Wireless LAN technology is expanding rapidly in the commercial sector with the
introduction of products that will allow enterprise customers to build a secure,
reliable wireless infrastructure. This program provides a comprehensive overview
of the products, technologies, and design techniques that are used in enterprise
wireless LANs. The full range of wireless LAN applications will be covered along
with practical descriptions of capacities, access protocols, radio issues, design,
and management tools. This program is geared for network designers who need a solid
foundation in radio and a detailed understanding of the products and technologies
that will are used to build and maintain WLAN voice and data networks.
Who Should Attend
Communications analysts/managers, equipment vendors, and carrier representatives
who need a detailed, business-oriented understanding of wireless LAN and fixed-mobile
convergence applications, services, and technologies.
