• 90% of the world now has access to mobile networks
• Cost of wired broadband in developing countries decreased by 42% from 2008 to 2009, but is still 6-7 times higher than in developed countries
• Mobile penetration in the developing world will reach 68% by the end of 2010 (41% in Africa)

For every 10 percentage points increase in broadband penetration, there is an incremental increase in economic growth of 1.3 percentage points. This compares to the 0.8 percent increase for mobile phones. I would not have expected such a great differential – almost a 2x greater GDP boost via broadband than mobiles,

Yet, because of the greater reach and density of mobile phone usage – more mobiles than light bulbs in Uganda – they have a larger aggregate effect than broadband, for now. Soon though, we should see the new broadband connections in East Africa competing with mobile phones in penetration and usage.
