FDMA (frequency division multiple access) is the 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.

There are five basic access or multiplexing methods: frequency division multiple access (FDMA), time division multiple access (TDMA), code division multiple access (CDMA), orthogonal frequency division multiple access (OFDMA), and spatial division multiple access (SDMA).

A routing diagram or route diagram in the field of management engineering is a type of diagram, that shows a route through an accessible physical space. Routing diagrams are used in plant layout study, and manufacturing plant design.

So FDM is (usually) a straight analog transmission, there is no need to convert that to digital. In digital communication analog carriers are being used to carry digital information signal.

FDMS is First Data Merchant Services. EMS is Elavon Merchant Services. Your client(s) should have a login for these accounts (and I assume the others you have listed will have the same facility) where they will be able to download the relevant invoices relating to the payments taken out of their bank.

FDMA separates users by frequency — each user occupies its own radio channel. TDMA separates users by time — each user occupies the entire radio channel, but at different time slots. The differences between FDMA and TDMA are shown in Figure 1 (right).

Any UML diagram will fit into one of two broad categories: structural or behavioral. Structural diagrams analyze and depict the structure of whatever system users want to study. Behavioral diagrams describe what the system does, what actors it features, and what components are needed to build it.

FDMA can be used with both analog and digital signal but it generally used with analog signal. FDMA requires high-performing filters in the radio hardware, in contrast to TDMA and CDMA. FDMA is not vulnerable to the timing problems that TDMA has.

A data-flow diagram is a way of representing a flow of data through a process or a system (usually an information system). The DFD also provides information about the outputs and inputs of each entity and the process itself. ... The data-flow diagram is part of the structured-analysis modeling tools.

UMTS-FDD uses W-CDMA for multiple access and frequency division for duplexing, meaning that the up-link and down-link transmit on different frequencies. UMTS is usually transmitted on frequencies assigned for 1G, 2G, or 3G mobile telephone service in the countries of operation.

FDMA allows multiple users to send data through a single communication channel, such as a coaxial cable or microwave beam, by dividing the bandwidth of the channel into separate non-overlapping frequency sub-channels and allocating each sub-channel to a separate user.

The Data Flow Diagram (DFD) is a structured analysis and design method. It is traditional visual representation of the information flows within a system. Data Flow Diagram(DFD) is widely used for software analysis and design. A neat and clear DFD can depict a good amount of the system requirements graphically.

High Speed Downlink Packet Access (HSDPA) is an enhanced 3G (third-generation) mobile communications protocol in the High-Speed Packet Access (HSPA) family. HSDPA is also known as 3.5G, 3G+, or Turbo 3G.
