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.

third-generation (3G) wireless
standard defined in ITU
A
specification, is sometimes
marketed as 3GSM. The UMTS
uses GSM infrastructures and W-
CDMA (Wideband Code Division
Multiple Access) as the air
interface.
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

HSDPA (High-Speed Downlink
Packet Access) is a mobile
telephony protocol, used for
UMTS-based 3G networks and
allows for higher data transfer
speeds.
