Advanced Mobile Phone System Frequencies in the range of 800 and 900 Mhz where half of the frequency range is allocated to sending of voice information and the other half for receiving. The frequency spectrum is then sub divided into "channels" by using FDMA - Frequency Division Multiple Access. Each channel is assigned to only one cellular phone at a time.
Abbreviation for dvanced obile hone ystem. AMPS is a standard system for analog signal cellular telephone service in the United States and is also used in other countries. It is based on the initial electromagnetic radiation spectrum allocation for cellular service by the Federal Communications Commission (FCC) in 1970. Introduced by AT&T in 1983, AMPS became and currently still is the most widely deployed cellular system in the United States.
Stands for Advanced Mobile Phone System, which is the most common type of First Generation analog cell phone network. Because analog phones are suited for voice rather than data communications, AMPS networks are rapidly being supplanted by digital wireless networks. Operates in the 800 MHz frequency band and uses FDMA technology.
If you are looking to buy or already own a cellular phone, then this acronym should mean something to you. The letters AMPS, otherwise known as analogue, stand for Advanced Mobile Phone System. This is older cell phone technology, dating back to the early 1980s. The AMPS uses radio wavelengths to transmit telephone calls.
Abbreviated as "Advanced Mobile Phone Service"] The analog cellular phone standard first introduced by AT&T in 1983. AMPS phones operate in the 800 to 900 Megahertz (MHz) radio spectrum. The term is "cell" phone because the signals are sent from radio transmitters that cover a broadcast area known as a cell.
AMPS stands for Advanced Mobile Phone System. AMPS was the first analog system used for providing cellular phone service. It works in the 800MHz frequency range. AMPS was introduced in 1983. Analog works by converting sound into electrical energy which is then transferred to the far end. The signal being transmitted is analogous (similar) to the original signal and is not digitized. Analog offers one voice conversation per voice channel.
Advanced Mobile Phone Service. The term used by AT&T's Bell Laboratories (prior to divestiture in 1984) to refer to its cellular technology. The AMPS standard has been the foundation for the industry in the U.S., although it has been slightly modified in recent years.
Advanced Mobile Phone Service. The analog wireless transmission standard (technology) deployed in the 1980s in the United States and Canada. AMPS operates at 800 MHz. See also N-AMPS (Narrowband AMPS).
Advanced Mobile Phone System AMPS concerns to networks of the first generation, that is uses analog (without digital coding) type of a voice transfer. Now we shall not concern advantages and lacks of analog systems of communication(connection) in comparison with digital - we shall notice (and we shall more in detail consider a little bit below), that there is digital variant AMPS - DAMPS (Digital AMPS).
Advanced Mobile Phone Service, the first-generation, analog cellular network that arrived in the United States in the 1980s. While digital networks have taken over most populated areas in the United States, AMPS still covers rural areas that CDMA and GSM can't reach.
Acronym for Advanced Mobile Phone Service--the standard used for analog cell phone service in the United States. The service was first launched in 1983, then was replaced by digital services (i.e. CDMA and TDMA).
A standard system for analog cellular telephone service in the United States, and it also is used in some Latin American and Asia Pacific countries. It is based on the initial spectrum allocation for cellular service (in the 800 MHz band) by the FCC in 1970. Introduced by AT&T in 1983, AMPS became and currently still is the most widely deployed cellular system in the United States.
Advanced Mobile Phone Service (AMPS). The standard AMPS for analog cellular telephones operates in the 800 MHz band and uses frequency spacing and frequency-modulated transmission to separate user transmissions.
Advanced Mobile Phone Service. The standard for analog cellular telephones, which uses a frequency-modulated transmission and frequency spacing to separate user transmission. AMPS operates in the 800 MHz band.
Advanced Mobile Phone System. The North American analog cellular phone system. The spectrum allocated to AMPS is shared by two cellular phone companies in each area or region (geographic market). This system was deployed during the 1980s and today it and its variants represent nearly 85% of the cellular voice systems installed throughout the world.
Analog cellular service. The original cellular mobile phone air interface, which uses conventional radio frequency modulation, and has no digital compression. Although call quality is inferior, battery life suffers, and few value-added services are compatible, AMPS still is used widely in rural and developing areas, due to the high-range of signals, and the low cost of maintaining existing systems. CDMA - C ode ivision ultiple ccess. A digital method for simultaneously transmitting signals over a shared portion of the spectrum by encoding each distinct signal with a code chip. Terminals receive the aggregated signal from the tower, and use specific codes to unbundled the signals. CDMA devices are noted for their excellent connection quality and long battery life.
The analog cellular standard, AMPS operates in the frequency range between 800 and 900 Megahertz. The signals received from a transmitter cover an area called a cell. This technology has since been updated with digital service.
Advanced Mobile Phone Service. Analog cellular standard operating in the frequency range of 1800MHz with a bandwidth of 30kHz. First established cellular standard in the world. Analog cellular subscribers in North America are served by AMPS.
AMPS is used in North and South America. It is also the most common system in the Asia/Pacific region and can be found in countries such as Australia, Hong Kong, New Zealand, South Korea, Singapore, Taiwan, Thailand and Israel.
Advanced Mobile Phone Service. A first-generation frequency division duplex analog radiotelephone standard used primarily in North America, Central America and South America. AMPS uses a total of 50 MHz of spectrum: 25 MHz at 824-849 for uplink transmission and 25 MHz at 869-894 MHz for downlink transmission, using 30 kHz channel separation. D-AMPS is the digital version of the standard.
Advanced Mobile Phone Service, the first-generation, analog cellular network that arrived in Australia in the 1987. It was phase out in favour of digital networks and fully closed in 2000. Telstra replaced the AMPS network with a CDMA network that still covers regional and rural areas.
Advanced Mobile Phone Service (AMPS) is a first-generation analog, circuit-switched cellular phone network. Originally operating in the 800 MHz band, service was later expanded to include transmissions in the 1900 MHz band, the VHF range in which most wireless carriers operate. Because AMPS uses analog signals, it cannot transmit digital signals and cannot transport data packets without assistance from newer technologies such as TDMA and CDMA.
Advanced Mobile Phone Service. Analogue cellular telephone technology is used mainly in the US. Operates in the 800Mhz band frequency. This was the original American analogue cellular radio system used by AT&T (the digital enhancement was originally called D-AMPS, and is now known as TDMA). About 40% of Latin American and 25% of North American subscribers are on AMPS. The bulk of AMPS migration is to CDMA-One and TDMA.
Advanced Mobile Phone Service, the first-generation, analog cellular network that arrived in the 1980s. While digital networks have taken over most populated areas, AMPS still covers rural areas in some countries (eg the US) that CDMA and GSM can't reach.
The original standard specification for analog systems. Operates in the frequency range of 800 MHz, with a bandwidth of 30kHz. Used primarily in North America, Latin America, Australia and parts of Russia and Asia.
Also known as Amperes. This is the rate at which electrons flow in a wire. The units are coulombs per second, or since an electron has a charge of 1.602 x 10-19 coulombs, an amp is 6.24 x 10+18 electrons per second. Think of marbles rolling through a tube. If 6.24 x 10+18 pass by in 1 second you wuld have an amp of marbles.
Unit of measurement. Represents the current or flow rate of electricity. Most electric powered scooters will come with a battery system that will show the current in amps, it is usually shown after the voltage as amp hours (Ah).
Administrative Monetary Penalty System. The Administrative Monetary Penalty System (AMPS) is a civil penalty regime that secures compliance with Customs legislation through the application of monetary penalties. AMPS largely replaces the use of seizure and forfeiture provisions for technical infractions. AMPS applies to contraventions of the Customs Act and the Customs Tariff and the regulations there under, as well as contraventions of the terms and conditions of licensing agreements and undertakings.
