Wireless LAN’s

Wi-Fi or wireless fidelity – specifies the
interface between a wireless client and a base
station or between two wireless clients.


Programming on a Handheld
Device
Screen Size must
be taken into
consideration
 Graphics?
 Platform?
 Program from top
to bottom

42
Considerations
Maximize the speed
 Watch for memory issues
 Design/Ease of data entry for the user

43
Why program?
 Custom
design
applications, including
wireless, rather then
"off the shelf
packages". Each
application is "one of a
kind".
