What is WiMax?
WiMax which expands to worldwide interoperability for Microwave access is a budding telecommunication technology that uses different transmission modes to enable connectivity. This technology is based on the IEEE 802.16 standard. The existing transmission modes ranging from point-to-point links to wireless media are used for transfer of data for WiMax. The main idea behind this technology is to provide interoperability between the transmission modes without adding additional burden to the consumers.
WiMax can be used to connect Wi-Fi hotspots to internet. All the devices within the hotspot can then access internet without paying extra cost. Wireless devices can seamlessly connect to cable internet using wireless hotpot with the WiMax technology. Those places that have terrain unsuitable for establishing cable connection can use WiMax to establish connectivity with the rest of the world. This technology is useful for businesses that use different providers for providing wired and wireless communication services. Portable connectivity is ensured with the use of WiMax technology.
Last mile broadband access poses a limitation to the establishment of Wi-Fi hotspots. With the use of WiMax, this last mile connectivity problem can be eliminated. The technology in its emerging stage helped to regenerate communication links in Aceh, Indonesia during Tsunami in December 2004. The ferocious waves destroyed everything except an amateur radio. Thus, Aceh was completely cut down from the rest of the world. Under this tight situation, WiMax was used to bring broadband access to reconnect Aceh. It was during this time that the efficiency of WiMax was realized and widely accepted.
Client units for WiMax can be indoor or outdoor units. Using indoor units, it is possible to get internet access with a communication device. These indoor units can be deployed in home and offices. These are similar to modems that are normally used to connect to internet. Outdoor units are bigger and they are of the size of laptops. Installation requires some process similar to fixing a satellite dish. Once established, a variety of telecommunication devices can interact with each other easily.
The Wi-Fi service is presently limited by the range in which the service is provided. Connectivity cannot be obtained when the device is more than 100m from the hot spot. WiMax makes connectivity possible even when the devices are located 30 miles in the case of fixed stations. If WiMax service is provided by mobile stations, devices located in the range of 10 miles can access internet. The principle of allocation of services in WiMax is stable. Scalability is ensured as the subscriber station holds the connection once it is granted. The problems related to scheduling and workloads in Wi-Fi are efficiently handled in WiMax.
Latest advancement in WiMax is to use a single node as a base station and subscriber station at the same time. Every one including consumers, service providers, and operators can benefit from WiMax technology. In April 2001, WiMax forum was established and people are working on making improvements to WiMax technology. These people are responsible for broadband certifying wireless access products. Also, this forum helps the systems from different vendors to work efficiently.
