WiMax: The Emergence of Wireless Broadband

This paper presents WiMAX technology (worldwide interoperability for microwave access) that aims to provide business and consumer wireless broadband services on the scale of the metropolitan area network (MAN). WiMAX can be used in disaster recovery scenes where the wired networks have broken down. In recent hurricane disasters, WiMAX networks were installed to help in recovery missions. Similarly, WiMAX can be used as backup links for broken wired links. The certification working group has developed a WiMAX product certification program, which aims to ensure interoperability between WiMAX equipment from vendors worldwide. The certification process also considers interoperability with the high performance radio metropolitan area network (HiperMAN), the European Telecommunications Standards Institute´s MAN standard
