An interesting article. It shows what can be done when all the options are on the table. Some of the comments in the article also apply to rich countries too, not just poor ones. Like the US's phone networks are very patchy. There are many places in the US were your mobile/cell phone gets no signal. This is a normal thing for them.
Also in the US mainly Google is building a fibre optic network in big cities and have now started expanding in to the small towns (I'm using City, Town and Village to seperate the population size).
This report shows that Internet connectivity can be made even in the less population dense areas. I do hope BT consider these smaller technologies in the future. I mean, we're only a small island, we should be at near 100% coverage.
Interestingly Obama made a speech about ISP's holding technology back. Since then a number of the big ISP's have all started building there own fibre networks.
