I knew someone was going to raise the issue about the number of Telkodemonopolies lines being the reason for the low ADSL penetration rate, but it does not explain away the fact that the wireless broadband providers have in a much smaller timeframe managed to capture 50% of the broadband market which was almost exclusively controlled by Telkodemonopolies & its ADSL - why have 50% of broadband customers opted for a much more expensive wireless service instead of the [still] exorbitant ADSL service that Telkodemonopolies chooses not to provide in a timely manner and in relatively fewer areas compared to where HSDPA is available with combined coverage from Vodacom & MTN?Telkom has 5-7million landlines in SA. There are over 30million cell handsets currently in operation in SA, mostly Vodacom and MTN. So the potential customer base for the latter is much more than Telkom's. However, it is wrong to use these as base figures - one need to limit these ref points to those that also have computers / laptops. The potential BB market then suddenly drops quite dramatically (rough guess is about 2million). Only when computers / laptops is priced within an affordable range for the mass market in SA (<R2000) will the potential BB market increase resembling the 5-7 million Telkom or 30million+ cell customers.
PS: What GC posted about dual-connectivity [ADSL + wireless] is also a factor specifically amongst most forumites, but hard to extrapolate into the more general broadband customer base...
