36 THE RIGHT TRACK TO WI FI When your organization is on the move, enterprise-class infrastructure is the ticket to secure and efficient network access. come to expect from wired networks. As increased usage puts stress on organizational wireless networks, staff members are discovering --- and voicing concerns about --- bandwidth bottlenecks, performance problems and coverage dead zones. Security concerns are also driving technology and systems security managers to take a long, hard look at both their wireless and wired infrastructures. In the current computing environment, users tend not to differentiate between wired and wireless access. Security policies and technologies, therefore, need to bolster protections at the point where users connect to the organization's systems and network infrastructure --- no matter how those connections are made. Deploying an Enterprise-class Infrastructure To build an enterprise-class Wi-Fi network, an organization should follow a five-step process: or most organizations, limited wireless local area networks (WLANs) started out as a convenience --- a simple way to let guests have an Internet connection while doing business onsite. Now, WLANs have become a critical resource for both staff and guest users. Staff members are using an increasing number of wireless devices. In addition to notebooks, they employ smartphones and tablets as tools to read e-mail, manage contacts and calendars, and carry documents with them. BYOD is no longer just a hot buzzword. Everyone from the top down wants the ability to be productive, whether they're in the office or on another continent --- and they want to be able to work using their own notebook computer, smartphone or tablet. In addition, staff and visitors working or attending meetings need secure and effective Internet access. ey must be able to connect to their own networks to retrieve and share information as well as to collaborate with the organization's users. Assessing the Situation Growth in the need and demand for wireless services has highlighted the often ad-hoc nature of how wireless networks have been deployed in buildings and on campuses. Network managers with meticulously designed and managed wired LANs are discovering that their wireless network's Quality of Service (QoS) doesn't match what users have THE PERCENTAGE OF INCREASED PRODUCTIVITY IN ORGANIZATIONS THAT HAVE IMPLEMENTED A WIRELESS LAN. 27% Source: Wireless Networking Basics IV: Planning and Deploying a Wireless LAN (squidoo.com)
