Sudo Mesh is a people-powered project. That means that anyone can join the network if they're willing to contribute by [https://github.com/sudomesh/bugs/issues/new reporting bugs], improving [https://github.com/sudomesh software], fixing hardware, [https://sudoroom.org/wiki/Mesh/WalkThrough setting up a node], [https://peoplesopen.net/blog/new-node-in-the-berkeley-hills/ installing rooftop nodes], telling your friends about us, [https://peoplesopen.net/blog/build-your-own-internet-workshop/ joining for a workshop], bringing pizza to a hack session, donating  [[Mesh/Wishlist|equipment]]/[https://www.patreon.com/peoplesopennet money]/[https://blockchain.info/address/12RxU4DpLpdWcmEBn7Tj325CCXBwt5i9Hc Bitcoin], learning with us about how the internet works, or just being patient if something is broken :)


A mesh network is, in essence, free as in freedom alternative internet. Using low-cost routers (often donated or recycled) mounted on rooftops, we're currently building the backbone of the mesh throughout downtown Oakland, from West Oakland to the Fruitvale BART and beyond!
'''Interested in learning more and exploring?''' Check out our [[#Join Us|Join Us]] section. You do not need to be technically skilled to be part of this project. We need people willing to mount gear on rooftops, folks who want to do public outreach, graphic design artists, film-makers, documentarians and so much more! Show up at a monthly general meeting and get involved!


Mesh networks are awesome because they don't depend on the existing centralized Internet Service Providers to function. Though they can be connected to the Internet as we know it now, a mesh provides a decentralized means of communication with our local community. We view mesh networks as a means of reconnecting to our neighbors, supporting local businesses, and enabling grassroots community collaboration. In the event of disaster or government censorship, an active mesh network is a resilient means of communication and sharing of information.

=What does it mean?!=
Imagine if the wifi router in your home connected to the wifi routers in your neighbours' homes and they again connected to their neighbours to form a huge free wireless network spanning the city! That's exactly what a [https://en.wikipedia.org/wiki/Mesh_networking mesh network] is, or at least what it can be. Roads and telephone poles are owned by government or private interests and laying down cable is expensive, but by using wireless signals that hop from building to building we can create a community-owned and -operated, free-as-in-freedom alternative to corporate Internet Service Providers. Community wireless mesh networks are growing around the world, creating local 'internets' that support Net Neutrality and community control of critical infrastructure.

==Building a backbone of point-to-point line of sight rooftop wifi mesh nodes to bootstrap the reach of the network==
<center>
*The mesh right now has very few nodes that are directly connected (as opposed to connected over the Internet), which makes the usefulness of the mesh questionable in disaster and extreme censorship scenarios.
= Our Projects =
*We've been focusing on finding a simple and inexpensive solution for point to point rooftop nodes in order to create a far reaching backbone of high-bandwidth interconnected nodes. Currently we're testing a solution using recycled small satelitte dishes with cheap usb wifi adapters mounted and weatherproofed at the dish's point of focus. Inexpensive computers such as a raspberry pi can then, when hooked up to one or more of these nodes, connect rooftops more than a mile apart. Finding people willing to host rooftop equipment and others willing to donate unused satelitte dishes has become another way we engage with the local community.

Transmission is stil being worked out, but the current idea is that receive-hardware is cheap enough that 2 gig bootable usb sticks, tv tuners and very simple home-made antennas can be distributed both before and after a disaster, and that these will allow people to set up local stations where updates about local resources such as shelters, food and power can be accessed, while stations capable of transmitting new messages will be fewer (possibly requiring more expensive hardware) but will announce their locations such that anyone can walk to a local transmit station if they want to send a message out on the mesh.

Moving forward, we intend to expand the mesh through reaching out to grassroots organizations and local businesses, our process of designing and deploying mesh services guided by the needs and desires of existing community actors.

Sudo Mesh is a people-powered project. That means that anyone can join the network if they're willing to contribute by reporting bugs, improving software, fixing hardware, setting up a node, installing rooftop nodes, telling your friends about us, joining for a workshop, bringing pizza to a hack session, donating equipment/money/Bitcoin, learning with us about how the internet works, or just being patient if something is broken :)

Interested in learning more and exploring? Check out our Join Us section. You do not need to be technically skilled to be part of this project. We need people willing to mount gear on rooftops, folks who want to do public outreach, graphic design artists, film-makers, documentarians and so much more! Show up at a monthly general meeting and get involved!

What does it mean?!

Imagine if the wifi router in your home connected to the wifi routers in your neighbours' homes and they again connected to their neighbours to form a huge free wireless network spanning the city! That's exactly what a mesh network is, or at least what it can be. Roads and telephone poles are owned by government or private interests and laying down cable is expensive, but by using wireless signals that hop from building to building we can create a community-owned and -operated, free-as-in-freedom alternative to corporate Internet Service Providers. Community wireless mesh networks are growing around the world, creating local 'internets' that support Net Neutrality and community control of critical infrastructure.

We are spending a lot of time developing software to make it cheap and easy for anyone to be participate in cooperative communications infrastructure, regardless of technical skill.

Who are you?

sudomesh is a group of volunteers operating out of the sudo room hackerspace at the Omni Commons - a collective of collectives stewarding a large community space in Oakland, California. We develop software and assemble hardware systems to help build open community networks like the People's Open Network, a community-owned and -operated non-profit internet infrastructure in Oakland. We are all unpaid volunteers building open technology that helps to connect our neighbors, support local businesses, and enable community collaboration and cultural production. In the event of a natural disaster or state censorship, community mesh networks can be a resilient means of communication and sharing of information.
