Frequency Division Multiple Access Access system that is based on frequency multiplex

frequency division multiple access; used to separate multiple transmissions over a finite frequency allocation; refers to the method of allocating a discrete amount of frequency bandwidth to each user

Frequency division multiple access. A method of enabling several communications devices to use the same transmission channel by allocating a portion of the capacity of the channel on a pair-by-pair basis using frequency division multiplexing (FDM).

Frequency Division Multiple Access. A multiple access technique in which signals from multiple stations are transmitted simultaneously but each signal must be allocated a portion of total bandwidth. Also see multiple access. Compare with TDMA.

Frequency Division Multiple Access. A digital radio technology that divides the available spectrum into separate radio channels. FMDA is normally used in conjunction with Time Division Multiple Access (TDMA) or Code Division Multiple Access (CDMA).

FDMA (frequency division multiple access) is the division of the frequency band allocated for wireless cellular communication into 30 channels, each of which can carry a voice conversation or, with digital service, carry digital data. FDMA is a basic technology in the analog Advanced Mobile Phone Service (AMPS), the most widely-installed cellular phone system installed in North America. With FDMA, each channel can be assigned to only one user at a time. FDMA is also used in the Total Access Communication System (TACS).

Frequency Division Multiple Access. FDMA systems transmit one voice circuit per channel. Each conversation gets its own, unique, radio channel. The channels are relatively narrow, usually 30 KHz or less and are defined as either transmit or receive channels. A full duplex conversation requires a transmit & receive channel pair. For example, if a FDMA system had 200 channels, the system could handle 100 simultaneously full duplex conversations. (100 channels for transmitting and 100 channels for receiving) Example: FDMA channel.

Frequency Division Multiple Access. A multiple access scheme that divides an allocated spectrum (see Frequency allotment) into different radio channels.

Frequency Division Multiple Access - a transmission technique where the assigned frequency band for a network is divided into sub -bands which are allocated to a subscriber for the duration of their calls.

Frequency Division Multiple Access. A method allowing multiple carriers to share a single satellite transponder or range of frequencies. The transponder bandwidth is divided into sub-channels, each of which is allocated to a particular earth station (carrier). The earth stations transmit continuously and the transponder conveys several carriers simultaneously at different frequencies.

Frequency Division Multiple Access (FDMA)-communicating devices at different locations sharing a multi-point or broadcast channel by means of a technique that allocates different frequencies to different users.

Frequency Division Multiple Access. A technique for allowing many users to share a transmission bandwidth by assigning each of them a share of the bandwidth such that the sum of all such user bandwidths plus necessary guardbands equals the allowed bandwidth.

The division of the frequency band allocated for wireless communication into individual channels, each of which can carry a voice conversation or, with digital service, carry digital data. FDMA is a basic technology for analog AMPS, which divides the cellular spectrum into 832 channels each with 30 kHz bandwidth. With FDMA, each channel can be assigned to only one user at a time. D-AMPS (digital AMPS) also uses FDMA but adds TDMA to get three channels for each FDMA channel, tripling the number of calls that can be handled on a channel.

Stands for Frequency Division Multiple Access. The technology that transmits multiple signals simultaneously over a single transmission path such as a cable or wireless system. Each signal travels within its own frequency.

frequency division multiple access – allocates a single channel to one user at a time, if the transmission path deteriorates, the controller switches the system to another channel. Although technically simple to implement, FDMA is wasteful of bandwidth and cannot handle alternate forms of a data, only voice transmissions. This is the basic technology used in cellular phones and is also used in the total access communication systems (TACS).

(Frequency Division Multiple Access) The analog communications technique that uses a common channel for communication among multiple users allocating unique time slots to different users.

Frequency division multiple access. Division of the frequency band allocated for wireless cellular telephone communication into 30 channels, each of which can carry a voice conversation or, with digital service, carry digital data. FDMA is a basic technology used in the analogue AMPS the most widely-installed cellular phone system installed in North America. With FDMA, each channel can be assigned to only one user at a time. The D-AMPS also uses FDMA but adds TDMA to get three channels for each FDMA channel, tripling the number of calls that can be handled on a channel. It is also applicable in fixed networks.

Frequency Division Multiple Access. An access technology that allocates different carrier frequencies to different users.

An analog standard that lets multiple users access a group of radio frequency bands and eliminates interference of message traffic.

Frequency Division Multiple Access. A cellular technology that has been used in the first-generation analogue systems (i.e., NMT, AMPS, and TACS).

Frequency Division Multiple Access Access method to a transponder by multiple stations each using 1 unique frequency

Frequency Division Multiple Access. Near-synonym for FDD.

Frequency Division Multiple Access. Method of allowing multiple users to share the radio frequency spectrum by assigning each active user an individual frequency channel. In this practice, users are dynamically allocated to a group of frequencies so that the apparent availability is greater than the number of channels.

Frequency division multiple access. Refers to the use of multiple carriers within the same transponder where each uplink has been assigned frequency slot and bandwidth. This is usually employed in conjunction with Frequency Modulation.

Frequency Division Multiple Access. FDMA is a technique used to allow more than one earth station to share the bandwidth of a satellite transponder. Each earth station is assigned a specific carrier or set of carriers for transmission over a specific portion of the bandwidth.

A multiple access scheme by dividing an allocated spectrum into different radio channels.

Frequency Division Multiple Access; A method of sharing a transmission channel by dividing the total bandwidth of the circuit into several smaller channels. This is accomplished by allocating specific frequency ranges to each channel. All signals are carried simultaneously.

Frequency-division multiple-access (FDMA) is a mechanism for sharing a radio frequency band among multiple users by dividing it into a number of smaller bands.

Stands for Frequency Division Multiple Access. This multiple access technique allows many cell phone users to communicate with one base station by assigning each user a different frequency channel. An AMPS network, for example, has 832 channels spaced about 30 KHz apart. In digital networks, FDMA is used in conjunction with CDMA or TDMA.

Frequency Division Multiple Access. Refers to the use of multiple carriers within the same transponder where each uplink has been assigned a frequency slot and a bandwidth. FDMA is one access scheme for the inbound channel of VSAT networks, as opposed to TDMA (Time Division Multiple Access)

A multiple access technique used in analog cellular systems, in which each user is assigned to a different frequency.
