802.16 standard was developed by the Institute of Electrical and Electronics Engineers (IEEE), called WirelessMANTM, provide new perspectives in high-speed Internet access without relying on network or cable modem. In 2002 formed a forum Worldwide Interoperability for Microwave Access (WiMAX), which refers to the 802.16 standard and is in charge interconnect various technical standards that are globally into one unit. WiMAX technology is cheaper than other broadband technologies such as digital subscriber line (DSL) or cable modem. The connection speed or new technological advances are not only an important aspect which should be evaluated, but both are facts which do not secure the wireless transmission to communicate.Security aspect is very important for broadband technology in accessing information from the Internet. This paper discusses about the development of WiMAX, the difference with WiFi, there are features and safety systems found on WirelessMANTM technology based on 802.16 standard specifications. IEEE 802.16 standard provides an easy Internet access to metropolitan areas with only establish several base stations (BS) which can either coverage millions of subscriber (SS).
WiMAX technology is a solution for urban or rural areas that have not been developed in the provision of internet access. Encryption of data used is data encryption standard (DES) and authentication on each client / subscriber station (SS) is very good with X.509 certificates are unique, reliable and dependable toughness.
