4. doc.: IEEE 802.15- Submission, Configuration Issues for Wireless Medical Networks Pre-Install for an Isolated Network Site survey and network design Existing systems? Interference Capacity Physical structure considerations Pre-Install for Shared Infrastructure Existing SSIDs Existing security Existing capacity Physical structure considerations

5. doc.: IEEE 802.15- Submission, Configuration Issues for Wireless Medical Networks FDA risk mitigation testing Manufacturers do not test medical devices on an open network, rather on a dedicated network with only the devices under test Impossible to predict all risk associated with adding specific medical devices to an integrated HCIT infrastructure

6. doc.: IEEE 802.15- Submission, Configuration Issues for Wireless Medical Networks Go Live Zero dead spots Zero downtime Zero interference Failure to achieve this goal can result in significant patient harm or death in as little as 2 minutes

7. doc.: IEEE 802.15- Submission, Maintenance Issues for Wireless Medical Networks Life span for medical devices exceeds infrastructure Medical device lifespan up to 15 years 3-5x longer than infrastructure IT support model: standardize hardware, with controlled images √Nearly impossible with medical devices Maintenance and support burden increases with every change Manufacturers must support devices for 7 years after last sale

8. doc.: IEEE 802.15- Submission, Maintenance Issues for Wireless Medical Networks Turf wars Medical device support personnel frequently denied access to infrastructure Medical device support personnel frequently unaware of network changes, find out upon failure

9. doc.: IEEE 802.15- Submission, Maintenance Issues for Wireless Medical Networks Upgrading a wireless infrastructure FDA 510k approval necessary for upgrades if changes affect form, fit, and function If form, fit, and function is not changed, V&V is performed by the manufacturer V&V testing consumes valuable resources
