Comparison to Wired Net.
Wired Networks
-high bandwidth -low bandwidth variability -can listen on wire -high power machines -high resource machines -need physical access(security) -low delay connected operation |
Mobile Networks
-low bandwidth -high bandwidth variability -hidden terminal problem -low power machines -low resource machines -need proximity -higher delay disconnected operatio |
Why Go Mobile?
- Enable anywhere/anytime connectivity
- Bring computer communications to areas without pre-existing infrastructure
- Enable mobility
- Enable new applications
- An exciting new research area

The Technology Infrastructure
Wireless information systems are computing systems that provide the ability to compute and communicate anywhere and anytime. A number of terms have been used in the literature to describe such systems, including wireless computing, ubiquitous computing, nomadic computing and decoupled computing.Wireless networks communicate by modulating radio waves or pulsing infrared light. Wireless communication is linked to the wired network infrastructure by stationary transceivers. The area covered by an individual transceiver's signal is known as a cell. Cell sizes vary widely: for example, an infrared transceiver has a range of a few meters, and a satellite beam can cover an area more than 400 miles in diameter.
