Thin Client Computer Labs in Cambodia

Educational Support to Children in Underserved Populations (ESCUP)

goals of escup
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
thin clients bottom line
Thin Clients Bottom Line
  • Set of computer workstations working off a single server
  • Simulates a one to one computer experience
  • 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
students at kor secondary school in thin client computer lab established july 2008
Students at Kor Secondary school in thin client computer lab established July 2008
  • 11 workstations networked to 1 CPU
  • 2 Solar Panels provide sustainable power
  • If successful, 12 TC labs to be established in 2009
typical challenges to computer labs
Typical challenges to computer labs
  • High costs for equipment, set-up, maintenance, securtiy
  • High energy costs
  • Theft
  • Viruses
  • Upgrade needs and costs
kor secondary school pilot
Kor Secondary School Pilot
  • World Education is implementing partner
  • Local partner (Kampuchean Action for Primary Education) helped renovate classroom
    • tile floor and ceiling
    • dust proofing
  • Community provided $1,000 cost share
  • Microsoft advised on suppliers, software, etc

Unit cost for equipment in a thin client lab and a traditional lab

Thin Client Lab Traditional 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

energy costs
Energy Costs
  • Solar panels minimize recurring utility costs
    • $5,000 (2 panels) for Thin Client
    • $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)
    • CPU’s consume 150 watts and CRT monitors another 100 watts
  • UPS battery only required for teacher workstation
advantages
Advantages
  • Each station consumes 35 watts compared to 250 watts for traditional PC
  • Equipment is 44% cheaper and 88% reduction in energy use
  • Fewer moving parts per workstation = reduced maintenance needs and costs
  • Less vulnerable to USB/CD based viruses
  • Upgrade costs of RAM, software etc apply to only one computer, rather than several
  • Theft less likely (though monitors will be tempting)
disadvantages
Disadvantages
  • Dependence on a single server
  • Configuration and maintenance requires additional training
  • Higher energy consumption of server (?)
