Africa’s ICT Infrastructure
Notes 1. The analysis in this chapter was originally carried out in 2007 by Mayer and others (2009), using data from 2006. Some parts of the analysis were updated in 2009. 2. This analysis includes only GSM networks. Similar data on networks using the main alternative standard, CDMA, are not available. This does not substantially affect the conclusions of the analysis, because CDMA holds a small proportion of the total mobile voice market in Africa, with only 4 percent of the total voice subscriber market. Angola is one country where there is an extensive CDMA network, but few others have CDMA networks that cover areas of a country in which GSM networks are not present. 3. For countries for which data are available, which varies from year to year. 4. World Bank 2009; World Bank staff analysis. 5. Assuming ARPU of $10/month.
