The Wireless Revolution : Where it is headed and what it means to the Digital Firm

The integration of microcosm and telecosm in a series of multimedia sectors ranging from personal intelligent communicators to video teleputers to digital films and publishing is presently the impetus of world economic growth . Such a new era of computer communications have thronged into particularly in two dimensions-the fibersphere and the atmosphere [banner_entry_middle]

. The fibersphere includes the domains of all-optical networks , having the potentiality of communication power , the bandwidth and error rate enhanced by factors in the millions . The communication potentiality of the fibersphere is seen to be 1000 times greater than all the currently applicable frequencies in the air and so drastically error-free that it caters to a quite new model of wired telecommunications . Presently the atmosphere is offering links as mobile and ever-present . It thus caters to the formation of a completely new model of wireless networks (Glider , 1993

In 1865 the Scottish Physicist James Clerk Maxwell discovered the electromagnetic spectrum . Maxwell ‘s rainbow reaches from the extremely low frequencies applied for establishment of communication with submarines be means of the frequencies used in radio , television and cellular phones , on up to the frequencies of infrared used in TV remotes and fiber optics and further to visible and ultraviolet light and X-rays . In case of integration , Maxwell reduced he entire spectrum to just four equations in vector calculus . He proved that all such radiations move at the speed of light , in other words , the wavelength times the frequency is equivalent to the speed of light . Such equations have become the pivot around which the whole information world presently revolves . In reality all electromagnetic radiations can hold information and the higher the frequencies , the more room they entail for bearing information . In a practical matter , however , communications engineers have targeted at low , thronging the frequencies at the bottom of the spectrum , involving much less than one percent of the However , the huge expansion of the wireless communications predicted by Sculley , however , will necessitate use of higher frequencies far up Maxwell ‘s rainbow . In 1948 , the transistor was invented by Shockley and the information theory invented Claude Shannon that underlies all modern communications . At the first instance information theory is difficult for non-mathematicians , but computer and telecom executives are required to concentrate on only a few crucial concepts . While finding out the quantum of information that is possible to be sent down a noisy channel Shannon indicated that engineers can opt between narrowband high-powered solutions and broadband low powered solutions . Presuming that the adoptive bandwidth is scanty and costly , most wireless engineers have strived to economize on it . Similar to the policy of talking louder in a crowded room for getting a message , the noisy channel can be overcome by more powerful signals . Engineers therefore initiated a strategy of long and strong : long wavelengths and… [banner_entry_footer]
