Mobile and wireless networks have made tremendous growth in the last
fifteen years. Nowadays many mobile phones have also a WLAN adapter. One may
suppose that near soon many mobile phones will have WiMAX adapter too, besides
their 3G, 2G, WLAN, Bluetooth etc. adapters. Today 3G mobile systems are on the
ground providing IP connectivity for real-time and non-real-time services. On
the other side, there are many wireless technologies that have proven to be
important, with the most important ones being 802.11 Wireless Local Area
Networks (WLAN) and 802.16 Wireless Metropolitan Area Networks (WMAN), as well
as ad-hoc Wireless Personal Area Network (WPAN) and wireless networks for
digital TV and radio broadcast. Then, the concepts of 4G is already much
discussed and it is almost certain that 4G will include several standards under
a common umbrella, similarly to 3G, but with IEEE 802.xx wireless mobile
networks included from the beginning. The main contribution of this paper is
definition of 5G (Fifth Generation) mobile network concept, which is seen as
user-centric concept instead of operator-centric as in 3G or service-centric
concept as seen for 4G. In the proposed concept the mobile user is on the top
of all. The 5G terminals will have software defined radios and modulation
scheme as well as new error-control schemes can be downloaded from the Internet
on the run. The development is seen towards the user terminals as a focus of
the5G mobile networks. The terminals will have access to different wireless
technologies at the same time and the terminal should be able to combine
different flows from different technologies. Each network will be responsible
for handling user-mobility, while the terminal will make the final choice among
different wireless/mobile access network providers for a given service. The
paper also proposes intelligent Internet phone concept where the mobile phone
can choose the best connections by selected constraints and dynamically change
them during a single end-to-end connection. The proposal in this paper is
fundamental shift in the mobile networking philosophy compared to existing 3G
and near-soon 4G mobile technologies, and this concept is called here - the 5G.
Mobile and wireless networks have made tremendous growth in the last
fifteen years. Nowadays many mobile phones have also a WLAN adapter. One may
suppose that near soon many mobile phones will have WiMAX adapter too, besides
their 3G, 2G, WLAN, Bluetooth etc. adapters. Using IP for both, 2.5G or 3G
Public Land Mobile Networks (PLMN) on one side and WLAN on the other, raised
research on their integration. Regarding the 4G, its focus is towards seamless
integration of cellular networks such as GSM and 3G. Multimode user terminals
are seen as must have for 4G, but different security mechanisms and different
QoS support in different wireless technologies remain a challenge. However,
integration among different wireless networks (e.g. PLMN and WLAN) is
functioning in practice even today. But, different wireless networks from a
single terminal are used exclusively, that is, there is no combining of
different wireless access technologies for a same session (e.g., FTP download).
The proposed Open Wireless Architecture (OWA) in is targeted to provide open baseband
processing modules with open interface
parameters to support different existing as well as future wireless
communication standards. The OWA is targeted to MAC/PHY layers of future (4G)
mobile terminals. The referenced work above provides a ground for definition of
a concept for beyond 4G mobile networks, referred in this paper as 5G mobile
networks. . In the proposed concept the mobile user is on the top of all. The
5G terminals will have software defined radios and modulation scheme as well as
new error-control schemes can be downloaded from the Internet on the run. The
development is seen towards the user terminals as a focus of the5G mobile
networks. The terminals will have access to different wireless technologies at
the same time and the terminal should be able to combine different flows from
different technologies. Each network will be responsible for handling
user-mobility, while the terminal will make the final choice among different
wireless/mobile access network providers for a given service. The paper also
proposes intelligent Internet phone concept where the mobile phone can choose
the best connections by selected constraints and dynamically change them during
a single end-to-end connection.
In
this paper we have proposed 5G mobile phone concept, which is the main
contribution of the paper. The 5G mobile phone is designed as an open platform
on different layers, from physical layer up to the application. Currently, the
ongoing work is on the modules that shall provide the best QoS and lowest cost
for a given service using one or more than one wireless technology at the same
time from the 5G mobile phone.
A
new revolution of 5G technology is about to begin because 5G technology going
to give tough completion to normal computer and laptops whose marketplace value
will be effected. There are lots of improvements from 1G, 2G, 3G, and 4G to 5G
in the world of telecommunications. The new coming 5G technology is available
in the market in affordable rates, high peak future and much reliability than
its preceding technologies.
