In just a few short years, WiMax has become a disruptive force in the wireless industry.
As the first 4G wireless technology, WiMax has the potential to do for broadband what the cell phone did for voice and provide high-speed internet access for millions of users globally.
At this time there is little controversy over the fact LTE (Long Term Evolution) will become the dominant global 4G wireless technology over the next ten years. The only real issue at this point is when most carriers will opt to migrate to LTE and how long HSPA+ and CDMA EVDO Rev A will delay LTE deployments.
But the wireless world does not just include mobile wireless, particularly high-end, 3.5G and 4G, mobile wireless. India and China, the Middle East and Africa, the South American continent and parts of the Asia-Pacific region are examples of this; lower-tier technology markets due to spending constraints of the subscriber audience.
Many areas within these regions are also severely lacking in broadband infrastructure due to the same lack of spending power among the potential subscriber audience. This is changing however due to government efforts, falling prices on broadband access and cheaper access devices, such as the ultra-low-cost PC.
