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:
“He is the best sailor who can steer within the fewest points of the wind, and extract a motive power out of the greatest obstacles. Most begin to veer and tack as soon as the wind changes from aft, and as within the tropics it does not blow from all points of the compass, there are some harbors which they can never reach.”
—Henry David Thoreau (1817–1862)
“There are neither good nor bad subjects. From the point of view of pure Art, you could almost establish it as an axiom that the subject is irrelevant, style itself being an absolute manner of seeing things.”
—Gustave Flaubert (1821–1880)
“The New Age? It’s just the old age stuck in a microwave oven for fifteen seconds.”
—James Randi (b. 1928)
“You had to face your ends when young
‘Twas wine or women, or some curse
But never made a poorer song
That you might have a heavier purse,
Nor gave loud service to a cause
That you might have a troop of friends.”
—William Butler Yeats (1865–1939)
