Hi,
Just read about moderately priced technology for long distant radio lines: http://ir.ubnt.com/releasedetail.cfm?releaseid=917339
These guys have resellers in many countries, incl. Africa and Asia. Cost of equipment is USD 400 (perhaps plus antennas, cables, etc.).
Is there any more cost/effecitve way to provide two way Internet to remote areas?
best,
adamk
