Project Implementation Workshop Gallery Impact and sustainability Conclusion
  3. 3. Introduction      A wireless mesh network (WMN) is a multi-hop wireless network that consists of mesh clients and mesh routers. Mesh routers form the backbone of WMNs. Some of mesh routers are called gateway nodes and connected with a wired network. Each node can communicate directly with one or more peer nodes The host nodes (typically stationary) can also serve as routers to forward the clients’ traffic in a multi-hop fashion to the destination
  4. 4. Overview Node Types  Wireless routers  Gateways  Printers, servers  Stationary clients Intra-mesh Types wireless links Mobile clients  Link 4 Stationary client access Mobile client access Internet access links
  5. 5. Why WMNs?      easy deployment greater reliability self-configuration self-healing, and scalability. the nodes in the network are able to establish and maintain mesh connectivity automatically
  6. 6. Applications of WMNs        WLAN hotspot multi-hopping citywide surveillance systems wireless sensor networks (WSNs) broadband home and office Indoor networking intelligent transport system networks community and neighbour networking micro base station backhaul and many others
  7. 7. Project Target    Innovation on access provision E-Development Workshop and training for students, local technicians and staff members in some aspects of the setup, installation and maintenance of the SECN
  8. 8. Sponsors      AFRINIC/FIRE (Major sponsor) University of Ilorin, Nigeria Cape Peninsula University of Technology, South Africa Asmic Computers VT community members (Hackers, South Africa)

The team      Nasir Faruk (Dept of TCS,University of Ilorin) Olayiwola Bello (Dept ICS,University of Ilorin) Dr. Michael Adeyeye (Cape Peninsula University of Technology, South Africa, Asmic Computers) Thomas Gone, Steve Song, Antoine Van Gelder and the VT community members (Hackers, South Africa) Undergraduate students (TCS dept University of Ilorin)
  10. 10. Main Mission of AFRINIC    To serve the African community by providing professional and efficient management of Internet number resources Supporting Internet technology usage and development, Promoting a participative and multistakeholder approach to Internet selfgovernance.
  11. 11. What is FIRE?     The Fund for Internet Research and Education (FIRE) is an initiative of AFRINIC, the regional Internet registry for Africa In existence since 2007 Aims to encourage innovation and find creative, accessible and acceptable solutions to Africa’s ICT challenges. Support activities promoting Internet development in the African Region, with particular emphasis on the role of the Internet in social and economic development in the
  12. 12. FIRE GRANTS A Grants programme aimed at stimulating creative solutions to ICT development needs in the Africa Region Small grants allocated to new initiatives: looking for seed funding for research or implementation looking to scale up, expand coverage or develop new components Implementation period: 6 to 12 months Grant: USD 10,000 Application period for 2014 Grants closed on November, 30 - 2013

  14. 14. Why ?       There are over 35,000 students and 5000s of staff (academic and non- academic). Unilorin provide for studies, training research and development of techniques. Reliability and availability of the existing networks. The use of cellular phones for voice communication amongst Staff and students. No infrastructure for the legacy Plain Old Telephone System Recurrent cost.
  15. 15. Project Implementation     The network is made up of Mesh Potatoes (MP). Each MP features a wireless transceiver, telephone and RJ45 interfaces as well as industry standard PBX controllers in a robust simple weatherproof package. The telephone interface provides voice (telephony) services with the use of traditional analog telephone boxes, while the RJ45 interface provides connection to the corporate local area network (LAN) for data and computer based services. The wireless interface provides support for WiFi enabled devices such as laptop computers, tablets and mid-to-high end mobile phones. Multiple MPs are setup to form a resilient mesh network

As awareness and uptake into the programme increases, it is hoped that participants will be levied to sustain the continuous spread of the knowledge and latest developments in related areas.
  39. 39. Further work      Connecting MPs to the internet grid Planning a fully mesh communication network based on extensive use of Session Initiation Protocol (SIP) clients (e.g. Elastix or Trixbox) and closely following any new developments of the Firefox OS / Firefox phone as we presume this will be dominant technologies in the future. Implementation of PSTN/GSM gateway & the billing system (software purchase, application development and Integration) designed by Ernesto Gomez Tagle G (Violetta Platar) and Abdel Wahid Sabre Ousman (Ben Sabre Fils) in South Africa. so that calls can be made from the facility to mobile stations (GSM) and other public switched telephone networks outside the University. Software Development and installation of Automatic call logs which would provide information on the frequency of use of the telephones Deploying TV white space solution for last mile connectivity
  40. 40. Other case studies  Nyandeni, South Africa The Nyandeni telco was initiated with the support of the University of the Western Cape which has provided the initial funding to acquire the hardware and the training for its installation. It is now operated and maintained by the local community.  Ibadan, Nigeria Michael Adeyeye has been a member of the Village Telco community since its earliest days. Working through his own company, Asmicom, Michael partnered with colleagues in Ibadan to set up the Ibadan Wireless User Group.  Fusagasugá, Colombia Jorge Gomez is building a Village Telco in the hills around Fusagasugá where phone and Internet coverage is not available.  Orocovis, Puerto Rico Jose Soto is the President of CoquiTel, a small WISP whose goal to provide equal access to Internet and phone service to underserved areas of Puerto Rico.
  41. 41. Case studies cont…  Kranshoek, South Africa Wayne Abroue has lived in Kranshoek, 15km outside of Plettenberg bay in South Africa for the last 20 yrs. Kranshoek is a Griqua community. Through the wireless mesh project, Wayne’s goal is to transfer my many technical years of experience to the young generation.  Bo-kaap, Cape Town, South Africa One of the first pilot sites for Village Telco was the community of Bo-kaap in Cape Town. We chose Bo-kaap partly because of proximity but more importantly because the Bo-kaap community is well known for the strength of the community ties that bind it together. Village Telcos are most likely to thrive where people have already have strong reasons to communicate with each other locally.  Piracanga, Bahia, Brazil When Mike Jensen moved to an EcoVillage on the north-eastern coast of Brazil, he brought Village Telco with him. He has since expanded access into the local town through a WiFi hotspot and cybercafe.
