Multiple Access Techniques : FDMA, TDMA & CDMA

 · These multiple access techniques are used in the various mobile communication systems. The 1G analog AMPS system used FDMA. The 2G digital systems D-AMPS/IS-136 & GSM use TDMA+FDMA. And the CDMA/IS-95 system uses CDMA. SEE ALSO Mathematical Modeling of Control Systems & Transfer Function Modeling.

Wikizero

IS-54 e IS-136 son sistemas de telefonía móvil de segunda generación (), conocidos como Digital AMPS (D-AMPS). Alguna vez fue predominante en América, particularmente en los Estados Unidos y Canadá.D-AMPS está considerado en etapa de desimplementación, y las redes existentes han sido reemplazadas en su mayoría por las tecnologías GSM/GPRS o CDMA.

Digital AMPS

 · IS-54 and IS-136 are second-generation (2G) mobile phone systems, known as Digital AMPS (D-AMPS), and a further development of the North American 1G mobile system Advanced Mobile Phone System (AMPS). Later, many AMPS networks were partially converted to D-AMPS, often referred to as TDMA (though TDMA is a generic term that applies to many 2G.

States. Both D-AMPS and AMPS are now used in many countries. D-AMPS adds Time Division Multiple Access (TDMA) to AMPS to get three users for each AMPS channel, tripling the number of calls that can be handled on a channel. D-AMPS is known as IS-136 from the Electronics Industries Assocation/Telecommunication Indus-tries Assocation (EIA/TIA).

IS-136 is an evolution of the IS-54 standard. Both are known as Digital AMPS (D-AMPS), a 2G technology used particularly in the United States and Canada. IS-136

IS-136 - often also referred to as TDMA - was originally an important mobile radiocommunications standard in the Americas, but it has meanwhile been replaced by GSM/GPRS and CDMA® technologies. D-AMPS transmits in the same 30 kHz frequency bands as analog AMPS, which results in a smooth transition from an analog to a digital system.

A Comparative Study of Three TDMA Digital Cellular Mobile

referred to as Digital-AMPS (D-AMPS), was the first of these. It shares the same 21 analogue call set-up channels with AMPS so that the call processing is the same between the two systems and handsets can support dual AMPS/ D-AMPS. The second phase standard is IS-136 which implements digital call set-up.

The Commercial and Technology Challenges for TDMA …

TDMA/IS-136 operators must deal in choosing a 3G alternative. Five sets of issues stand out. These are: 1. To increase average revenue per user (ARPU). 2. To minimize costs of technology deployment To adopt as simple (and, therefore, as painless) a deployment process as possible. 3. To deploy viable commercial services in a timely manner. 4.

Digital Advanced Mobile Phone System

 · D-AMPS uses a combination of time division multiple access (TDMA) and frequency division multiple access (FDMA). It adds TDMA to get three channels per AMPS channel, thus tripling the number of calls on a channel. Features. They are standardised by IS-54 and IS-136. As in AMPS, D-AMPS also uses frequencies from 800 to 900MHz for transmission.

D-AMPS (Digital AMPS), josta käytetään myös nimiä US-TDMA tai pelkästään TDMA, on toisen polven digitaalinen matkapuhelinjärjestelmä, jota käytettiin lähinnä Pohjois-Amerikassa, mutta jossain määrin myös Etelä-Amerikassa ja Israelissa.Järjestelmä tunnetaan myös Telecommunication Industry Associationin tekemien standardien nimillä IS-54 ja IS-136, joka jäi päätepisteeksi.
