pico radio cell

In cellular mobile communications networks, the intelligent radio cells, smart cells, are designated according to cell size. A distinction is made between femtocells, picocells, microcells and macrocells. Picocells and femtocells are small radio cells, also known as small cells, with an extension of 50 to 200 meters. They are primarily used in in-house applications, in buildings and grounds, and in urban areas.

The classification of pico radio cells

Pico cells are divided into flexible, semi-flexible and dipole radio cells.

In a flexible radio cell, all stations are usually equal transmitters and receivers. All stations can be moved as required within this radio cell without any cable interfering or restricting them. This means that the individual stations in this radio cell are completely flexible and mobile. The only limitation is the size of the radio cell. This is limited by the transmitting power of the transmitter and the sensitivity of the receivers.

Use and expansion of the various radio cells

Use and expansion of the various radio cells

In semi-flexible radio cells, a central module forms the heart of a radio cell. Several peripheral modules are connected to the central module via wireless links. The individual stations are connected to the peripheral modules via a cable. All stations must be grouped around the individual peripheral modules and wired to them.

The opposite of flexible radio cells are dipole radio cells. In essence, dipole radio cells correspond to wireless point-to-point connections in the form of PP directional radio. They are used, for example, to establish a network connection between two buildings or two LAN segments quickly and inexpensively. The distances between the two poles can range from 100 meters to eight kilometers. The main application area of dipole radio cells are wireless remote bridges or modems. Such bridges or modems are able to connect Ethernet and Token Ring.
