South Africa and the 2.6GHz Band Plan – Isolation or Harmonization

Martyn Roetter, July 24, 2009

Too late for WiMax?

Next generation mobile technology could relegate WiMax  to a niche position in Africa as a wireless broadband solution in a continent that has a higher penetration of mobile phones with internet access than fixed lines.

WiMax will face stiff competition from mobile networks, although it will still have a greater impact in those developing countries in which it is given a reasonable head start over mobile broadband networks in Africa – by mid-2008 there were already 14 commercial HSPA networks in nine African countries.
