Wireless networks are now advancing to third generation (3G) capabilities, providing increased data transfer rates that
make it easier to access applications and the Internet from mobile devices. Individual wireless access networks show limitations
that can be overcome through the integration of different technologies into a unified platform (i.e. 4G system) . Based on the
study, 4G mobile technology is in a determining and standardization stage. Although 4G wireless technology offers higher data
rates and the ability to roam across multiple heterogeneous wireless networks. Since 4G is still in the cloud of the sensible
standards creation, ITU and IEEE form several task forces to work on the possible completion for the 4G mobile standards as
well. 3GPP LTE is an evolution standard from UMTS, and WiMAX is another candidate from IEEE. These technologies have
different characteristics and try to meet 4G characteristics to become a leading technology in the future market. A 4G system is
expected to provide a comprehensive and secure all-IP based solution where facilities such as ultra broadband (giga-bit speed)
Internet access, IP telephony, gaming services, and streamed multimedia may be provided to users.
