enterprises, this means improved asset utilization, and improved protection against theft and
inadvertent release of sensitive customer data, as well as reduced inventory management costs.
Voice Services
Voice over IP is rapidly gaining ground as the preferred method to deliver voice communications
within enterprises. By delivering voice and data over a single converged IP network, acquisition
and operational costs are significantly decreased. When voice over IP is deployed over wireless
LANs, these same benefits are multiplied by making mobile workers reachable anywhere and
anytime. Unlike cellular phone service, which is not economically feasible for large retail
organizations operating on extremely thin net margins, voice over wireless LAN (VoWLAN)
provides inexpensive, continuous, high-quality service when a pervasive wireless LAN is deployed.
Retail organizations can realize many benefits from deploying VoWLAN, including:
●
Improved customer service by freeing personnel from having to provide personalized
service only from fixed locations
●
Increased profits through operational efficiency and improved customer satisfaction
●
Improved communication by giving phone services and voicemail to each store employee
●
Improved responsiveness by making business applications, like inventory management,
mobile with wireless phones
The Cisco Unified Wireless Networks delivers voice services through unique enhancements
that support demanding real-time communications capabilities, including the following:
●
Industry-leading quality of service (QoS) and Call Admission Control (CAC) on the
wireless voice network, enabling voice and data applications to peacefully coexist
●
Power saving for extended handset talk-time battery life
●
Real-time RF scanning and monitoring of the RF environment, delivering a self-configuring,
self-optimizing, and self-healing wireless network to ensure the quality and availability of
voice services
●
Fast secure roaming across the campus while maintaining Wi-Fi Protected Access 2
(WPA2) security
●
Access points with MAC layer enhancements to intelligently handle voice and reduce voice
packet delays caused by retries
The Cisco Unified Wireless Network supports the widest variety of voice clients in the industry.
The Cisco Unified Wireless IP Phone 7920 is an easy-to-use IEEE 802.11b wireless IP phone
that provides comprehensive voice communications in conjunction with Cisco Unified CallManager
and Cisco Unified Wireless Network. In addition, the Cisco Compatible Extensions program gives
voice client manufacturers the ability to design current and future voice wireless innovations into a
wide variety of devices.
The Cisco Unified Communications system provides a full-featured, scalable, distributable,
and highly available IP telephony call-processing solution. The Cisco Unified Communications
system and its application partners, combined with Cisco’s voice-capable wireless infrastructure,
together enable retail employees to move around freely within their environments to support
customers and to maximize asset utilization. Employees have individualized voice extensions
with only an incremental cost increase over current retail enterprise voice costs.
