FDMA allows multiple users to share the same frequency channel by assigning a
frequency band within the existing channel to each user.
SCDMA allows multiple users to share the same frequency channel by assigning
a unique orthogonal code to each user.
3.1.12 The Multimedia over Coax Alliance
The Multimedia over Coax Alliance (MoCA) is a non-profit technology alliance, which
defines a set of specifications for the delivery of high-speed data, such as HD video,
over your building’s existing co-axial cabling network. Co-axial, or coax (pronounced
“ko-axe”) cable is already incorporated into most buildings for the transmission of RF
signals, traditionally for relaying television broadcasts from a TV antenna, satellite or
cable box to individual televisions around the building.
MoCA devices allow you use the coax cable network as an extension of your
building’s existing IP network, which includes both wired (Ethernet) and wireless
(WiFi) traffic. Because they bridge the two networks, they are known as Ethernet-to-
Coax Bridges, or ECBs.
