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
PDA Evaluation Process
Identified and Acquired PDAs, ISPs and Wireless Cards/Devices
Developed Evaluation Criteria
Identified Potential Uses
Identified Next Steps

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)
Wireless Connectivity
Original discussions/conclusions Purchase of Hardware Map of Corridor CISCO and Compaq cards Access by phone service Access by PDA
Uses in Course Design
School of Education General Requirements
School of Industry and Technology Avantgo Server-based instruction
Uses in Course Design (cont.)
School of Medicine Transfer of Patient Data Transfer of Billing Information
