What is 1x – 3G Protocol
1x is third generation (3G) protocol, although some may consider it as 2.5 or 2.75G technology, meaning it provides some but not all of the benefits of 3G. In its full designation, CDMA2000 1xRTT, “CDMA” stands for “code division multiple access”, while “1xRTT” stands for “1 times Radio Transmission Technology. This technology was pioneered by a wireless telecommunications research and development company known as Qualcomm. Of the four types of CDMA2000, 1x is the simplest and most basic type. It was introduced commercially in 1995, and had since become one of the fastest-growing wireless technologies in the world. 1x was a key stepping stone in wireless networking because it served as the basis for 3G wireless systems. In CDMA, frequency channels are defined with pseudorandom number sequences, and multiple transmitters are permitted on the same channel simultaneously.
