700+ Wireless Networking Abbreviations

Of all the communications services available today, wireless services are having the most dramatic impact on our personal and professional lives, enhancing personal productivity, mobility, and security.

The wireless industry worldwide is experiencing rapid innovation, increased competition, and diversity in service offerings—all of which have resulted in lower prices for consumers and businesses.

Wireless technologies and services have become so popular worldwide and sufficiently sophisticated and complex as to merit dozens of articles on the topic that are published every year. This encyclopedia is a quick reference that clearly shows the essential concepts of wireless, including services, applications, protocols, network methods, development tools, administration and management, standards, and regulation.
