4G Technology

4G

4G is the fourth  generation of mobile phone mobile communication  technology standards. It is a successor to the third generation  (3G) standards. A 4G system provides multi ultra broadband  Internet access.4G(Fourth Generation / Long Term Evolution) is the next stage in mobile network development and will provide users with much faster data speeds than 3G is able to.

With the exception of EE, existing mobile networks use 3G/UMTS technology, which is now 10 years old and struggling to cope with the needs of today’s data hungry users.

“The addition of 4G World makes it even more important for any business, regardless of sector, to attend Super Mobility Week and to learn from and network with the best wireless companies and executives. For companies looking to migrate their networks to 4G, CTIA 2014 will be the place to see all of the technologies, services and devices available,” said CTIA Vice President and Show Director Robert Mesirow. “As more international companies begin to deploy 4G networks, they look to the U.S. to learn from our experts and influencers throughout the mobile ecosystem.”

The 4G phones currently available in the UK are basically just LTE-equipped versions of current top-end 3G phones, such as the iPhone 5,Samsung Galaxy S4, and HTC, along with a few mid range handsets such as the Nokia Lumia 820

However, the iPhone 5 won’t run on O2 or Vodafone’s networks

One of the advantages to being late to the 4G party is that we’re spared the rubbish “first try” handsets that we suffered back when 3G came out, so don’t be shy to try the new 4G phones.

4G handsets are available on every network, though if, as in Three’s case, the network hasn’t launched its 4G service yet, you’ll be limited to 3G speeds for the time being.

Download Speed Of 4G

Well, so far we can only comment on Everything Everywhere’s network speeds, as this is the only 4G network with confirmed speeds at the time of writing, but it’s certainly impressive.

EE claims average download speeds of 12-15Mbps and typical maximum speeds of 40Mbps, with upload speeds averaging around 5-6Mbps with a typical maximum of 15Mbps.

Whether the other networks will achieve any higher remains to be seen, but 4G download speeds could theoretically exceed 100Mbps with upload rates of more than 50Mbps, though it’s unlikely we’ll see anything like that in the near future.

Why 4G Is So Fast?

4G’s impressive speed increase is achieved with the use of OFDM (Orthogonal Frequency Divison Multiplexing), a transmission technology used by the likes of ADSL, Wi-Fi, DVB-T, DVB-H and DAB.

Simply put, this enables 4G/LTE phones and tablets to stream video and play online games like never before, largely because 4G has been designed primarily as a data network, rather than a voice one and it uses the same TCP/IP protocols that underpin the internet.

4G is  the first and only conference and expo covering the entire ecosystem of next-generation 4G technologies that enable the mobile Internet revolution, including mobile network infrastructure, advanced devices, applications and content. Owned and operated by UBM Tech, this show provides insight into the state of the industry today and explores forward-looking advancements that will affect operators within the mobile ecosystem in the years ahead. As a ubiquitous network takes hold in the mature markets of North America, Europe and Asia-Pacific, operators are experiencing massive growth in broadband data usage and planning their network migration strategies and business models for monetizing mobile Internet enabled services. 4G World offers attendees an opportunity to research state-of-the-practice business models and advanced mobile technologies,
