Wireless technology offers immense potential for competitive advantage, starting right now -- but today's wireless landscape can be extraordinarily confusing. This book gives decision makers the clarity, insight, and practical methodology they need to identify the right wireless solutions -- and implement them. Ian S. Hayes offers a practical framework for understanding today's complex array of wireless devices, solution providers, technologies, standards, architectures, and acronyms. Through real-world case studies, practical examples, and illustrations, he helps you determine which wireless solutions offer the greatest business value in your environment -- and walks you through assembling and integrating those solutions. The book contains a detailed glossary of terminology, as well as a comprehensive list of software vendors and consultants, updated on an ongoing basis at the book's companion Web site.show more
