© 2005 University of Chicago Hospitals 11 Joint Wireless/ICS Meeting The Wireless Utility in Healthcare Does a Wireless Utility really provide the solution hospitals need? »Questions we asked ourselves as we were assessing our position in UCH’s new Comer Children’s Hospital two years ago: – Should we deploy multiple single-point, in-building wireless systems? – Each requiring its own equipment and distribution infrastructure, technology standards and communication protocols, and maintenance, management and operational overhead OR –Was the technology ready today to build a shared wireless distribution utility? –We chose the latter
© 2005 University of Chicago Hospitals 12 Joint Wireless/ICS Meeting Point solutions are more costly and difficult to manage than enterprise solutions. An HVAC analogy… You wouldn’t cool your building with individual window units… … you would build a single HVAC infrastructure – an in- building utility. The Wireless Utility in Healthcare
© 2005 University of Chicago Hospitals 13 Joint Wireless/ICS Meeting The Wireless Utility in Healthcare In determining what we wanted out of a Wireless Utility, the UCH IS team established the following technical goals: »Build a shared, broadband wireless infrastructure »Provide consistent, reliable radio frequency (RF) coverage »Minimize interference potential with hospital biomedical equipment »Ensure the utility is managed and secure »Guarantee predictable, low total cost of ownership »Provide flexibility for new services and applications »Ensure it is open…make it protocol and service provider independent
© 2005 University of Chicago Hospitals 14 Joint Wireless/ICS Meeting The Wireless Utility in Healthcare UCH Wireless Utility Design »Reliable wireless communications (designed for > 95% coverage) using a single infrastructure that will support current, as well as future, wireless voice and data services »Ability for 2-way radio (450 MHz), Paging (900 MHz) and PCS/Cellular Carriers (800 and/or 1900 MHz) to distribute their wireless services at their licensed frequencies throughout the facility »Provide uniform coverage for wireless LANs (802.11) for immediate and future installations »Ability for UCH to add capacity at any time without modification to the system »Ability to operate the system with little maintenance, due to the passive design »Ability to add any current and anticipated frequency between 400 MHz and 5 GHz
