ABSTRACT
With the development of inventions like the radio and the wireless telephone, the whole world is becoming, in a very literal sense, a whispering-gallery.
Irving Babbitt, scholar and author, 1865-1933
The proliferation of laptop computers, notebooks, PDAs, Blackberrys and other portable devices has significantly added to business efficiency, portability and flexibility. To augment and enhance data communications and maximize the utility of these devices, wireless networks of various kinds have gained widespread acceptance and popularity.
