The second edition of WiMax Operator's Manual includes most of the material from the first edition, plus new discussions of • The ultra-high-speed mobile telephone standard, HSDPA • Ultrawideband (UWB) • Changes to DSL technologies • Mobile voice • Mobile entertainment • New backup systems The new edition also reflects the changes that have occurred in the industry over the last year and half, including the emergence of prestandards wireless broadband equipment with fully developed mobile capabilities, significant alterations in the competitive landscape, and the opening of valuable new spectrum for broadband wireless operators. Public broadband wireless data networks represent a truly disruptive technology, one that promises to break the monopolistic and oligopolistic status quo that still represents the norm in high-speed access today. Products that would enable such networks have existed for a number of years and in fact have been deployed in thousands of commercial systems throughout the world, but the lack of standards, the limited production volumes, and the consequent high prices have prevented the full potential of wireless broadband from being realized. Now, with the coming of a widely accepted industry standard, IEEE 802.16, and the introduction of microchips based on that standard by leading semiconductor companies, wi- less broadband public networks are becoming mainstream. | WiMax Operator's Manual by Daniel Sweeney, Hardcover | Indigo Chapters
