Hierarchical cell structure ("HCS") used in mobile telecommunication means splitting of cells. This type of cell structure allows the network to effectively use the geographical area and serve an increasing population.
The large cell (called a "macro cell") is rearranged to include small cells in it called micro and pico cells. The cricket stadium/exhibition ground can be a micro cell and a multi storied building can be a pico cell within the large cell. The micro/pico cell is allocated the radio spectrum to serve the increased population. The User Equipments (UEs) going out of the pico/micro cells are allowed to reselect the larger cell.
The HCS cells are given priorities from 0-7 where 0 is the lowest priority and 7 the highest. The cells close to the serving cell are given highest priority. The mobiles in high mobility prioritise to reselect to the lower priority cells to avoid continuous reselections.
Microcells can add localized capacity within Macro cell.
Famous quotes containing the words hierarchical, cell and/or structure:
“Authority is the spiritual dimension of power because it depends upon faith in a system of meaning that decrees the necessity of the hierarchical order and so provides for the unity of imperative control.”
—Shoshana Zuboff (b. 1951)
“It is plain that there is no separate essence called courage, no cup or cell in the brain, no vessel in the heart containing drops or atoms that make or give this virtue; but it is the right or healthy state of every man, when he is free to do that which is constitutional to him to do.”
—Ralph Waldo Emerson (1803–1882)
“The structure was designed by an old sea captain who believed that the world would end in a flood. He built a home in the traditional shape of the Ark, inverted, with the roof forming the hull of the proposed vessel. The builder expected that the deluge would cause the house to topple and then reverse itself, floating away on its roof until it should land on some new Ararat.”
—For the State of New Jersey, U.S. public relief program (1935-1943)
