   The transmitting signal from Macro Base Station (MBS) weakens quickly once the MBS signal reaches indoors. Femtocells provide a solution to the difficulties present in macrocell-based system. Thus, Femto Base Station (FBS) network coverage is one of the prime concerns in indoor environment to get good quality of service (QoS).

   en.wikipedia.org/wiki/Cell_site

   Cellular lattice tower A cell tower in Peristeri, Greece. A cell site, cell phone tower, cell base tower, or cellular base station is a cellular-enabled mobile device site where antennas and electronic communications equipment are placed (typically on a radio mast, tower, or other raised structure) to create a cell, or adjacent cells, in a cellular network.

5. Okumura model - Wikipedia

   en.wikipedia.org/wiki/Okumura_Model

   Okumura developed a set of curves giving the median attenuation relative to free space (A mu), in an urban area over a quasi-smooth terrain with a base station effective antenna height (hte) of 200 m and a mobile antenna height (hre) of 3 m. These curves were developed from extensive measurements using vertical omni-directional antennas at both ...

6. Hata model - Wikipedia

   en.wikipedia.org/wiki/Hata_model

   The Hata model is a radio propagation model for predicting the path loss of cellular transmissions in exterior environments, valid for microwave frequencies from 150 to 1500 MHz. It is an empirical formulation based on the data from the Okumura model , and is thus also commonly referred to as the Okumura–Hata model . [ 1 ]

7. Line-of-sight propagation - Wikipedia

   en.wikipedia.org/wiki/Line-of-sight_propagation

   "sectorized" antennas at the base stations. Instead of one antenna with omnidirectional coverage, the station may use as few as 3 (rural areas with few customers) or as many as 32 separate antennas, each covering a portion of the circular coverage. This allows the base station to use a directional antenna that is pointing at the user, which ...
