•  Cost avoidance—Cisco customers’ claim that as many as 50 to 80 percent of corporate cellular calls are made between employees located 

within the same campus. Wireless voice over IP allows the business to route these calls over the internal Wi-Fi network and  

avoid the cellular carrier rate charges.  

•  Universal telephony—Many companies have locations in which voice services are not currently available for all employees, such as retail 

stores, distribution centers, warehouses, and manufacturing floors. By deploying wireless voice over IP, the business can provide voice 

services, including a direct dial extension and individual voicemail to every employee. Mobile telephony improves productivity by increasing 

call completion and reducing the time spent accessing voicemail.  

•  Decreased support costs—Traditionally,  non-employees who visit the business 

either go without network access or rely on the IT department to securely configure 

their PCs to work on the network. By providing wireless guest access, the business 

can significantly reduce the cost of providing network access to guests and 

contractors and do it in a secure and manageable way. 

•  Partner services—Guest services are ideal as a single network platform for 

offering secure network access to multiple constituents. Locations such as factories, 

retail stores, and airports often require a single infrastructure for multiple 

companies. Using guest access, a business can provide its partners with wireless 

network access without the need for each partner to individually deploy their own. 

•  Physical security—The pervasiveness of the wireless network lends itself to 

physical security applications such as video surveillance and facility control (for 

example, badge reading). While these are not new applications, physical security 

can be delivered in a more cost-effective and pervasive manner than previously possible.

•  Rogue network containment—Businesses continue to struggle with the containment of rogue wireless networks because of the ease with 

which users can purchase and deploy consumer-grade Wi-Fi access points. Integrated RF monitoring capabilities allow the wireless system 

to detect the presence of rogue activity and contain it. By combining RF monitoring with location services, the network can provide precise 

location details on where the rogue activity is occurring so that it can be physically removed. 

Pervasive wireless deployments are providing business benefits far beyond productivity improvements. With wireless LAN mobility services, 

businesses can now deploy innovative applications to change business processes and provide new avenues for revenue growth and potential 

competitive advantage. As the adoption of wireless and mobile solutions expands, businesses will derive greater benefit from their 

infrastructure. 

Voice over IP has seen steady growth in the enterprise, with corporations taking advantage of the convergence of voice on their LAN or WAN 

infrastructure. With the same advantages of VoIP on wired networks in the enterprise, corporations are extending VoIP over Wi-Fi to reduce 

costs and improve communication efficiencies. 

For many businesses, making voice calls by telephone is crucial for communicating in a timely manner with customers and staff and between 

offices. By providing the underlying technologies for security, quality of service, and improved voice codecs, Cisco and Intel help IT 

departments leverage their mobile users’ unique working environments to aggressively compete in today’s marketplace. 

•  Cisco and Intel have combined their efforts to bring wireless technology from early adoption to maturation.  

Examples of this focus include: 

•  Founding members of the Wi-Fi Alliance to drive interoperability and increase market adoption of wireless networking. 
•  Relentless focus on standards development to deliver enhancements in wireless network features such as security,  

management, quality of service and throughput.
