The Affordable Long Range Wireless Connectivity project aims to extend the coverage of rural telecentre implemented in remote rural areas where there is zero telecommunication infrastructure available.
This research works's main objectives are as follows:
To reach out, maximize and extend network connectivity and coverage of the existing eBario telecentre into nearby villages of up to 10km away
To design affordable rural-proof wireless relay technology that is power self-sufficient, ease of transportation and deploy-able by the locals.
To create greater impact of a single VSAT Internet gateway investment by enabling larger Internet coverage penetration limited by geographical distance.
The following are some photo sharing related to this research works since year 2009.

Site Survey at Pa Ukat & Relay Station Installation at Prayer Mountain, Bario
15 August 2010 - 21 August 2010
We were identifying the potential villages by penetrating to the heart of jungle of Pa Ukat. Some insects attack during site survey at Pa Ukat.

Steep jungle trail up the Prayer Mountain.
A good and challenging experience for researchers.
Raining on the way up the mountain. We take shelter at the church located half way.
As ground surface getting slippery, the journey becoming more challenging.
Setting up and configuring equipment under the sun. we were taking shelter using a rain coat. Most of the time, Bario will have raining during afternoon. So, we will cover our hardware with few big black plastic bags and waiting for the rain to pass.

Extend network to Pa Umor
4 September 2011 - 8 September 2011
Thick bushes killed the wireless signal,
hence an alternative cabling has been laid across the 150m bushes to bridge the coverage gap.
Warning! Ants Inside!

This project has implemented 4 relay stations in Bario, relaying coverage and connection to 7 nearby villages, Padang Pasir, Ulong Palang, Bario Asal, Arul Dalan, Pa Ramapuh, Kampung Baru, and Pa Umor. The longest hop is 8km and the highest relay station deployed is on Prayer Mountain, 450m above Bario ground. The system has been serving the Bario community of 1000 people in the Kelabit Highland since 2010. Since then, this long range wireless network has been evolving and upgraded to meet the new needs of the rural communities as time pass by. With WiFi enabled mobile devices such as smartphones and tablets getting common, cheaper and more villagers own them, the role of telecentre now has been more into providing connectivity and bandwidth rather than computing facilities and services; the long range wireless system also in the process of evolving its CPE unit into new design of power-self sufficient WiFi hotspot system at remote villages. This project has also defined a standard model for easy and affordable telecommunication connectivity replication to other remote rural sites. This helps accelerating the effort in bridging the digital divide, which all these while been restricted by the high deployment cost of modern telecommunication infrastructure. The low adoption cost will increase the possibility of system self-sustainable by the local community when the project fund from the government finished. A service development platform has also been created through this project where other IT services can ride on this platform in order to deliver new, useful and relevant applications to the rural community more easily. The also open up more opportunity and accelerate the social economy development as more people can now be connected and resources are now easily reachable.
