Foreword
Mobile communications were largely introduced by GSM at the beginning of the 1990s. A telecommunication revolution was born with the success story of this new mobile technology. Today, one cannot imagine his life without a mobile phone. The number of users of GSM in the world now approaches to be five billions. Since this huge success and the convergence with the IP world, new standards were created to combine the packet-switched technologies to GSM in order to access the Internet from any mobile device. From GPRS to 3G and 3G+, we have seen the evolution of the mobile telecommunication with the ambition to offer the possibility to surf through the Internet from anywhere and at any time. Again, 3G+ is a huge success and people change their life by using new devices such as smart phones to be connected permanently. Regarding this success, new applications are introduced to offer new services. However, the like of 3G+ is clearly the limited bandwidth which is not able to cope with the new multimedia applications. The need of new technology is crucial and the world of telecommunications is going to introduce the LTE and LTEAdvanced standards which are able to offer high bandwidth for the new applications. The promised bitrates are approaching those offered by the fiber optic local loop. This book offers to its readers, a complete view of the LTE standard. It permits employees at telecommunication companies and undergraduate and graduate students to understand this complicated technology. The book covers all the aspects of the LTE starting from the physical layer and going through MAC layer and convergence with the IP technology. The principle of Femtocell, this new concept of wireless deployment, is explained also
