This paper Worldwide Interoperability for Microwave Access (Wimax) presents the features of the Worldwide for Microwave Interoperability Access (WiMAX) technology and discussion on comparing Wireless Fidelity (Wi-Fi) with WiMAX. Broadband technology is a need for the population. Internet Service Providers (ISPs) have challenges in order to have broadband solutions. Digital Subscriber Line (DSL) technology appeared to be pioneer solution.
Despite Wi-Fi in LAN solutions, it is used in MAN solutions also with bandwidth, coverage, and power consumption for the promotion of conformance and interoperability of the IEEE 802.16 standard, known as Wireless MAN.
The WiMAX is described as a standards-based technology that enables wireless broadband access to cable and DSL. WiMAX is not a technology, but rather a certification mark or stamp of approval.
Based on IEEE 802.16 and ETSI HiperMAN, WiMAX has common mode of operation, Concentrated in 2- to 11-GHz WMAN and Defines both the MAC and PHY layers. The IEEE 802.16 technical has evolved into three generations. They are IEEE 802.16, IEEE 802.16-2004, and IEEE 802.16-2005.
A WiMAX system consists of two parts. One is WiMAX tower and other one is WiMAX receiver. IEEE 802.16 supports two modes of operation, PMP and PTP. Point-to-point (PTP) link refers to a dedicated link that connects only two nodes, BS and subscriber terminal.
Topologies are Point-to-multipoint (PMP) and Mesh Topology. Mesh networks are wireless data networks that give the SSs more intelligence than traditional wireless transmitters and receivers.
WiMAX becomes the dominant standard for Wireless MAN networks in today’s world market. The importance of OFDM makes the difference between the 802.16 and 802.16a standard. There are prototypes and development kits using WiMAX standard that are used for education. There are also few products which have been introduced into the market that already contains the WiMAX standard. Market is the key word to take into account. Products need to be delivered as per the market needs.
