Licensed Points To Point Microwave Service
Licensed Microwave service has been used since the 1960s to transmit very large amounts of data. The AT&T Long Lines coast to coast backbone in the USA was largely carried over a chain of microwave towers. These systems have been largely using 3700-4200 MHz and 5000-6200 MHz. The 5 GHz band was even known as the "common carrier" band. This service typically was prohibitively expensive to be used for Local Loop, and was used for backbone networks. In the 80s and 90s it flourished under the growth of cell towers. This growth spurred research in this area, and as the cost continues to decline, it is being used as an alternative to T-1, T-3, and fiber connectivity.

Famous quotes containing the words points, point, microwave and/or service:
“The two great points of difference between a democracy and a republic are: first, the delegation of the government, in the latter, to a small number of citizens elected by the rest; secondly, the greater number of citizens and greater sphere of country over which the latter may be extended.”
—James Madison (1751–1836)
“How oft when men are at the point of death
Have they been merry! which their keepers call
A lightning before death: O, how may I
Call this a lightning? O my love! my wife!
Death, that hath sucked the honey of thy breath,
Hath had no power yet upon thy beauty:
Thou art not conquered; beauty’s ensign yet
Is crimson in thy lips and in thy cheeks,
And death’s pale flag is not advanced there.”
—William Shakespeare (1564–1616)
“The New Age? It’s just the old age stuck in a microwave oven for fifteen seconds.”
—James Randi (b. 1928)
“The summer soldier and the sunshine patriot will, in this crisis, shrink from the service of his country; but he that stands it NOW deserves the love and thanks of man and woman.”
—Thomas Paine (1737–1809)
