Role of Wireless Technologies in ICT4D

When we try to apply Information and Communication Technology (ICT) in the complex development process, one main challenge we face is the development of the necessary ICT infrastructure, especially in remote areas. Most of the ICT for Development (ICT4D) initiatives face the issue of sustainability due to the high cost of "last-mile connections".

As an example the Nenasala (Telecentre) initiative implemented under the e-Sri Lanka, ICT4D master plan in the country is facing many challenges of sustainability due to the connectivity cost as high as 30,000 LKR per month (for expensive wireless satellite connection). Newly introduced wireless last mile technologies such as Wi-MAX and HSPA can provide the same connectivity for a cost as low as 4,000 LKR. Dialog Broadband extended it services by providing low cost Wi-MAX wireless connections to some selected Nenasalas in different parts of the country.

When compared with wired connections, wireless is cheaper to implement and maintain specially in remote areas. So developing countries like Sri Lanka can get benefits of new wireless technologies and that would trickle down to all the citizens of the country. The fact that setting up wireless systems is so cheap has meant that its use has grown exponentially. As a result of this many have pinned their hopes on the wireless delivery of voice and data across Asia and other remote locations worldwide.

Wireless technologies play an important role in extending access to voice and data communications services to marginalized groups in society, especially remote areas in the country. The present rates of growth and levels of connectivity could not have been achieved without wireless in the access networks, for mobile as well as for fixed, and in the backbone networks. As per the World Information Technology Report, Sri Lanka has been positioned at the 66th place in the Network Readiness Index.

It is our hope that wireless technologies will continue to support uplifting Sri Lanka’s network infrastructure and allow people in the country to really reap the benefit of ICT and make national initiatives like e-Sri Lanka a successes.

OLPC Sri Lanka

One Laptop Per Child in Sri Lanka

OLPC has become a hot topic, olpc initiatives are under way around the globe. It is always good to see what this OLPC is and what are the benifits Sri Lanka can gain, basically how it can be used for sutainable development.

Following are some thoughts about the OLPC, positive and negative, without going for radical "YES" or "NO".

Some positive aspects;

  • Can reach five children with OLPC when we reach one child with normal PC.
  • Inbuilt Wi-Fi mesh network capability is ideal for an eVillage.
  • Minimal power consumption (<2w)>
  • Rugged encasement and rubber sealed keyboard make OLPC resistant to water, dirt and hardy use by kids.
  • Can be used for peer learning within a homogeneous children’s group in a village or a children’s home, etc.
  • Good teaching and learning assistant

Some negative aspects;

  • Specifically designed for kids, so have to target only that age group (normal PC for everyone)
  • Cost of ownership is higher, initiatives like Nanasala tries to reduce the cost of ownership by promoting common/shared access.
  • Does not promote the sharing of resources
  • Does Sri Lankan every child need a his/her own laptop, can our economy bare it?
