1 A MERICAN I NSTITUTES FOR R ESEARCH Thin Client Computer Labs in Cambodia Educational Support to Children in Underserved Populations (ESCUP)

2 A MERICAN I NSTITUTES FOR R ESEARCH Goals of ESCUP Address the needs of improved educational access and quality to marginalized groups in Cambodia including ethnic minorities (Muslims groups-such as Cham-and highland peoples), children with special needs, the very poor, girls, and children infected or affected by HIV/AIDS Address the needs of improved educational access and quality to marginalized groups in Cambodia including ethnic minorities (Muslims groups-such as Cham-and highland peoples), children with special needs, the very poor, girls, and children infected or affected by HIV/AIDS

3 A MERICAN I NSTITUTES FOR R ESEARCH Thin Clients Bottom Line Set of computer workstations working off a single server Set of computer workstations working off a single server Simulates a one to one computer experience Simulates a one to one computer experience Potential benefits: cost savings from reduced equipment and energy needs, low maintenance requirements Potential benefits: cost savings from reduced equipment and energy needs, low maintenance requirements Potential hazards: centralized dependence on a single server, high energy needs for server Potential hazards: centralized dependence on a single server, high energy needs for server

4 A MERICAN I NSTITUTES FOR R ESEARCH Students at Kor Secondary school in thin client computer lab established July workstations networked to 1 CPU 2 Solar Panels provide sustainable power If successful, 12 TC labs to be established in 2009

5 A MERICAN I NSTITUTES FOR R ESEARCH Typical challenges to computer labs High costs for equipment, set-up, maintenance, securtiy High costs for equipment, set-up, maintenance, securtiy High energy costs High energy costs Theft Theft Viruses Viruses Upgrade needs and costs Upgrade needs and costs

6 A MERICAN I NSTITUTES FOR R ESEARCH Kor Secondary School Pilot World Education is implementing partner World Education is implementing partner Local partner (Kampuchean Action for Primary Education) helped renovate classroom Local partner (Kampuchean Action for Primary Education) helped renovate classroom tile floor and ceilingtile floor and ceiling dust proofingdust proofing Community provided $1,000 cost share Community provided $1,000 cost share Microsoft advised on suppliers, software, etc Microsoft advised on suppliers, software, etc

7 A MERICAN I NSTITUTES FOR R ESEARCH Unit cost for equipment in a thin client lab and a traditional lab Thin Client LabTraditional Lab Student Workstation Equipment Thin Client unit or CPU $145$480 Monitor and Keyboard$180$120 Surge Protector/Battery$5$90 Student Workstation Total$330$690 Teacher Workstation Equipment Thin Client unit or CPU $720$480 Monitor and Keyboard$180$120 Surge Protector/Battery$90$90 Printer$200$200 Teacher Workstation Total$1,190$890 Lab set-up with 11 student workstations and one teacher workstation $4,820$8480

8 A MERICAN I NSTITUTES FOR R ESEARCH Energy Costs Solar panels minimize recurring utility costs Solar panels minimize recurring utility costs $5,000 (2 panels) for Thin Client$5,000 (2 panels) for Thin Client $30,000 in solar panels needed for traditional lab$30,000 in solar panels needed for traditional lab LCD monitors higher up front cost but use 65% less energy (30 watts + 5 for thin client unit) LCD monitors higher up front cost but use 65% less energy (30 watts + 5 for thin client unit) CPU’s consume 150 watts and CRT monitors another 100 wattsCPU’s consume 150 watts and CRT monitors another 100 watts UPS battery only required for teacher workstation UPS battery only required for teacher workstation

9 A MERICAN I NSTITUTES FOR R ESEARCH Advantages Each station consumes 35 watts compared to 250 watts for traditional PC Each station consumes 35 watts compared to 250 watts for traditional PC Equipment is 44% cheaper and 88% reduction in energy use Equipment is 44% cheaper and 88% reduction in energy use Fewer moving parts per workstation = reduced maintenance needs and costs Fewer moving parts per workstation = reduced maintenance needs and costs Less vulnerable to USB/CD based viruses Less vulnerable to USB/CD based viruses Upgrade costs of RAM, software etc apply to only one computer, rather than several Upgrade costs of RAM, software etc apply to only one computer, rather than several Theft less likely (though monitors will be tempting) Theft less likely (though monitors will be tempting)

10 A MERICAN I NSTITUTES FOR R ESEARCH Disadvantages Dependence on a single server Dependence on a single server Configuration and maintenance requires additional training Configuration and maintenance requires additional training Higher energy consumption of server (?) Higher energy consumption of server (?)
