he success of WiMAX could be hindered by a lack of common spectrum availability in different countries, according to a report by the U.K.-based Organization for Economic Co-operation and Development (OECD). “Many credit a nearly globally unified spectrum band at 2.4GHz for the success of WiFi. The harmonized spectrum band has allowed equipment manufacturers and consumers to benefit from economies of scale, effectively increasing supply and lowering prices for equipment,” said the report.
