Many developing countries simply do not
have the infrastructure to support either cable or DSL
broadband technologies. In fact, many such countries are
already widely using proprietary broadband wireless
technologies. Even in such regions however, it is very
unlikely that either Cable or DSL technologies would
disappear. The business case and basic infrastructure often
dictates that the cheapest solutions will predominate. In
many areas in developing nations, it may be cheaper to
deploy Cable and DSL in the cities at least for fixed
applications, whereas WiMAX will dominate outside of
major towns.
