<P>12Forever Surrey Spectrum crunch With the fourth generation (4G) of mobile phones rolled out in the UK in the last few months, already providing higher data speeds than 3G, why is research into 5G necessary? The answer is the sheer numbers of people who need or desire data on the move. By 2020, data traffic will have risen 1,000-fold on 2010 with an estimated 50 billion internet-capable devices. Without innovative technologies, the limited radio spectrum wont be able to cope. Research led by the 5G Innovation Centre is looking at new ways to use the spectrum more efficiently, while at the same time improving the service for users. Professor Tafazolli said: Even though 4G is a state-of- the-art system, we are short of radio spectrum. We need yet more advanced technologies to carry the huge amount of traffic we will be seeing in six years time. If we dont act now there will be a closing down of web opportunities instead of an opening up of new ones. This closing down is not an option when the global telecommunications industry is valued at $2.1 trillion per annum and is already responsible for 6 of the worlds gross domestic product. The big challenge, according to Professor Tafazolli, is to maximize the use of the limited available radio spectrum and provide more sustainable technologies and solutions. Surreys approach Researchers at 5GIC will be focusing on developing the know-how not the equipment, which Surreys partners will take forward. The two key areas are spectrum and energy efficiency. Higher speeds will result from the work, but this is not a priority target. We are not going for higher speed just to differentiate 5G from 4G. It will be faster but ?nding the technologies to enable 50 billion devices to connect to the internet in a few years time is more important, said Professor Tafazolli. The starting point for the research has been the end user and what they need from the technology. The research team has coined the phrase ‘perception of in?nite capacity as the byword for the user experience and has built user pro?les. Professor Tafazolli explained: This is our unique approach. Its all about making sure that at any given time the user will have a service that allows them to do all they want. Its ensuring they get value for money. Every time they want to connect to a website, for example, there should be no doubt over access. In coming up with new technologies and systems of network design, researchers are using mathematical and Artists impression of the new 5GIC building</p> <UL><LI><a href="http://www.mzines.net/publication/445/hwrgghleg/1/1/">Front-Cover</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/2/2/">Inside-Front-Cover</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/3/3/">Page-3</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/4/4/">Page-4</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/5/5/">Page-5</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/6/6/">Page-6</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/7/7/">Page-7</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/8/8/">Page-8</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/9/9/">Page-9</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/10/10/">Page-10</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/11/11/">Page-11</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/12/12/">Page-12</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/13/13/">Page-13</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/14/14/">Page-14</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/15/15/">Page-15</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/16/16/">Page-16</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/17/17/">Page-17</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/18/18/">Page-18</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/19/19/">Page-19</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/20/20/">Page-20</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/21/21/">Page-21</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/22/22/">Page-22</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/23/23/">Page-23</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/24/24/">Page-24</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/25/25/">Page-25</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/26/26/">Page-26</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/27/27/">Page-27</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/28/28/">Page-28</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/29/29/">Page-29</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/30/30/">Page-30</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/31/31/">Page-31</a></LI> <LI><a href="http://www.mzines.net/publication/445/hwrgghleg/32/32/">Back-Cover</a></LI> <LI><a href="http://www.mzines.net/publications/445/x/sitemap.xml" target="_blank">site map</a></LI> </UL>
