Project Overview Primary focus to support the clinical agenda Promote safety for patients and staff Monitor Mobile Assets Providing information at point of use HIPAA Compliant Partnership with vendor Rapid delivery schedule Targeted solution Concept investment by OMH and Vendor Available off the shelf technology and software
History of Wireless
Wireless Lan at OMH Introduced November of 2001
Communication protocol 802.11bUnsecured for confidential
information Signal leak of 3/8 mile outside of building Flexible options for infrastructure Solution for confidential information V-LAN with VPN for encryption
History of Wireless
Wireless WAN at OMHBegan July of 2001
Concept of mobile computing for staffNew direction for OMH and
vendor technology based on cell modem Compaq’s iPAQ Windows CE 3.0 OMH infrastructure difficult to integrate Choices and options have changed
Wireless Hardware Platform

Technical Overview for Security
HIPAA Compliant – Privacy and Security iPAQ / Tablet Protection - signature signon,
RSA, password and combination of all three McAfee Anti-Virus Encryption for Internet traffic is provided by a
VPN or SSL Interfaces to standard OMH security protocol Hard Drive encryption iPAQ - sqlserver
database encryption Tablet – encryption Safeguard Easy

Downside of Wireless WAN Narrow bandwidth for cell connection Need to cradle for maintenance Coverage -too many dead spots If not CDPD then it’s expensive Cell service start-up is time consuming Anything but Web-based tough to run Battery time is short Re-connect options are manual Hardware is portable so are the problems
Downside of Wireless LAN
Currently 802.11b is unsecured for confidential information
OMH building not configured for wireless Hardware becomes portable so do the
problems Must use VPN or other method for strong
encryption – 128bit or higher
Upside of Wireless WAN
Allows staff to communicate with others while in the field especially during emergencies
Increases the safety/productivity of staff Allows real-time management of
resources from Central Office Web Based Application best choice Client/Server possible although difficult
Upside of Wireless LAN
Reduced effort for cabling Client/server applications work fine Computer support now mobile
no longer office bound Messages and information at your
fingertips Not much different from wired desktops
Closing RemarksProject is technology neutral Use of Corporate partnershipLeverages investment in existing OMH
infrastructure Technology is transportable Short development cycle with focusBase software components are replaceable
