WiMAX proposes challenges to providers of DSL, as well as, cable-modem service as its design can accommodate varying ways to transmit data. One: http://computer.howstuffworks.com/ip-telephony.htm" Voice Over Internet Protocol (VoIP) enables individuals to use a broadband Internet connection to "phone" long-distance and internationally. (Grabianowski and Brain) Some experts foresee a close race for fixed WiMax broadband services to win over other broadband technologies. Others who study this issue contend, however, as WiMAX can provide the bandwidth, identical to fiber alternatives, including, DSL, at a fair, marketable expense, it can convinces competitors' customers to switch to their fixed wireless version of services. Even though controversies exist as to whether WiMAX can compete with cable, DSL and 3G, criteria to be considered includes that a normal "hot zone," or "cell" may include an area of 1-6 miles. WiMAX, on the brighter side,.".. features a more bandwidth-efficient radio technology that can support data rates up to 100 Mbps in the same 20-MHz channel that 802.11a and g wireless LANs use to deliver 54 Mbps. Most importantly, the 802.16 access protocol is designed for carrier services and can scale to hundreds of simultaneous users." (Finneran) Finneran contends that DSL services, as well as cable, which have been providing services longer than WiMAX, are currently available to approximately 80% of individuals in the United States. Their technology reportedly focuses on the end user, while WiMAX's marketing focus will at first target equipment providers and carriers. In time, however, because WiMAX will not have to run cables, its costs could prove less expensive than fees currently charged for high and low speed Internet subscriptions. WiMAX could win against competitors as it could also potentially provide high-speed services in rural and suburban areas now serviced by the dial-up modem handshake with traditionally slow connections and time-dawdling downloads; areas considered too costly to wire by telephone and cable companies. Mathias, and Phifer believe: "There's little doubt that this WiMAX application will replace proprietary fixed wireless broadband over the next decade."
Conclusion
Just as dates projected for WiMAX to be able to provide full services differ and as reports regarding specifications of services are frequently diverse, experts also regularly disagree regarding WiMAX's future. Johnson, however,...
150). Already, the major telecommunication companies are adopting WiMAX into their business plans. "U.S. operator Clearwire plans to launch 2.5GHz WiMAX services this year. The company's Xohm service aims to start operations in Baltimore in September, followed by Chicago and Washington, D.C., before year-end" (Lemon 2007, p1.). Computer giant Intel is adding WiMAX as an option to its Centrino 2 laptop chip platform in 2008 and making them available in those
Also the alternative voice over IP providers such as Vonage, at & T. is expected to enhance the market share during the period. The demand for wireless connectivity by the direct consumers will also increase having wide choices to choose from like 3G, Wi-Fi, WiMAX. The SSLs and VPNs will dominate in the field of single-user remote access while the IPSec based installations will be resorted to in respect
To get a sense of how effective these metropolitan WiMAX networks are, it's useful to look at a WiMAX Scenario Analysis, which is shown in Figure 1. This schematic diagram shows how the various clients for a system would interact with base stations as subscribers, followed in transmission, aggregation and multi-service core aggregation of messaging. Figure 1 illustrates best practices in creating a WiMAX network across a broad metropolitan
City and municipal governments can also benefit greatly from the development of a Municipal Wi-Fi network in that fire, police, safety and medical equipment can be more effectively optimized in its used across broad geographic areas (Zhang, Schiffman, Gibbs, Kunjithapatham, Jeong, 2009). Using these forms of communication would also allow for greater responsiveness to emergency situations and a more effective series of strategies for managing ongoing communications across all
Mobile phones are another major area of emerging technologies. Not just for phoning home anymore, mobile phones are becoming more and more robust, integrating full PDA functionality and even permitting streaming video content. Communications providers offer the biggest obstacles in seamless digital streaming, because of the confusing array of services and relatively poor download speeds. Finally, consumers are becoming increasingly sensitive to the possibility of identity theft. As technology
82). Both desktop and Web widgets have the same basic components. Fundamentally, they use Web compatible formats, even if intended to run in a desktop environment. This means that the core of the widget is HTML and CSS code which contains the actual content of the widget, namely text, linked images/video or content pulled from a server of Web service. Alternatively, the widget content can be created using Flash, although
