesting, I like the industrial design you did
for your project.
My team and I would be very interested in testing
your pcb and then
seeing if it makes sense for next version of MeshPoint. Currently we
use pcb radio boards from TP-LINK CPE210 devices.
Great!
LibreRouter will do a big difference on the user experience in
comparison to those devices, in particular because of the triple-radio
design (those are just one radio).
Are you already using LibreMesh on the CPE210?
We are also looking into making our own PCB
boards, so is makes sense
to cooperate on this.
For sure! We have already gone through the process, so we can
collaborate on the same design to make it better!
Under which open hardware licence have you
released LibreRouter?
Are pcb schematics publicly available?
Not yet, but not because of lack of interest... mainly time.
For sure will be before we make it available to the public.
Does Librerouter pcb support POE in and POE
passtrough?
Based on the spec, it supports POE and POE passthrough.

df
Is it possible to buy or borrow few prototype
boards for testing?
The amount of prototypes we manufactured was very small, and are
already commited for the development process.
Units will be available very soon.
If you register on the contact form we will let you know as soon as it
is available:
https://librerouter.org/contact/
Also would be interesting to explore collaborations.
Regards,
