3 G:

UMTS: Universal Mobile Telecommunications System is one

of the third-generation (3G) cell phone technologies, which is

also being developed into a 4G technology. Currently, the

most common form of UMTS uses W-CDMA as the

underlying air interface. Mobile Radio Telephone, USA,

3 G: HSPA:High-Speed Packet Access is a collection of mobile

telephony protocols that extend and improve the performance

of existing UMTS protocols. Three standards, HSDPA,

HSUPAand HSOPA, were established

HSUPA provides improved up-link performance of up to 5.76

Mbit/s theoretically. In Singapore, Starhub announced a 1.9

Mbit/s HSUPA Service as part of its new MaxMobile plan in 1

Aug 2007 [1]. In Finland, Elisa announced on 30.8.2007 1.4

Mbit/s HSUPA to most large cities with plans to add the

service to its whole 3G network within months

3 G:

HSDPA High Speed Downlink Packet Access provides

improved theoretical down-link performance of up to 14.4

Mbit/s. Existing deployments provide up to 7.2 Mbit/s in

down-link. Up-link performance is a maximum of 384 kbit/s.

3 G:

WiMAX, the Worldwide Interoperability for Microwave

Access, is a telecommunications technology standards

aimed at providing wireless data over long distances in a

variety of ways, from point-to-point links to full mobile

cellular type access. It is based on the IEEE 802.16 standard,

which is also called WirelessMAN.

4 G:

Traditional definition:

Fourth-Generation Communications System (also known as

Beyond 3G), is a term used to describe the next step in

wireless communications. A 4G system will be able to provide

a comprehensive IP solution where voice, data and streamed

multimedia can be given to users on an "Anytime,

Anywhere" basis, and at higher data rates than previous

generations. There is no formal definition for what 4G is;

however, there are certain objectives that are projected for

4G .
