Networks make it easy to establish ad hoc collaborating communities of people and computing devices. They configure and reconfigure themselves automatically, as nodes appear, migrate, and disappear. This makes them easier to maintain than before, when networks were tuned largely for static wired topologies. Local networks connect seamlessly with each other, with satellite and terrestrial networks, and with a large number and variety of physical devices that can be used to monitor and control the physical world.

The demand for network technologies and communications is large and growing rapidly. Networking should be on-demand, with whomever or whatever they want, regardless of time or location. To meet these requirements, industry has invested heavily in a variety of wireless and wireline communications technologies, each with its own strengths and weaknesses. In recent times, we have seen the emergence of 3G and 4G, WiFi and WiMax, Bluetooth and Zigbee, Ultrawideband and TV-band, Powerline and Free space optical.
