Interim Standard 95 (IS-95), the first CDMA-
based digital cellular standard pioneered by
Qualcomm. The brand name for IS-95 is
cdmaOne. IS-95 is also known as TIA-EIA-95.

CDMA2000 is a hybrid 2.5G / 3G protocol of
mobile telecommunications standards that use
CDMA, a multiple access scheme for digital radio.
CDMA2000 1xRTT (1 times Radio Transmission
Technology) is the core CDMA2000 wireless air
interface standard. It is also known as 1x, 1xRTT,
or IS-2000 and considered to be a 2.5G or 2.75G
technology.
2.75G

Enhanced Data rates for GSM Evolution
(EDGE), Enhanced GPRS (EGPRS), etc.
3G Packet-

UMTS (Universal Mobile
Telecommunications System), a third-
generation (3G) wireless standard
defined in ITU specification, is
sometimes marketed as 3GSM. The
UMTS uses GSM infrastructures and W-
CDMA (Wideband Code Division
Multiple Access) as the air interface.
The International Telecommunication
Union (ITU) is an international
organization within which governments
and the private sector coordinate
global telecom networks and services.
CDMA2000 EV-DO (Evolution-Data Optimized,
originally 1x Evolution-Data Only), also referred
to as EV-DO, EVDO, or just EV, is an evolution of
CDMA2000 1xRTT and enables high-speed
wireless connectivity. It is also denoted as IS-856
or High Data Rate (HDR).
3.5G
Packet-
switched
HSDPA (High-Speed Downlink Packet
Access) is a mobile telephony protocol,
used for UMTS-based 3G networks and
allows for higher data transfer speeds.
4G/LTE Packet-
switched
The LTE (Long Term Evolution)
standard is based on the GSM and
UMTS network technologies.
