CDMA2000 1X (IS-2000), also known as 1x and 1xRTT, is the core CDMA2000 wireless air interface standard.The designation "1x", meaning 1 times radio transmission technology, indicates the same radio frequency (RF) bandwidth as IS-95: a duplex pair of 1.25 MHz radio channels. 1xRTT almost doubles the capacity of IS-95 by adding 64 more traffic channels to the forward link, orthogonal to (in ...
Cellular network standards and generation timeline. This is a comparison of standards of wireless networking technologies for devices such as mobile phones.A new generation of cellular standards has appeared approximately every tenth year since 1G systems were introduced in 1979 and the early to mid-1980s.
also known as CDMA2000, the successor to 2G CDMA ; IMT-2000 CDMA TDD. also known as TD-SCDMA; IMT-2000 TDMA Single Carrier. also known as EDGE, an intermediate 2.5G technology; IMT-2000 FDMA/TDMA. also known as DECT; To meet the IMT-2000 standards, a system must provide peak data rates of at 384 kbit/s for mobile stations and 2 Mbit/s for fixed ...
the 3GPP/UMTS 3G radio interfaces WCDMA, HSDPA and HSUPA used globally. the 3GPP2 2G standard cdmaOne (IS-95) and 3G standards CDMA2000 1x and 1xEV-DO, used especially in the U.S. and South Korea; the Chinese TD-SCDMA system. The terminology used in this article is firstly based on 3GPP2 standards.

This technique is a form of mobile-assisted handover, for IS-95/CDMA2000 CDMA cell phones continuously make power measurements of a list of neighboring cell sites, and determine whether or not to request or end soft handover with the cell sectors on the list.
A CDMA2000 mobile phone. Synchronous CDM (code-division 'multiplexing', an early generation of CDMA) was implemented in the Global Positioning System (GPS). This predates and is distinct from its use in mobile phones. The Qualcomm standard IS-95, marketed as cdmaOne.
