8 Consider what Mobile computing actually is Consider what Mobile computing actually is It is more than a laptop connected to a phone network It is more than a laptop connected to a phone network Which part is actually mobile Which part is actually mobile The deviceThe device Tracking systems on cars Tracking systems on cars Allows connection at any time, anywhere Allows connection at any time, anywhere The userThe user Allowing access to essential information Allowing access to essential information Email, Internet, Virtual LAN Email, Internet, Virtual LAN Available anywhere anytime, anyone ??? Available anywhere anytime, anyone ???

9 Mobile Computing When would use different types of mobile technology When would use different types of mobile technology This table considers a Laptop and a business man This table considers a Laptop and a business man At some stage they will use all methods of connecting to gain information At some stage they will use all methods of connecting to gain information The challenge is to integrate all of these technologiesThe challenge is to integrate all of these technologies The best one being chosen at the best timeThe best one being chosen at the best time MobileWirelessFixed At work In a hotel In an historic building
