A short summary of this paper. Download Download PDF. Translate PDF. Many residents thus must do without broadband service. Wireless approaches could address this problem. Therefore, proponents Broadband with are advocating WiMax worldwide interoperability for microwave access , a technology based on an evolving standard for point-to-multipoint wire- WiMax less networking.
Craig Mathias, principal analyst for Steven J. As WiMax has gained traction, major companies such as British about the consortium. Telecommunications, France Telecom, and Qwest Communications have joined the forum.
The forum plans to begin certifying nology. WiMax, on the other hand, products by the end of this year, according to board member Dean Chang, who offers a standardized technology. It would also let equipment IEEE In addition, carriers without a mobile network could start Switching a WiMax system at relatively low cost. Residential Public Rerisi anticipates that WiMax will subscriber telephone Internet network provide high-speed network connec- service tions and thereby serve as a backbone provider for IEEE WiMax could thus offer a less expensive, easier to build infrastructure than the wire- Figure 1.
Initial plans are to use WiMax—a point-to-multipoint, broadband wireless- line WiFi backbones that DSL, cable, networking technology—for Internet access. Carriers would set up rooftop transceivers as or T1 systems currently provide. Each base station would use WiMax technology These factors, along with public to communicate with fixed, externally mounted subscriber antennas.
OFDM increases band markets to grow, predicted Rerisi. At these nous transfer mode. This lets vendors which address transmissions over a higher frequencies, IEEE This reduces WiMax has a long transmission quency ranges.
This flexibility lets ond on both the uplink and downlink. Thus, he noted, each station providers use different frequencies Providers could use multiple IEEE will probably serve an area within a depending on the range and speed For example, Wave- sat, in partnership with Atmel, hopes to produce them this year.
Fujitsu is 0 also working on WiMax chipsets. Intel plans to sell chipsets that will include Source: www. The products include both net- Figure 2.
As WiMax technology becomes more popular, equipment sales are expected to working circuitry and a radio. The grow significantly. So, it can provide a rich choice of service possibilities to voice and data network service providers.
In addition, WiMAX provides an ideal wireless backhaul technology to connect The most typical WiMAX-based architecture includes a base station mounted on a building and is responsible for communicating on a point to multi-point basis with subscriber stations located in business offices and homes. The customer premise equipment CPE will connect the base station to a customer as well; the signal of voice and data is then routed through standard Ethernet cable either directly to a single computer, or to an WiMAX-based solutions include many other advantages, such as robust security features, good QoS Quality of Service , and mesh and smart antenna technology that will allow better utilization of the spectrum resources.
WiMAX also allows the services provider to deliver many types of wireless access services. The WiMAX can be used on a variety of wireless broadband connections and solutions:. In , Intel Corp. In order to bring interoperability into MAN, the WiMAX Forum is focusing its efforts on establishing a baseline protocol that allows equipment and devices from multiple vendors to interoperate and that also provides a choice to buy equipment and devices from different suppliers.
Currently, there are no WiMax-certified products yet available in the market, but the race is already on. Intel is planning to offer WiMax transmitters by , and expects to ship WiMax devices for the home and office to take off by Also, Intel hopes that notebooks will begin to incorporate WiMAX technology during , and by , handsets for mobility will be available.
Fujitsu Microelectronics America Inc. Siemens Information and Communication Mobile also plans to build complete WiMAX-based solutions for establishing fixed, broadband speed metropolitan area wireless radio networks.

The WiMAX-based wireless solution makes it possible for the service provider to scale-up or scale-down service levels in short times with the client request.
Backhaul networks for cellular base stations, bypassing the Public Switched Telephone Network PSTN ; the cellular service providers can look to wireless backhaul as a more cost-effective alternative. The robust WiMAX technology makes it a nice choice for backhaul for enterprises such as hotspots as well as point-to-point backhaul solutions.
Backhaul enterprise connections to the Internet for WiFi hotspots.
