Timeplan

The timeplan is draft level and will be adjusted to people's ability to join for limited periods.

The first day will be dedicated to the organizational layer,

introducing the various projects and teams, discussing the business models, identifying overlap of work agendas as well as the main challenges each of the projects are seeing.

The second day will move down to detail level, moving from business and organizational models to technology requirements/specifications.

The third day

Business models

Introduction: Sebastian

Business models may be classified according to a number of different dimensions -

e.g. financial/economic layer, tech/network topology layer, applications layer, social layer, -

Based on the experience of the participants and projects, business models should be reviewed with the goal of reaching a downselection of models that should be implemented/supported in the first iteration of the WISPiab project.

Classical examples:

• Voice services - The Village Telco
• "Line sharing" - sharing internet access between organizations
• Telecentre / Internet Cafe
• Campus / School network

The goal is to go through all our relevant models, to classify them on all layers,

and to identify the technology implications (such that technology follows business models, and not vice versa), producing a clear results list.

Cooperations and Resources

There is significant overlap between projects on the technology layer. All projects are subscribing to free software models (GPL / CC, etc).

We are operating against a backdrop of

• challenged (human) resource situation
• brain drain / skills exodus
• wanting to build local (i.e. african? ... southern african? .... south african?) capacity

Cooperation between projects seems appropriate and possible.

The goal is to conclude this meeting with a clear picture of modes of cooperation.

Advisory Group

We wish to form an advisory group / peer group, including partly the invitees of this meeting, but not limited to these.

Day 2 - Tuesday, June 3

Morning

Technical Requirements / Specifications - detail level

Examples of concrete detail issues:

• Authentication - where and how
• Billing in mesh networks
• VoIP in mesh networks

The goal of this session is to fill the matrix of

technology requirements x project/business model

and then check this matrix against the various existing hardware/software platforms.

Hardware platforms aspects

A number of different hardware/software platforms are fulfilling subsets of our requirements.

The available platforms need to be discussed and evaluated, towards a decision on what to choose.

The platforms that our projects are currently working with are:

• Linksys WRT54, with firmwares OpenWRT, DD-WRT, Freifunk, CoovaAP, and similar
• Open-Mesh, Accton - with Open Mesh Firmware (new firmware anoounced for summer 2008, with: RO.B.IN, orangemesh, COOVA, etc)
• Inveneo platform
• Ubiquti NS, PS
• Meraka Bokkie routers
• pls add!

Hands-on work

Part of this session will be practical experiments with the platforms - if appropriate, in breakout sessions.

Afternoon

Productification / Dissemination / Rollout strategies

• Strategies for the productification of software packages
  • Sourceforge platform plans (Steve?)
  • Ubuntu / UCK (Sebastian, Mark, Elektra)
• Rollout capacity

Hands-on work

Part of this session will be practical experiments with the platforms - if appropriate, in breakout sessions.

Day 3 - Wednesday, June 4

Morning

Ndlovu Medical Center

Status and Agenda of network at Ndlovu Medical Center

• How can the various projects benefit Ndlovu Medical Center?

Status, gaps and planning of implementations

• WISPiab status and work plan
• Dabba / Village Telco work sprint, June 16-20
  • prepare and support that workshop

Hands-on work

Part of this session will be practical experiments with the platforms - if appropriate, in breakout sessions.

Afternoon

Conclusions & Next steps

• Dabba Worksprint
• WISPiab work plan
• Digital Doorway work
• Wireless Africa, June meeting

etc

Business Models

Discussion of business models that have informed the specifications, and a checkback whether we feel that the current specifications actually accomodate all these models.

The template on top suggests dimensions / criteria from which to look at the various models.

Henry introduces:

• Status of mesh: operational, but currently disconnected (concerns about lightning)
• Use of uplink: Browsing (for community users), sync with data center (Johannesburg)
• Status of uplink: promised by Telkom, but not delivered yet

How to get started with a community mesh?

• Donated PCs - 25 pcs
  • Give to local entrepreneur types
• Computer school as entry point

• Create a starter kit
  • for existing PCs (there is some! mostly free windows)
  • preconfigured
  • low cost
  • probably of the type: Linksys WRT, open-mesh/accton

Financing model

• Some contribution from user: Prepaid - low cost

What is interesting for people?

• music!!! open music server locally?
• free books? educational material
• free local calls
• a free wikipedia / digital doorway

Income from other sources (not the users):

• advertisements

To do / upcoming:

• call for a brainstorm meeting within the community

• June 9, meeting with provincial directory

• June 24: excursion to Ndlovu? participants of Wireless Africa meeting, Meraka people, Tom, Elektra

A word on the punishment for every watt

Elektra, conservative estimate:

To power a 5 Watt device reliably, install a 80 Watt solar panel.

This means: 16 Watt solar panel per 1 Watt installed.

At about USD 5 per solar panel watt (current rough guess for market price), we have:

USD 80 in solar panel per 1 Watt installed.

Even when demanding less margin from the solar power system (i.e. less solar panels per consumer), the fine for every Watt installed is heavy.

Next steps

• Examine the Ubiquiti - Lead: Elektra
  • flash OpenWRT
  • Examine the SDK

• Procurement - Lead: Kobus/Ajay
  • ??? x Inveneo small server

• Examine the Inveneo Hub Linux (IHL)

• Software development
  • Meraka - Priority: the set of Coova (alternative: WifiDog) / FreeRadius / phpMyPrepaid (alternative: ISPBill) / Nagios
  • Inveneo - Priority: Server squid/cache, proxy, asterisk, Webmin/ISPConfig
