Small Business Owner ( Wifi Business )

Harry runs a small business setting up wide area wifi networks for local business improvement districts and small towns/cities. He prioritizes enterprise level service, but in the interest of making wifi accessible to the masses, he would like to use technology that allows people to continue to build off a core network. It’s important that he can access a dashboard and understand the health of the network. Also, it’s important for him that the tools are easy to learn so that local residents can become the support infrastructure as he does not have a large team to scale for support. (look at Village Telco’s sustainable entrepreneurial/small business model for local ISPs in rural areas.

Community Techie

  • wants to develop a community network
  • wants to create local apps

Tennessee lives in an urban town/city in a generic region (not Tennessee, because then her name would be quite confusing) where tensions between her government and its people have been rising. The same technology that Tennessee's government used to censor websites allowed it to monitor Internet traffic and intercept communications. Recently, as citizens have been using digital media to incite mass action and protest the government has taken to turning off the cellular and internet infrastructure when the people get particularly vocal or during events that might incite action.

Use case stories for security modeling

Private Commotion Mesh:

Since the last blackout Tennessee has started to realize that when she most needed the internet and cellular service to check on her loved ones and get news about the surrounding area it would not be available. Some of her more technically savvy friends and her decide that they will create a local network so that they can communicate securely with each other even if the other means of communication are cut.

This use case is the: Small group closed community network The focus of this network is: security and connectivity The devices used will be outdoor wireless routers that are connected to through ethernet or as Access Points or using Commotion on devices.

Open Commotion Mesh:

As people hear about Tennessee's mesh network, and have to rely on her and her friends to relay messages when communications infrastructure is out they ask to get access. The group decides to open up access to their mesh network so that other's can join. Individuals must either give the device to the group to setup to securely connect to the mesh or are given the settings file on a usb so that they can connect their device to the mesh.

This use case is the: Community Wireless Network The focus of this network is: connectivity and security

The devices used will be outdoor wireless routers that are connected to street level access points to provide connectivity.

Mesh Applications:

As more and more people within the community hear about the mesh they attempt to use it. These users find out very quickly that a local network does not let them access the services that they use on the internet to communicate to each other. So, members of the community start to put up their own services on devices directly hooked to mesh routers as well as on laptops that wirelessly connect to nearby devices.

This use case is the: Community Wireless Network The focus of this network is: applications

The devices used will be desktop and laptop computers connected to outdoor wireless routers that are connected to street level access points to provide connectivity.

Protest with network

As contention grows between the townsfolk and the government Tennessee and many of the other townsfolk chatter on twitter and facebook about how the government has gone too far. In response to calls to organize marches the government turns off the internet and cell service. Tennessee and a group of her friends move down to the town square. Using her mobile phone and Tennessee sends messages to a few of her friends who are on the mesh telling them where they are going. Looking at the local tidepools to tag the square as an event on her phone, Tennessee also notices that someone has put up an alert of a few streets already closed by the police, so she and her friends change their route.

This use case is the: Pop-up Network CONNECTED TO A Community Wireless Network The focus of this network is: connectivity, security, plausible deniability

Protest without network

Tennessee and a few of her friends travel to a nearby town to join a protest. They have carried with them a few of the battery powered mesh nodes with file sharing and chatting applications on them. They set up the devices and tell other protest members to upload their photos to the devices as they move throughout the protest. When they get within range of the community network in their town the photos will start to sync with the local photo share, distributing them throughout the town.

This use case is the: Pop-up Network The focus of this network is: connectivity, security, delay tolerance/data robustness, data redundancy
