Telecommunications in Ethiopia is a monopoly in the control of Ethio telecom, formerly the Ethiopian Telecommunications Corporation (ETC). As of 2012, 20.524 million cellular phones and 797,500 main line phones were in use.[1] The telephone system in Ethiopia consists of open wire and microwave radio relay systems adequate for government use. Domestic systems are open wire; microwave radio relay; radio communication in the high frequency, very high frequency, and ultra high frequency; two domestic satellites provide the national trunk service. International systems are open wire to Djibouti and Sudan; microwave radio relay to Djibouti and Kenya; and satellite earth stations are 3 Intelsat (1 Atlantic Ocean and 2 Pacific Ocean).[1] The Ethiopian dial plan changed on 17 September 2005. City codes (i.e., internal prefixes) changed from two digits to three (or, from outside Ethiopia, one digit to two) [...More Info...] [...Related Items...] |

Antenna (radio)
In radio engineering, an antenna is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver.[1] In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be amplified. Antennas are essential components of all radio equipment. An antenna is an array of conductors (elements), electrically connected to the receiver or transmitter. Antennas can be designed to transmit and receive radio waves in all horizontal directions equally (omnidirectional antennas), or preferentially in a particular direction (directional, or high-gain, or “beam” antennas) [...More Info...] [...Related Items...] |

CDMA2000
CDMA2000 (also known as C2K or IMT Multi‑Carrier (IMT‑MC)) is a family of 3G[1] mobile technology standards for sending voice, data, and signaling data between mobile phones and cell sites. It is developed by 3GPP2 as a backwards-compatible successor to second-generation cdmaOne (IS-95) set of standards and used especially in North America and South Korea.
CDMA2000 compares to UMTS, a competing set of 3G standards, which is developed by 3GPP and used in Europe, Japan, and China.
The name CDMA2000 denotes a family of standards that represent the successive, evolutionary stages of the underlying technology
