Code Division Multiple Access
A spread spectrum approach for the digital transmission of data/voice over radio frequencies. Sound bits are digitized and the data is split into data packets that are encoded with unique identification tags. All of the data/voice is sent over a spread range of radio frequencies. The cell phone or data device receives all of the data packets but only re-assembles those packets with the correct code and transforms the broken-up bits of data into useful sound and data. This allows more traffic for a finite number of available frequencies than analog or the other digital standards.

Get the CDMA mug.FREQUENCY MODULATION
radio modulation techique where information (usally voice or music) is added to the signal and changed by varying the freqeuncy of the transmitter. FM is the most commonly used modulation for radio signals techneque above 30 MHz.
the term "FM" is also used to refer to the broadcast band from 88.1 to 107.9 MHz, using that same modulation mode.

FM signals have less static because changes in frequency do not pick up interferance that AM-modulated signals do.

crew slang:
park in northern virginia, run by the Northern Virginia Regional Park Authority. Its right on the occoquan sewage dump (a.k.a. occoquan reservoir)
place were all the good crew teams practice (or in the case of TJ crew, sit around and play on thier TI-83s). Also the site of the NCASRA crew races. Good place with lots of good memories.... also where fairfax crew owns all.
