Migration to 4 G: Mobile IP based Solutions
[attachment=19008]
Introduction
Wireless broadband technologies promise to make all
kinds of information available anywhere, anytime, at a
low cost to a large portion of the population. More user
devices than ever are going wireless for mobility and
flexibility. WiMAX is a 4G technology that's fairly well
accepted and will offer broadband data, voice & video
services. WiMAX (IEEE 802.16) with Wi-Fi (IEEE
802.11) will allow operators to deliver high quality voice,
video &data services on a metropolitan scale. While Wi-
Fi is able to provide high speed, localized, wireless
Internet access, the emerging WiMAX standard is a wide
area technology, supplying wireless coverage over an area
of several kilometers.
2. History of 4G
4G is basically a wireless phone standard and have a
life of its own. The original analog and digital cellular
services were invented to cut the wire on landline phone
service and give regular telephone service you could take
with you. But the bandwidth they offer for adding data
services is pretty meager, in the low Kbps region. First of
all, this family is the wireless telephone family [1].
Then the wireless phone family started competing with
the wireless Internet family. Now that a wireless/cell
phone is not merely a cell phone, but also a PDA, a
messaging system, a camera, an Internet browser, an
email reader. This is the place where the whole "G" thing
got started [1]. That new generation of cell phone service
has been dubbed 3G for 3rd generation.
Viability of WiMAX as an Alternative to 3G and Migration towards 4G
Introduction of mobility into the WiMAX roadmap, as
well as the slow and expensive roll-out of 3G in many
areas of the world, has changed the picture, and WiMAX
is seen as a direct challenge to some 3G operators. This
section gives the answer to the Mobile carriers' burning
question, how WiMAX will pose a significant threat to
cellular voice and will compete with their cellular
networks and migrate towards 4G.
Characteristics of 4G / WiMAX Network
4G wireless networks can be realized with an IP-based
core network for global routing along with more
customized local-area radio access networks that support
features such as dynamic handoff and ad-hoc routing as
well as newer requirements such as self-organization,
QoS, multicasting, content caching, etc.. For a successful
deployment of the 4G technology, it is imperative that we
define the vision for the 4G services and applications that
effectively meet the users need. The vision that’s driving
us is the users’ vision as listed below:
(i) Broadband: You want to be able to send and receive
all kinds of information — images, video, big data files
and do it anywhere. 100 MHz per operator is required for
4G voice, video & data services.
8.1 WiMAX micro cells formed with Wi-Fi (migration path towards 4G)
At the moment Businesses should consider using both
Wi-Fi and WiMAX, because it will take a while for
WiMAX radios to get inside laptops. Wi-Fi is already in
laptops, cell phones and PDAs. One of the first uses of
WiMAX will be backhaul for Wi-Fi hotspots forming a
micro cell. With WiMAX hotspots will be converted into
so called “hot zones”, for users of Wi-Fi VoIP phones,
such as the VoiceLine XJ100 by Net2Phone and hence
leads the path 4G . WiMAX may be used to tie together
these municipal Wi-Fi “mesh networks” so that a VoIP
phone user traveling from, one place to another would
never lose coverage.
Conclusion
We all know that in 5 years, 4G should be a reality and
VoIP is going to drive new revenues and business models
in the decade to come. Certainly, analyses done in the
paper shows that WiMAX will win the marketplace and
will capitalize on this and will further support the
proliferation of VoIP devices and IP-based services. At
the moment combination of WiMAX with Wi-Fi has the
potential to compete on a cost-per-megabyte level with
cable and DSL. The main advantage of this combination
is that the whole geographic area becomes a hot zone and
leads the path towards 4G.
