WiMAX technology is the basis of the IEEE 802.16 standard that allows data transmission services for Broadband Wireless Access (BWA) as an alternative to cable access or DSL. This teknologi is an attempt to answer the need for greater data rate, wide coverage, and compatibility between components in the network. Large throughput of course be an initial target of developing an access technology. This is driven by the increasingly diverse communications applications made by customers. With high data rate allows the network to be able to handle various kinds of transmission, both the transmission of voice, data, and video. WiMAX Forum states that only one Base Station, in theory, reach the cell coverage radius of 50 km with the ability of the system can transmit data at speeds up to 75 Mbps per carrier for the type of fixed and portable access
