Steps for Successful Implementation

PDA Evaluation

Mobile Deployment Strategy

Vision

Why PDAs and Wireless?

Immediate need for Administration to retrieve E-mail remotely

Students showing up with PDAs and wireless ethernet cards and requesting support

Growing interest among faculty and researchers for the possible uses of PDAs for data gathering

Faculty interest in evaluating how the PDA may be used in the classroom

Problems/Solutions

Windows Devices (Outlook CE does not support SSL Mail)

No CE Client that works well with CorporateTime Calendar

Sierra Wireless Aircard is slow (19.2 K)

Browsing Web was painfully slow (even with Cisco Ethernet card) Some websites were designed for CE

Cannot Hotsync using IMAP Eudora Mail Client – only POP

ActiveSync connection via USB does not immediately disconnect after selecting `Disconnect` on the iPAQ

Need to forward mail from Lehigh account to RIM 950 Cingular account (need to maintain 2 accounts).

Positives

Microsoft ActiveSync worked very well (upgraded to Windows XP with no problem)

Sierra Wireless 300 card could be used for laptops as well as iPAQ. (laptop drivers are downloadable)

Cisco card installed seamlessly in iPAQ as well as laptop. (CE drivers are downloadable)

Sierra Wireless card software installed on Windows ME/2000/XP laptop transparently.

Eudora has E-mail Client for Palm devices that supports SSL (setup ISP mail server as outgoing)
