Cisco and Intel—Five Myths of Wireless Networks 
Page 1 
Five Myths of Wireless Networks 
 
IT professionals who have resisted deploying pervasive wireless networks based on 
earlier assessments need to revisit their decisions in light of a new generation of 
standards, technologies, and products.  
“As organizations embrace wireless and 
mobility to increase productivity, 
enhance collaboration, and improve 
business flow, a unified wireless  
and wired network provides the high 
levels of security, scalability,  
and resiliency required of today's 
business-critical applications.”

The primary reasons IT professionals cite for not adopting pervasive wireless are: 
•  The benefits of a wireless network versus a wired network are not clear. 
•  There are security threats to wireless networks. 
•  The complexity of wireless networks—and the resources required to deploy and 
support them—are too costly.  
•  Wireless technology is still not mature. 
•  Aside from data mobility, the business value of wireless networks isn’t evident. 
This white paper addresses the top concerns of IT professionals who resist the 
deployment of pervasive, enterprise-wide wireless networks. It identifies these 
reservations based on the experience of Cisco Systems
®
 and Intel in leading new 
efforts in wireless standards and working with enterprise customers. By presenting 
advances in wireless technologies, products, and standards, this paper challenges 
the outdated perceptions that currently prevent many businesses from capturing the 
tangible benefits of pervasive wireless networks. 
Myth #1: Wireless networks provide limited benefits compared 
with wired networks 
Many IT professionals do not see the business case for wireless networks given the wired Ethernet infrastructure that is currently in place. 
While wired networks offer a more deterministic medium for data transfer, they cannot offer the pervasive connectivity inherent in wireless 
networks, which are designed for today’s mobile computing environment.  
A key driver for pervasive wireless connectivity is the increase in the number of mobile devices capable of connecting to the network. As client 
devices expand in form factor and functionality, the benefit of wireless connectivity grows. Analyst firms confirm that for the first time ever, the 
shipment of notebook computers has surpassed desktops. An estimated 95 percent of those notebook computers have embedded Wi-Fi. And 
the growth of mobile wireless notebook computers shows no sign of slowing. Notebook computers in the enterprise are expected to grow at a 
compounded annual growth rate (CAGR) of 18 percent between 2005 and 2010. This is a significant trend for IT departments because the
