There are 51 MTAs, 493 BTAs and 175 EAs in the United States. The Advanced Wireless Services (AWS) bands, auctioned in the summer of 2006, were for 1,710–1,755 MHz, and 2,110–2,155 MHz. The spectrum was divided into blocks: A blocks were for Cellular Market Areas, based on existing cellular (1G) licenses, and were 2 × 10 MHz.
Cellular frequencies. Cellular frequencies are the sets of frequency ranges within the ultra high frequency band that have been assigned for cellular-compatible mobile devices, such as mobile phones, to connect to cellular networks. [1] Most mobile networks worldwide use portions of the radio frequency spectrum, allocated to the mobile service ...

v. t. e. A cellular network or mobile network is a telecommunications network where the link to and from end nodes is wireless and the network is distributed over land areas called cells, each served by at least one fixed-location transceiver (typically three cell sites or base transceiver stations ). These base stations provide the cell with ...

A cellular network is a network of handheld mobile phones (cell phones) in which each phone communicates with the telephone network by radio waves through a local antenna at a cellular base station (cell site). The coverage area in which service is provided is divided into a mosaic of small geographical areas called "cells", each served by a ...
Coverage noticer. A coverage noticer is a device that beeps (or vibrates) when in a zone that lacks coverage ( white spot ). This is fundamental for critical services (security, emergency and so on). When the user goes to a covered area, the noticer ceases beeping. Similarly coverage maps are often used to visualize coverage, these are produced ...
Systems that efficiently use the available spectrum have been developed e.g. the GSM system. Bernhard Walke defines spectral efficiency as the traffic capacity unit divided by the product of bandwidth and surface area element, and is dependent on the number of radio channels per cell and the cluster size (number of cells in a group of cells):
