Voice over WLAN Solutions Using Cisco Unified Wireless
Network Software Releases 4.1 and 4.2
Network Software Releases 4.1 and 4.2
Background
Infonetics’ long-term forecast for Wi-Fi
phone units is US$32.9 million by
CY2009, a 5-year CAGR of 203 percent.
And Wi-Fi phone revenue is projected to
reach $3.7 billion by CY2009, a 5-year
CAGR of 134 percent. This indicates
healthy growth for voice over wireless
LAN (VoWLAN).
The fundamental driver for the growth of
Wi-Fi phones is the simultaneous
proliferation of
●
Pervasive business WLANs
●
Public access to WLAN infrastructures (also called hotspots)
●
Voice over IP (VoIP) systems
●
Maturity of Wi-Fi phones and availability of 802.11a/b/g dual-band phones
This growth enables companies to take advantage of always-on connectivity for mobile devices,
improving productivity and reducing operational expenditures (OpEx).
Solution Overview
When considering voice over Wi-Fi, customers should seek a solution that supports:
●
An enhanced end-user experience: This directly increases the use of Wi-Fi phones,
allowing companies to reduce cell phone bills and positively impact employee
responsiveness.
●
Integration with the existing VoIP infrastructure: This facilitates rapid adoption of Wi-Fi
phones, as users only need minimum training and can take advantage of the same features
wirelessly as is available on fixed phones.
●
Simplified management: This facilitates the deployment of new devices, eases
troubleshooting, and provides network assessment tools to evaluate readiness of the
network deployment for VoWLAN.
