The SchoolSat InitiativeSatellite Technology as an Access Technology for Schools Sally Reynolds, ATiT Belgium
Satellite Technology in Education • As a way to provide two way access to the Internet particularly in rural schools and learning communities unlikely to receive broadband otherwise: Unicast
Satellite Technology in Education • As a way to provide large scale content distribution of multimedia-rich educational material to schools and other learning communities: Multicast
Background to SchoolSat • ATiT study for ESA as part of TRAPEZE Project 1999-2000 on satellite technology as a possible solution to schools’ access problems identified opportunities • Demonstrated two-way Internet services via satellite to several national authorities and agencies • Formed consortium and applied for funding to ESA for trial in Ireland to: • Prove technical viability including installation and maintenance • Identify patterns of usage amongst school population • Provide show-case
Initial impetus for SchoolSatAccess issues in Ireland 2001 • 70% Primary schools < PSTN • 11% Primary schools ISDN • 6% Secondary schools < PSTN • 12% Secondary schools ISDN • 1% Broadband (cable or ADSL)
SchoolSat for Donegal 2-way satellite Internet access for 10 secondary schools: provision of hardware, connectivity, IT support, training for teachers and applications Partners: • ATiT • Web-Sat • NCTE • Donegal Education Centre Supported by European Space Agency with 50% funding under ARTES 3 programme
Two-Way Satellite Internet Connectivity Outdoor: 84 cm antenna Buncrana Carndonagh Indoor: Internet gateway PC connected to the school LAN
Project outcomes Evaluation by SchoolSat team and Independent Educational Advisor appointed by NCTE Technically: • Transfer per school varied, average less than 500 Mbyte per month. • Ratio 10:1 to 20:1 • No relation toSchool Size or Pupil/Online PC ratio • Minimum Faults, mostly lack of user familiarity • Issues to do with LANs, security, temporary nature
Project outcomes from an educational point of view • … facilitate greater use of the Internet in schools particularly allowing whole-class activities • … barriers to do with ideas, curriculum and access to the room • … Internet can be used in valid educational ways. • … teachers report the technology was highly motivating • … satellite access provides a viable connectivity particularly for rural schools
Current Status • Service remains operational, funding in 2003/2004 from Dept Education and Science and other bodies • 2004/2005 paid 50% by schools themselves and 50% as trial network for SchoolCast trials • National Broadband service roll-out currently underway, ITT issued in July 2004 – results expected November 2004, first schools to be connected in Spring 2005
Broadband Service to Irish Schools Key features to the proposed scheme: • Move from decentralised service with budget given to schools individually to pay for Internet services to centralised Schools Network to be managed by HEAnet (government owned academic network linking universities and other HE colleges) • Role of Satellite Technology in providing access moved from 1999 “too expensive and impractical to use” to “ the only viable solution in the short-to-medium term for more than 50% of Irish schools
Schools Tiered Model Ref. Datanet 2003
Options available: Leased Line, Satellite, Wireless (radio), DSL Ref. Datanet 2003
Rationale for choice • Leased line where the service can be provided at a comparable price to ADSL or Wireless, available at 78% of school locations BUT cost justifiable in only about 5% of locations • Where leased lines are not cost justifiable – wireless is next choice but general availability of mature offers are low • ADSL is 3rd choice but only available at about 37% of schools • While satellite is ranked lowest – strength lies in nationwide availability and represents easiest way to provide broadband to schools where other services not available (estimated at 60% of all schools)
Features of ITT • Mix of technologies: telcos can apply to connect all or just some schools • Delivery of connectivity to the school router • Contention rates required in responses to call • Open for best possible solution that can be offered • Discrepancy between money available to run the service for 3 years and the cost estimated, 3:1 • Responses must include upgrade path • Financed largely by contributions from telecommunications industry
Next steps… • Broadband roll-out to schools in Ireland due to begin in January and to be completed by September 05 using a mix of technologies including satellite • Schools content delivery trial to begin using a service product called SchoolCast in January, with service product commercially available summer 05 • Identifying other opportunities to utilise satellite technology for provision of access and/or delivery of content underway.
