Mobile Computing
• Using:
– small size portable computers, hand- held, MNC, and
other small wearable devices,
• To run stand-alone applications (or access
remote applications) via:
– wireless networks: IR, BlueTooth, W-LANs, Cellular,
W-Packet Data networks, SAT. etc.
• By:
– nomadic and mobile users (agents, trains, cars, cell
phones, ….)
Fantastic Breakthrough Technology
• Wireless communication networks
– multiple networks “covering” the globe
– wold-wide deregulation and spectrum auctions
– standard communication systems and air link
interfaces
• Portable information appliances
– laptops, notebooks, sub-notebooks, and MNCs
– hand-held computers
– PDAs and Smartphones
• Internet:
– TCP/IP & de-facto application protocols
– ubiquitous web content
New Forms of Computing

summary
• Mobile computing has severe limitations
- however, it is far from impossible, and
technology improves all the time
• Lots of challenges
- some have (good) solutions, many others are
still waiting to be solved
