2What are the forces of influence?
Work becomes an activity not a location
3WLAN Value Proposition
- WLANs help improve
- Mobility
- Personal Productivity
- Responsiveness
- Coverage
- Efficiency (cost savings)
- Flexibility
Mobility need and greater productivity were at
the top of a recent WLAN end user survey
conducted by Phillips Infotech
4Growth in Mobility
5End user WLAN access penetration in Europe
6Reasons for WLAN adoption
- The desire of individuals to be be mobile and be
able to work flexibly - The proliferation of WLAN peripherals-Laptops,
PDAs etc. - The gradual Resolution of security concerns
around WLAN - Sustained Price Erosion of WLAN hardware
- WLAN can provide a reasonable ROI based on
productivity improvements.

12Enterprise Campus Deployment
- 1000 Employees in 1 buildings, 45 APs
- Assume 30 of employees use WLAN for Mobility,
Increased time spent online and being
productive5 mins/day - Average hourly wage 10/hour
- Increased contribution due productivity
gains5,100/month - Paybacklt8 months
13Solution to Security Concerns
- WLAN security switches provide security overlay
through Encryption based VPNS-SSL and IPSec make
WLAN secure - WLAN security Switches enables enterprises to
detect unauthorised or rogue WLAN devices in the
network - WLAN security switches authorise users and are
able to define access capabilities for users
based on identity - 802.1i is being standardised and a phase 1 of
this standard is available in WLAN today
