== User Experience ==
== Software ==


The node presents a uniform interface across client devices using HTTP(S) – a collection of stylesheets allow the interface to adapt successfully to a wide array of different screen resolutions and input methods. You interact with your node by opening a browser – any browser – and navigating to your node’s address. That address can be a global name such as a user-owned DNS entry, or a third-party subdomain such as username.fnf.tel, or, from the same local network, a local address, such as ‘https://mynode’. Alternatively, the node can be accessed from its unique IPv6 address.
Leading options for a FreedomNode distribution/firmware are:


Navigating to the address of a node prompts the user to authenticate. This is done using the F-Pass (F-Pass == [[FreedomTunnel]]?)system. F-Pass is the key to trust and addressing on the Free Network – tying together x.509, PGP, IPv6, and secure, one time passwords.
'''Genode plus Debian:''' For true fault isolation and tolerance, nodes could run [http://genode.org/ Genode], a novel nested operating system architecture (GPL-licensed). Then on top of that, a lightweight debian install would be used to ensure long-term package support and stability.


Once authenticated, the user is presented with a main menu that provides access to all of the essential functions of the node. Icons exist for Blogging, Microblogging, Planning (like plans.txt on Unix or GrinnellPlans), Mail, and an A/V Center (photos, music, video, and files). An additional icon leads to a list of contacts, with a final icon leading to system settings.
'''OpenWrt:''' a linux-based firmware mostly used on low-resource routers. Has a package system and strong community, many mesh protocols run on this platform.


Users can be organized into aspects, with a ‘Neighbor’ aspect generated automatically for those with whom you can communicate without need of an Internet Service Provider. From the contacts page, a user can access the blog, microblog, plan, or shared media of another user. Users have precise control over who can access each piece of media on their node. Sharing is encrypted by default, anonymized when desired, and opportunistically peer-to-peer – that means that we all cooperate to move each others’ messages, when it is possible, rather than paying a professional bit-mover
'''pfSense:''' a BSD-based firmware mostly used on medium-resource firewalls and routers. Has a package system and strong developers.

'''Byzantium Project:''' an integrated foundation for mesh communications. Their routing scheme is based on the babel protocol


For true fault isolation and tolerance, nodes could run [http://genode.org/ Genode], a novel nested operating system architecture (GPL-licensed). Then on top of that, a lightweight debian install would be used to ensure long-term package support and stability. The user-facing services run on top of Debian, powered by a collection of existing open-source daemons and tools. These services would benefit from tight integration of a unified interface and a unified authentication and identity management system.
'''Commotion'''


In the short term, and on cheaper hardware, nodes could also just run OpenWrt or pfSense firmware on the bare metal with mesh services on top of that.
'''Quagga''' (with Babel)


The Byzantium Project has built a solid foundation for mesh communications – their routing scheme (based on the babel protocol) will be integrated with nodal services so that local traffic never has to leave the neighborhood network.  
The neighborhood-scale mesh network could be one of BATMAN, BATMAN-adv, OLSR, Babel, etc.

The FreedomNode is a wireless router which acts as a node in the "neighborhood-scale" mesh network and as a downlink to the owner's LAN.

The scope of the FreedomNode will overlap with the FreedomBox in some situations, in which case some hardware might be able to fill both roles.

Software

Leading options for a FreedomNode distribution/firmware are:

Genode plus Debian: For true fault isolation and tolerance, nodes could run Genode, a novel nested operating system architecture (GPL-licensed). Then on top of that, a lightweight debian install would be used to ensure long-term package support and stability.

OpenWrt: a linux-based firmware mostly used on low-resource routers. Has a package system and strong community, many mesh protocols run on this platform.

pfSense: a BSD-based firmware mostly used on medium-resource firewalls and routers. Has a package system and strong developers.

Byzantium Project: an integrated foundation for mesh communications. Their routing scheme is based on the babel protocol

Commotion

Quagga (with Babel)

The neighborhood-scale mesh network could be one of BATMAN, BATMAN-adv, OLSR, Babel, etc.

Hardware

At the core of a full-featured FreedomNode is a small-form computer, designed to run continuously for years on end. The computer’s onboard capabilities can be expanded with USB mass storage, and miniPCI radio modules.

The following devices (available today) could fill the FreedomNode's basic networking roles until "full-featured" hardware becomes available or is implemented.

ARC Wireless FreeStation

$70, 8MB flash, 32MB RAM, Atheros chipset. Has an 2x2 MIMO 802.11n radio and panel antenna (available with 2.4GHz or 5GHz) plus a secondary 2.4GHz local access point with omni antenna. Runs OpenWrt. Dual Ethernet (PoE) and dual USB.

Ubiquity RouterStation Pro

This device is End-of-Life and no longer in production

Reliable bare-board router. Does not come with wireless radios by default, has 3x (!) miniPCI slots (not PCIe). 128MB RAM, runs OpenWRT, Atheros chipset, 3x gigabit ethernet LAN ports, 1x ethernet WAN. Retailed for $80 (without radios).

TP-Link TL-MR3020

Unclear if this would be an acceptable mesh node

Very small low power travel hotspot. Designed to share 3G uplink from a USB dongle. 400MHz Atheros AR7240, 802.11b/g/n, 4MB Flash, 32MB RAM, 1x ethernet port, 1x USB host port, powered by miniUSB port. Multiple almost-identical versions of this device exist. $40 (from amazon).

TP-Link TL-WR703N

Not to be confused with the TL-WR702N, which has insufficient Flash and RAM for most firmware

Unclear if this would be an acceptable mesh node

Very small USB-powered travel router, intended to be used as WiFi hotspot for multiple devices and/or sharing a 3G USB dongle's internet connection. Not yet FCC approved for the US and thus not yet as readily available as the cheaper 702 model? Price around $30 (overseas?)

32MB RAM, 4MB Flash, 1x USB 2.0 Host port, 1x USB device port (for power), 1x Ethernet port, Atheros AR9331 chipset.
