What is 1xRTT?
Single-carrier radio transmission technology is a faster, 2.5G version of CDMA. Speedy 3G technologies, some of which also are based on CDMA, are supplanting 1xRTT in the marketplace. EVDO Q: What is EVDO? A: EVDO (Evolution Data Optimized) is a wireless broadband networking service that enables high-speed Internet access on your cell phone without the need for an access point. Q: What are EVDO Release 0 and Revision A? A: EVDO Release 0 supports forward data link speeds up to 2.4Mbps and reverse link data rates up to 153Kbps. EVDO Rev. A is a newer technology with maximum forward link speeds of 3.1Mbps and 1.8Mbps on the reverse. Q: What benefits does EVDO Rev. A offer? A: As the newer standard, EVDO Rev. A adds the ability to transmit VoIP (Voice over Internet Protocol) and video telephone conversations on the same carrier with simultaneous delivery of voice and data. Q: What carriers offer EVDO?

1xRTT, often abbreviated as 1x, is a designation referring to an operating mode of CDMA2000, a wireless technology used in CDMA cellular networks. The 1x in 1xRTT stands for one times the number of 1.25MHz channels, while RTT stands for radio transmission technology. CDMA2000 1xRTT is also called 3G1X, IMT-CDMA Multi-Carrier, or IS-2000. CDMA stands for code division multiple access. It is a mobile digital radio technology that transmits streams of bits. Unlike older cellular technology, all radios on the network can be active at the same time. CDMA was developed by a commercial company, Qualcomm. CDMA is the root technology of CDMA 1xRTT. CDMA2000 is a family of wireless standards that use CDMA technology to transmit voice, data, and signal information between cellular phones and cell sites. 1xRTT is the version of CDMA2000 that uses a pair of 1.25MHz radio channels. 1xRTT supports peak data speeds of up to 144 kilobits per second (Kbps). Since it offers high speed data services in ad
