WiMax security has been discussed in this paper. The lessons learned with WiFi’s deployment have given WiMax an advantage in providing a safer wireless network. The precautions taken with WiMax were not done for WiFi. These security measures were not taken at WiFi’s launch because the threats were unknown. Now that the threats are known and understood, they have been addressed prior to WiMax’s deployment. However, this does not mean that WiMax is flawless. There may be new threats that are unknown and will not be addressed until WiMax is launched. WiMax does have much potential. WiMax would allow customers a completely wire free network connection in their homes or businesses. WiMax would also provide better services for mobile devices. There are also some speculations for WiMax to be used in gaming consoles. While security is an important subject and was a main cause of delay in the first stages of development for WiMax, it has now been faced with technological down falls. Sprint Nextel is one of the main companies looking to bring WiMax to the US. The main cause for delay has been the Sprint Nextel backhaul links from the backbone to the towers. It has been unable to support the promised 4Mbps. Until recently there has been little hope that a resolution to this problem would surface. In July 2008, Sprint Nextel announced that a solution has been found. They will be teaming up with DragonWave, a Canadian company, to provide the backhaul links. This will allow all data passing from the backbone to the end user to travel over the air, and the towers will need only power links. With this new development a testing launch of WiMax to Portland, Oregon is ready now, and preparations for a launch in 2009 to LasVegas, Atlanta, and Grand Rapids. If these tests go well we could see a full commercial launch by 2010. However, Clearwire has successfully deployed WiMax to several cities in the US and has been the main WiMax service provider for the last few years. With the formation of the Open Patent Alliance (OPA), which includes Clearwire, Sprint, Alcatel-Lucent, Cisco, Intel Corporation, and Samsung Electronics, WiMax could be global in the next five years.
