Specifically, a wireless LAN client sending traffic to the wired LAN sends a packet to a lightweight access point, which encapsulates the packet using the Lightweight Access Point Protocol (LWAPP). With split-MAC operation, an access point is considered to be a “lightweight” access point, which cannot function without a wireless LAN controller (WLC). Mobility-Wireless mobility services include security threat detection, voice services, location services, and guest access.Īside from autonomous mode, Cisco unified wireless networks can alternatively operate in split-MAC mode.An example of a wireless network management solution is the Cisco Wireless Control System (WCS). Network management-Just as enterprise LANs benefit from network management solutions, a wireless LAN can also use network management solutions to enhance security, reliability, and to offer assistance in WLAN deployments.Network unification-To offer wireless clients access to an organization’s resources, the wireless network must be integrated (that is, unified) with the wired LAN.Access point-Wireless access points offer network access for wireless clients.Clients-A wireless client device is typically an end-user device (such as a PC) that accesses a wireless network.However, having an autonomous access point tasked with all these responsibilities can limit scalability and can hinder the addition of advanced wireless services.įive primary components comprise the Cisco unified wireless network architecture: Traditional WLANs use an access point in autonomous mode, where the access point is configured with a service set identifier (SSID), radio frequency (RF) channel, and RF power settings. The wireless access point allows a wireless client to reach the rest of the network.
Wireless clients (such as a PC or PDA) access a wireless access point, using half-duplex communication. Wireless local-area networks (WLAN) offer network access via radio waves. Introducing the Cisco Unified Wireless Network Specifically, after an introduction of the Cisco unified wireless network, this section examines network controller technologies and presents guidelines for wireless network design in enterprise networks. This section introduces the Cisco unified wireless network architecture. Wireless networks are experiencing widespread growth because of their availability, flexibility, and service offerings.
