Total Economic Impact Study of Unified Wireless Network
- 8 -
Analysis
As stated in the Executive Summary, Forrester took a multistep approach to evaluate the impact
that implementing Unified Wireless Network can have on an organization:
that implementing Unified Wireless Network can have on an organization:
• Interviewing Cisco Systems’ marketing and technical sales teams.
• Conducting in-depth interviews of four organizations currently using Unified Wireless
Network infrastructure.
• Constructing a common financial framework to illustrate the costs and benefits associated
with the migration.
• Constructing a composite organization based on characteristics of the interviewed
organizations.
Interview Highlights
A total of four interviews were conducted for this study, involving representatives from the following
companies:
companies:
1. Fortune 500 automobile manufacturer.
2. Global medical devices manufacturer.
3. A not-for-profit foundation for medical education and research with approximately 2,500
physicians and scientists.
4. A regional not-for-profit healthcare provider operating more than 20 hospitals.
The four in-depth interviews revealed:
• By centrally managing the wireless network infrastructure components, interviewees
reduced administrative costs associated with day-to-day wireless network management.
Releasing service set identifier (SSID) updates and/or configuration from a central location
allows network administrators to reduce travel time between offices and eliminate the
troubleshooting effort required to detect human errors caused by the annual roll out of
manual access point updates.

• Using the offered functionality, interviewees are proactively monitoring and detecting
wireless issues, and in most instances, resolving them before end-users experience a
failure. This reduces calls to the help desk.
failure. This reduces calls to the help desk.
• By using the “lobby ambassador” feature, organizations can specify a period that a guest
account remains active and other guest access account parameters centrally while allowing
administrative “front desk” staff to issue login credentials to guests. Interviewees indicated
that this allows them to reduce IT staff time to track guest access. Interviewees also
improved guest productivity for third-party visitors such as lawyers, auditors, consultants,
and contractors by allowing them to have high speed wireless guest access as a
replacement for expensive analog lines or carrier-based broadband connections to the
desk.
