Wireless LAN

With the introduction of wireless communication, wireless IP phones can provide voice communication within
the corporate WLAN. The Cisco Unified Wireless IP Phone depends upon and interacts with wireless access
points (APs) and key Cisco IP telephony components, including Cisco Unified Communications Manager
Administration, to provide wireless voice communication.
In a traditional LAN, IP phones and computers use cables to transmit messages and data packets. Cisco Unified
WLAN delivers security, scalability, reliability, ease of deployment, and management similar to wired LANs.
It includes RF capabilities that enable real-time access to core business applications and provides proven
enterprise-class secure connectivity. The WLAN is an integrated end-to-end solution that uses wireless IP
phones and APs, network infrastructure, network management, and mobility services.
