“E-Access for All” Comparative study of “first mile” and “first inch” technology in different low density contexts. Government of Karnataka and UNDESA, Bangalore 8-9 February 2007 Chris Morris African Advanced Institute for Information & Communications Technology (AAIICT) Overview • • • • • • • • Access in South Africa The Challenge The FMFI Philosophy FMFI Projects – Overview FMFI Projects – Technical Technical Development Challenges and Next Steps Conclusions Access to ICTs in South Africa • • • • South African market $ 10 billion Unequal distribution “Africa least wired region in the world” Fixed lines @ 25 per 100 households • Benchmark 50 per 100 lower-middle income households internationally • 25 m cell phones • Poor broadband access • ITU 2003 comparative study for e-commerce No Access? • A regulatory environment that : • • • • Restricts competition Caps technology Isolates communities Restricts community economic development • Regulatory policy – African Digital Divide The Challenge • How can rural communities overcome failures in regulatory policy by implementing innovative, low-cost connectivity solutions in order to promote sustainable development? • “…we have to ensure that as many of our people as possible master modern technologies and integrate them in their social activities, including education, delivery of services and economic activity. This relates in particular to communication and information technology.” (President Thabo Mbeki, SA National R&D Strategy, January 2002) • “The AAllCT will undertake world-class, needs-based and applied research in ICTs, leading to development and innovation-for thebenefit-of the economy, to advance the quality of life of all South Africans and advancement of the region as a whole …” The “first mile first inch” Philosophy • A different mindset – put end-user first, empower communities, create new demand for ICTs • The Indonesian example – Dr Onno Purbo • Vision • “To have social and technical innovation on service delivery models in different contexts of communities with low-density telecommunications.” Definitions: “first mile & first inch” Upstream\Backbone First Mile Satellite ISP ISP PSTN Internet Local Provider Internet ISP ISP Wireless Link Wired Link First Inch FMFI Projects & Partners Angonet (Huambo) UCM (Pemba) Angola Mozambique Wireless (Harare) ISPU (Quelimane) Zimbabwe SchoolNet Mozambique (Inhambane) Power Line Comms (Rooiwal) MICTI (Maputo) CSIR HLT (Openphone) South Africa Translate.org (HTML Pub) Wireless Mesh (Peebles Valley) CSIR Telehealth (Eastern Cape) UWC MuTi (Eastern Cape) FMFI Projects • Assist the repatriation of displaced families and communities through the use of internet over VSAT and WiFi networks in war torn Huambo in Angola • Equip tele-centres with voice mail boxes for voice and or pictures of loved ones for improving sustainability of telecentres in Maputo • Connect rural teachers in Pemba and Chiure districts in Cabo Delgado Province to their tutors at the Catholic University of Mozambique, Pemba • Improve communication between doctors, health workers and clinic sisters in the Eastern Cape and Mpumalanga provinces of South Africa • Improve education in remote parts of Namibia by providing internet access to schools using WiFi technologies, refurbished PCs and open source software • Use Human Language Technologies to create an authoring environment for a telephone-based information systems at tele-centres (Open Phone). Objectives • Changed behaviour in the use of ICTs – how the use of ICTs has changed community life • Cost and benefits of solutions – to quantify what is meant by low cost connectivity • Scalability and replicability of technologies – the viability of rolling out the solution • Influence on policy and regulation – demonstration of project benefits to the regulator Overview • • • • • • • • Access in South Africa The Challenge The FMFI Philosophy FMFI Projects – Overview FMFI Projects – Technical Technical Development Challenges and Next Steps Conclusions Tsilitwa project: Eastern Cape, SA Rural Health Network Concept VSAT Bi-directional Links Share ed ar Sh W B d BW Tsilitwa Clinic Nessie Knight Hospital Cluster Base Government Health Link DoH / UNITRA / Other Kalankomo Clinic Clinic III Clinic II Via Wireless (802.11b/g) or other First Mile Technology Health Centre Cluster Base Clinic I Clinic III Clinic II Tsilitwa Wireless Network Kalankomo Clinic Tsilitwa Clinic Nessie Knight Hospital Guru Clinic Mahlungulu Clinic Applications Tele-Consultation Send site Receive site Tele-dermatology Wireless Network Types • “Hub-and-spoke” wireless systems connect users with line-of-sight antennas to a centrally-located broadcast tower. Clients who cannot see the hub from their building cannot join the network • Mesh wireless systems offer multiple points of connection to the network and no central tower. Mesh users can bypass obstacles like hills and trees by using different signal paths Mesh Networks • Self-forming, self-healing and self-routing • No large masts typical of a hub and spoke architecture • Adding subscribers increases coverage and robustness • Omni directional antennas simplify installation, maintenance and reconfiguration Mpumalanga Mesh Network, Peables Valley, White River First stage rollout Second stage rollout WIFI NODE SCHOOL 2 WIFI NODE PUBLIC CLINIC Third stage rollout WIFI NODE SCHOOL - JERUSALEM WIFI NODE SCHOOL 1 HUB SCHOOL LAB SERVER WIFI NODE FARM 2 LAB PC1 WIFI NODE FARM 3 LAB PC 2 LAB PC 3 WIFI NODE FARM 1 US AID LAB PC X WiFi NODE ACTS Internet WiFi NODE PETRA Sentech VSAT WIFI NODE HOSPICE Hub ACTS CLINIC Hub Mesh Server PC1 PC1 PC2 PC2 What is PLC? • • Uses existing optical fibre and copper wire to provide telephone and internet connections to homes and businesses Makes it possible to communicate through the power outlets in each room of the home or business ACCESS BPL High Voltage Medium Voltage Low Voltage ~ 1kVolts to 40 kVolts ~ MVolts Coupler ~ 120/240 Volts Coupler LV Distribution Transformer Power Generation Plant Substation Backhaul Point (Gateway) Internet Internet BPL signals are extracted here & converted into/from traditional communication packets for appropriate communication direction Aggregation Point In some Access implementations, these physical links are replaced by wireless links Power Line Interface Device Located In Home Technical Development OpenPhone • OpenPhone is an open source telephony based information dissemination environment. • Address the significant African need related to the information empowerment of its people • Human language technologies • HCI research • Social research • Open source principles OpenPhone Authoring tool Application Designer Runtime Environment Recoded prompts End user input Workflow component Telephony infrastructure Information User Solution – Authoring tool • • • • • An information provider can design an information dissemination application using the authoring tool. The prompts for the various phases will be recorded. The designer will be guided by the use of templates Information users will access the designed solution by phoning a (toll-free/sponsored) number. Will listen to the voice prompts and interact with the system entering requested key presses (DTMF/touchtone). Application Designer Mobile Technology • • • • • Mobile devices: GSM phones, multimedia/smart phones, Internet tablets Wireless networks: GSM, 3G, WLAN Voice, speech and language technologies: speech interfaces, audio information systems etc. Social software: Mediawiki, blogs, Knowledge Building tools. Wikipedia: The Free Encyclopaedia. Pilot 1: Cornwall Hill College • The MobilEd platform was used to assist in a lesson re HIV/AIDS • Students could get information via the MobilEd server and • Contribute information back by adding voice clips with their contributions to existing articles. Pilot 1: Cornwall Hill College Stage 1 • A mobile audio wikipedia can be accessed by sending an SMS with a key word. • The service calls back and plays the information, making use of text to speech conversion. Pilot 1: Cornwall Hill College Stage 2 • Learners could make their own audio castings on related topics. • This information is added to the audio wikipedia for other people to listen to. This resulted in a wonderful and exciting learning experience and the opportunity to contribute to the knowledge society! The Digital Doorway ----------------- This is a very robust 4terminal computer system that is put into poor communities around South Africa to provide a means for people in that community to teach themselves basic computer skills. Funding is provided by the Department of Science and Technology Most of the software and content on Digital Doorways is open source. There are currently 24 Digital Doorway sites in South Africa running Mandrake Linux. This year we are installing a further 100 3-terminal Digital Doorways, running Xubuntu Linux. Content on the Digital Doorway includes: Open Office Drawing programs Educational Games Educational Videos Health Information Science Experiments Wikipedia Gutenberg Books And lots more. A Digital Doorway consists of 1 server, 2 fat clients, and 1 Mindset satellite receiver. Future DD's will be connected to a local MESH network Overview • • • • • • • • Access in South Africa The Challenge The FMFI Philosophy FMFI Projects – Overview FMFI Projects – Technical Technical Development Challenges and Next Steps Conclusions Challenges and Next Steps • • • • Community ownership – “bottom-up” approach Understanding the benefits of technology Sustainability models More research in understanding the human/technology interface • Scalability and replicability • INFLUENCE Conclusions • Innovation is key to Africa • Empowering regulatory policy • Health, education, community development • Understand how people interact – not technology “push” • The journey • Publication 2006 Thank You Chris Morris Ajay Makan Tel: +27 (0)12 841-2509 Fax: +27 (0)12 841-4720 Tel: +27 (0) 12 841-4009 Fax: +27 (0) 12 841-4720 E-mail: cmorris@csir.co.za E-mail: amakan@csir.co.za URL: http://www.csir.co.za URL: http://www.meraka.org.za URL: http://www.fmfi.org.za URL: http://wirelessafrica.meraka.org.za URL: http://csircoin.blogspot.com/
