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

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 Remarks

Project is technology neutral Use of Corporate partnershipLeverages investment in existing OMH

infrastructure Technology is transportable Short development cycle with focusBase software components are replaceable
