The Everpresence of Wireless Communication

Wireless communication is simply the transfer of data between two points that are not connected by a physical wire.

The most common wireless technologies use radio waves. The range of distances radio waves travel goes from very short, such as a few meters for television, to very long indeed, such as the millions of kilometers traveled in deep-space radio communications.

Examples of applications of radio wireless technology include GPS, garage door openers, wireless computer peripherals, such as mice, keyboards and headsets, satellite television, broadcast television, cordless telephones, two-way radios, and radio receivers themselves. The two applicaions of wireless communicaiton we are most interested in are cellular telephones, and the wireless networking of laptops and PCs.

Approach to this assessment statement # 2:

Social & Economic Effects

And, so, this is the social and economic effects of wireless networks as they relate to the S/E Teaching Note above: "S/E wireless networks have led to changes in working patterns, social activities and raised health issues."

With this, yes, you will be talking about the general concept of us being hooked to our computers too much now-a-days, but make sure to focus on social and environmental effects of wireless networks in this wider problem.

A. Changes in Working Patterns:
