Over the past ten years there has been one of the greatest levels of change that has ever taken place. This is the manner in which communications take place, and the impact it has had upon the way business is carried out. It is not only business that has seen major change. Personal communication has also been through huge change. The Internet is now a significant part of life in all areas, and it is becoming ever more significant.

The Internet, however, is just one part of the communications revolution. Perhaps the biggest change has been in personal communications with the cell phone. Today cell phones have massive coverage and are used by large percentages of the population. New forms of communication have come about with the cell phone, in particular using text messages. The key development in business communications brought about by the cell phone is one never needs to be out of contact. The cell phone created the unwired communication world.

The Internet for many years was limited to being a wired form of communication, either through permanent or dial up connections. The cell phone started the change in this allowing limited Internet access using the cell phone as an Internet modem. This however was not as fast as using a dial up wired approach. The Internet however became a limited unconnected medium with WiFi technology using wireless technology for broadband high-speed Internet access. By limited I mean that it is limited to operation within reach of a WiFi hotspot or within a closed office environment. Such hotspots are rapidly appearing in hotels, coffee shops, airports, and certain travel and retail centers.
