4G Technology - An Overview
Expert for providing this content for RF Cafe. A lot of people are
asking the question, "What is 4G, and how is it different from existing
technologies?" This short article begins to answer the question. 4G
is still in its infancy, and is therefore somewhat evolving. The current
recession (as of 2009) is slowing progress, but advances are being made.
standards are constantly changing as technology advances and the publics
hunger for more content delivered to their portable devices faster is
a driving force behind these developments. At the moment you may be
aware that a majority of modern mobile phones and mobile broadband services
for PC and Laptop owners connect to 3G networks. This name refers to
the fact that this is considered to be the 3rd generation of mobile
telecommunications networking technology, and at the moment 3G networks
are capable of download speeds of between 3.6 Mbps and 7.2 Mbps. This
speed will depend on the network provider you choose, the level of 3G
coverage and the capabilities of the mobile platform you are using to
receive the signal. However, there are many companies who are working
on creating 4G technologies, or the 4th generation of mobile networking,
though at the time of writing 4G is not a standardized, unified technology
and there are different companies working on 4G products that won't
perform in the same way or to the same level.
At the moment 4G technologies are looking to be
similar in many ways to the wireless networks that you may have used
in your place of work or in your own home, only on a much larger scale
and integrated into mobile devices as well as desktop solutions. For
mobile users it will provide an `always on` mobile broadband connection
so that voice calls, media streaming and internet access will be constantly
at hand. Additionally the download speeds capable over 4G networking
should be far greater than is currently available on 3G or indeed any
home broadband service provided by a landline, with test 4G networks
in China delivering 100 Mbps download speeds. What`s even better news
is that this 100 Mbps speed is claimed by some companies to be the download
speed available when the subject is on the move in a train or a car.
If you're standing in one spot relative to the broadcasting beacon then
up to 1 Gbps data transfer speed could be possible. This is literally
an incredible development and a huge leap in terms of download speed
and will no doubt further revolutionize the way in which we have access
to the internet, as well as drastically lowering the cost of voice calls
which use relatively little bandwidth.
4G Future Options
At the moment most people have mobile phones and many will also
wireless broadband, either in their own homes thanks to a wireless
router or through a mobile broadband solution using 3G networks. Samsung
and other large manufacturers have been demonstrating 4G technology,
both WiBro (wireless broadband) and WiMAX for some years now, and there
are already mobile phones available that use this technology like the
HTC MAX 4G and the Nokia N810 WiMAX edition. Sadly 4G will not be available
on a large scale for a few years as standardizations are made and more
companies combine their efforts to define 4G, but when the time comes
it will be an incredibly exciting product.
