WiMAX (Worldwide Interoperability for Microwave Access) represents a globally standardized broadband wireless access network designed to be used primarily as a solution alternative to DSL (Digital Subscriber Line) and cable access technologies. WiMAX systems are used for fixed, nomadic, portable (in the near future mobile) communication in access networks. Employing advanced and robust OFDM (Orthogonal Frequency Division Multiplexing) radio transmission technology WiMAX systems enable communication in NLOS (Non Line of Sight) conditions which makes them ideal for use in urban environments.
Cell based installation with cell radius from 3 to 10 km, based on IEEE 802.16d standard, will enable business and consumer users use of capacities over 40 Mbps per sector for various types of services such as Voice over IP communication, video transmission and Internet access (Triple Play services) with full Quality of Service – QoS. By employing adaptive modulation radio transmission techniques these systems enable wireless links over 50 km long (in line of sight environment) which is suitable for use in rural areas in need of broadband communication.
Mobile WiMAX networks, based on IEEE 802.16e standard, which are expected to become commercially available in the near future, will enable the use of broadband transmission capacities up to 15 Mbps with cell radius up to 3 km. It is also expected for WiMAX broadband wireless technology to be implemented into portable and PDA computers thus bringing fully mobile broadband services in residential zones and densely populated urban areas.
In the beginning of 2006 in the wider area of the city of Čakovec MICRO-LINK has completed the first commercial implementation of a certified WiMAX network for the needs of HT – Hrvatske Telekomunikacije. MICRO-LINK is able to offer a turnkey solution in WiMAX systems in terms of technical solution and implementation as well as provisioning of necessary equipment.
