INTRODUCTIONINTRODUCTION
• A big challenge for rural community to access wireless broadband – – Internet– Voice call
• Why this occurs??– High Cost (Deployment, Maintenance)– Low scattered population resulted to low revenue– Low power supplu problem (solar limitation)– Environment (Hills, Rivers)

DISCUSSIONDISCUSSION
• New version of computers are provided • Insufficient internet networks • Internet connectivity is extremely slow– The data rate of 20 Mbps shared with other surrounded
schools– Unable to access internet during peak hours – Difficulties to key in students’ marks into the online
system– Ineffective ICT lessons to indigenous students
• Insufficient power supply with solar panel9
CONCLUSIONCONCLUSION
• Insufficient ICT facilities – low bandwidth• Slow internet connection for all schools -
ineffective• The technology used is VSAT and WIFI – slow
evolution compared to other countries• Power interruption affects the internet service
