Digital Advanced Mobile Phone System. An American standard for digital mobile telephony used primarily in North America, Latin America, Australia and parts of Russia and Asia, now commonly referred to as TDMA.
Has been renamed TDMA (Time Division Multiple Access). TDMA is a digital mobile phone network that operates in the US, Latin America, New Zealand, parts of Russia and Asia Pacific. Ericsson's TDMA mobile phones also work on AMPS networks. Back to the top.
Referred to as TDMA, D-AMPS is used by wireless network operators in North and South America. TDMA occupies the same amount of spectrum per analog channel (30 KHz) and is used in place of an analog channel to increase the number of calls to 4 or 5 per channel depending upon the implementation. Also called ANSI-136.
This system was developed as a digital enhancement to the AMPS system via the use of dual-mode phones. In the US these phones are able to switch between the AMPS analog and TDMA digital networks, giving the user the benefit of digital in TDMA areas and the widespread coverage of analog in AMPS areas.
Digital enhancement of AMPS, designed for migration to 2G. D-AMPS uses the TDMA transmission standard in the frequency range around 1900 MHz. DSL (Digital Subscriber Line â€“ DSL or xDSL): This goes under various brandnames in different countries. It is better known as Jetstream in New Zealand, where Telecom has been reluctant to provide it to its full potential. It is basically a method of using copper telephone wires for high-speed broadband communications.
(Digital Advanced Mobile Phone System) Earlier designation of American standard for digital mobile telephony used primarily in North America, Latin America, Australia and parts of Russia and Asia. Now known as TFMA. See also TDMA and IS-136.
Digital AMPS, the digital wireless standard widely used throughout the Americas, Asia Pacific and other areas. D-AMPS services can be introduced in the 800 MHz and 1900 MHz frequency bands. Uses a TDMA-based air interface.
D-AMPS is the digital wireless standard used throughout the Americas, Asia and other continents. D-AMPS uses digital TDMA and is required to be compatible with installed AMPS base station networks on the other. D-AMPS operates on the 800 and 1900 MHz bands.
