Question about Cell Phones
Originally, the acronym GSM stood for Groupe Spécial Mobile, a group formed by the Conference of European Posts and Telegraphs (CEPT) in 1982 to research the merits of a European standard for mobile telecommunications. Commercial service using the GSM system did not actually start until 1991. Instead of using analog service, GSM was developed as a digital system using TDMA technology.
Definition: The most common and most recent digital cellular technology in North America. What differentiate CDMA from other phone technologies is that in order to carry many conversations over one frequency, it sends all communications in groups of bits mixed altogether, but tags each group, belonging to a specific communication, with a different code (CDMA stands for &Code Division Multiple Access&). Therefore, at the other end, each communication can be rebuilt in the correct order, based on the unique codes attached to certain groups of bits.
Alternate Spellings: CDMA stands for &Code Division Multiple Access&
Common Misspellings: Don't misplace it with TDMA, which is another digital cellular technology.
