CDMA

Definition – What does CDMA mean?

Code Division Multiple Access (CDMA) is a wireless transmission technology developed during World War II by the English allies in order to avoid having their transmissions jammed. After the end of the war, Qualcomm patented the technology and completed it commercially available as digital cellular technology. Now it is a popular communications method of technology used by many cell phone companies around the world.

Unlike the TDMA and GSM, CDMA can also communicate over the entire frequency range available. It doesn’t assign a specific frequency to each user on the communications network. Because Code Division Multiple Access does not limit each user’s frequency range, there is more bandwidth available. This enables more users to communicate on the same network at one time than if each user was chosen a specific frequency range. Because CDMA is a digital technology, analog signals must be changed to digital signals before being transmitted on the network. CDMA is used by both 2G and 3G wireless communications and usually operates in the frequency range of 800MHz to 1.9GHz.
