The PatientKeeper's Mobilizer Platform is architected such that PDAs communicate with enterprise servers regardless of the transportation mechanism. The platform supports the connectivity technology available to the end-user. Supported technologies include Bluetooth wireless PAN, 802.11b wireless LAN, and CDMA.

In addition, PatientKeeper supports handhelds in settings where wireless transport is unavailable or unwanted. This capability is sometimes referred to as "always ready" operation. In this scenario, connectivity is accomplished through network synchronization cradles and infrared stations.

Taken together, PatientKeeper takes advantage of wireless transport when it's available and operates effectively when wireless is unavailable. This dual capability is key for many reasons, including:

• Users may wish to enjoy the many benefits of mobile computing, but are not yet ready to embrace wireless infrastructure. With our framework, they can use PatientKeeper today and add wireless functionality in the future.
• · Institutions that have embraced wireless infrastructure must contend with wireless blackout zones (shielded radiology rooms, elevators, basements, etc.). PatientKeeper supports settings where wireless transport is unavailable.
• End-users require fast response times and must be insulated from latency/lag when wireless performance is poor.

Finally, transmission of data to and from the PDA can be secured with Elliptical Curve Cryptography (ECC) encryption.
