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 1Aug 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:WiMAX, the Worldwide Interoperability for Microwave
Access, is a telecommunications technology standardsaimed 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 inwireless 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 .
