多址接入 ：不同的用户使用不同的扩频码，可以在同一频率上同时进行通信，实现了多个用户在同一频段上的同时接入。
CDMA engineering permits multiple consumers to share the identical frequency band simultaneously by assigning a novel code (or channelization code) to each person. This code distinguishes a person consumer's data from another's on a similar frequency.
Though discussions did happen amongst ETSI as well as ANSI-forty one community with a see to consolidating collaboration initiatives for all ITU "family members," ultimately it was deemed appropriate that a parallel Partnership Undertaking be proven - "3GPP2," which, like its sister task 3GPP, embodies the many benefits of a collaborative effort (well timed shipping of output, speedy Operating techniques), even though simultaneously benefiting from recognition like a specifications-creating physique, providing easier access of the outputs into the ITU right after transposition from the requirements in the Standards Advancement Firm (SDO) right into a standard and submittal through the national more info course of action, as applicable, into the ITU.
