Integrated Digital Enhanced Network - History

History

The iDEN project originally began as MIRS (Motorola Integrated Radio System) in early 1991. The project was a software lab experiment focused on the utilization of discontiguous spectrum for GSM wireless. GSM systems typically require 24 contiguous voice channels, but the original MIRS software platform dynamically selected fragmented channels in the radio frequency spectrum in such a way that a GSM telecom switch could commence a phone call the same as it would in the contiguous channel scenario. The original MIRS System was renamed IDEN in 1994 by Roger Cameron Wood, a young engineering program manager leading the product development effort who also gave the handsets their distinctive industrial design, group software features, and "chirp" audio cue.

Famous quotes containing the word history:

    As I am, so shall I associate, and so shall I act; Caesar’s history will paint out Caesar.
    Ralph Waldo Emerson (1803–1882)

    Most events recorded in history are more remarkable than important, like eclipses of the sun and moon, by which all are attracted, but whose effects no one takes the trouble to calculate.
    Henry David Thoreau (1817–1862)

    To care for the quarrels of the past, to identify oneself passionately with a cause that became, politically speaking, a losing cause with the birth of the modern world, is to experience a kind of straining against reality, a rebellious nonconformity that, again, is rare in America, where children are instructed in the virtues of the system they live under, as though history had achieved a happy ending in American civics.
    Mary McCarthy (1912–1989)
