9. Wired and wireless convergence: campus infrastructureSecure and easy to manage Authentication QoS Per Service • Service • Telephone (Fixed/Mobile) • Welcome Center • Patients Records • ERP • Intranet • Extranet • Internet • Medical Images • Medical Video • Medical Monitoring • Broadcast TV • Public Video • Games • CCTV/Security • Profiles • Management • Resident Doctor • Nurse • Admin • Support Staff • Teacher • Student • Patient • Visitor • External Doctor • Supplier Access Rights Manageable Point-and-click

10. Because Voice is not just “another packet” on the WLAN • Quality of Service • In building roaming requirements and management • Laptops and wireless phones • Graceful handoffs • Security

11. Benefits of WLANs that carry Voice&Data Customer Care User Eficiency ROI Increased Business value Increase accessibility -> productivity =>customer care =>cost savings & control

12. Case Study and Applications

13. Case Study: University of North Carolina Hospitals • Four hospital, 684 bed facility with 19 remote community clinics • 5,900 full-time employees • 6,800 wired phones behind 5,300 Centrex phone lines • 44 separate nursing units • Approximately 40,000 patients annually

14. Goals of Wireless Phones for UNC Hospitals • Help make Nurses and Nurse Assistants more efficient • React faster to patient needs • Reduce overhead paging • Free up Hospital Unit Coordinator (HUC) • Integrate wireless phones with existing Nurse Call system • Must be compatible with integration software • Nurses sign-in for phone and patient rooms • Allow non-anchored departments to communicate remotely • EKG Team • Telecommunications • Facilities

15. Decision Factors and Details • Wireless technology and infrastructure • Cellular signal does not penetrate most of hospital building • Cellular use discouraged around hospital equipment • Cisco WLAN installed on all nursing floors for Computerized Physician Order Entry (CPOE) • Handset requirements • Phones must be very rugged • 24-hour usage and very physically tough environment • Evaluation process • Looked at proprietary systems and VoIP offerings – tested four vendors • Conducted four week test with one of the hospital’s most demanding nursing unit • Decided on winning system along with nurses

16. Healthcare Return on Investment Source: Journal of Nursing Administration, June 1995

17. The Industrial Environment • Business challenges • Maximize uptime and minimize downtime • Difficult to reach technicians and supervisors in large facilities • High-noise levels impair overhead paging systems • End-user devices need to be rugged and durable • Applications • Manufacturing • Distribution centers • Benefits • Key personnel are available in real-time • Eliminate paging delays • Leverage wireless infrastructure

18. Manufacturing Return on Investment • Pre-installation on-site user survey found that: • 50% of overhead pages went unanswered because personnel could not hear the page • Technicians lost 39 minutes on average due to unanswered calls and time spent traveling to a phone to answer a page • 30 out of 50 customer service calls were abandoned as a result of long hold times • Estimated $5,000 savings per month calculating all personnel time saved • Based on average salaries in a manufacturing plant and 40 hour work week • 10 shop managers • 8 maintenance technicians • 1 customer service representative

19. The Retail Environment • Retail challenges • Raise customer service levels • Increase store productivity • Competitive advantage • Applications • Store managers and directors • Department supervisors • Loss prevention • Buyers • Benefits • More responsive to customers • Callers spend less time on hold • Managers are always accessible • Eliminate overhead paging for a better shopping environment

20. The Hospitality Environment • Business challenges • Customer service is critical to the bottom line • Develop and retain customer base for ongoing revenue • Applications • Guest services • Meeting planners • Support staff – security, housekeeping, facilities • Benefits • Faster response to customers • Faster issue resolutions for higher customer satisfaction • Differentiation and competitive advantage • Leverage Wi-Fi infrastructure

21. The Corporate Campus Environment • Business Challenges • Large environment with diverse needs • Integrating legacy and emerging technologies • Increase productivity • Decrease costly overhead • Applications • Large enterprises • Colleges and universities • Benefits • Eliminate communication barriers • Reduce voicemail and phone tag • Support hoteling and hot-desking environments • Leverage existing communication technologies

22. Application Summary • Wireless telephony has benefits in all enterprise applications • Improved communication • Employee mobility • Faster response • More productivity • Competitive advantage • Additional factors contribute to Return on Investment • Leverage wireless LAN and IP telephony infrastructure • More efficient utilization of network resources • Reduce cost of telephone moves, adds and changes
