Wireless communications is becoming a pervasive technology that we use throughout our lives. Across society, there is a move away from using the internet on desktop computers and towards mobile phones, laptops and tablets. This means that the amount of data transmission to support our online activity is rapidly increasing. There is also significant growth in automatic data sharing and collection from many types of sensors, meters and computers, sometimes called machine-to-machine communications. Mobile network operators face major challenges in setting up their networks to meet the increasing traffic load. They would like to provide a rich and seamless internet connection experience to their subscribers, but this must be traded off against the financial and energy costs of their network.There are three major concepts or trends that can assist mobile operators to improve their networks. The first is the concept of heterogeneous networks which includes both wide area large cells or macrocells and short range small cells that allows the network operator to target areas of high traffic demand such as offices or shopping malls. Using small cells provides a low cost and low energy solution to provide high data rate services to subscribers. The second concept is the use of more radio spectrum to meet traffic demand. The UK government has recently been auctioning more radio spectrum to network operators to boost capacity. However, by using a new set of higher frequency bands called the millimetre wave spectrum, much higher data rates may be achieved. The drawback is that radio signals do not propagate as far as for existing mobile broadband frequencies, so they are probably best suited to short range small cells.The third concept relates to efficient management of radio spectrum with a large number of small cells operating. The first danger in this scenario is that the complexity of managing the large number of cells and frequencies becomes impossibly complex. A second major problem relates to the potential for significant interference between small cells, which limits their efficiency. One solution to these problems are so-called "phantom cells". These use a separate higher power data link to coordinate the activities of all mobiles and thus limit the complexity of the system.This project will study new ideas to manage the growth of heterogeneous networks and and the use of new spectrum bands in an efficient way. These methods will manage the network resources in a simple manner and will tackle interference effectively. They will yield a network that provides a good quality of experience to subscribers in a more energy efficient way than today's mobile networks.

无线通信正在成为我们一生中使用的普遍技术。在整个社会中，可以从台式计算机上使用互联网转向手机，笔记本电脑和平板电脑。这意味着支持我们在线活动的数据传输量正在迅速增加。从多种类型的传感器，仪表和计算机中，自动数据共享和收集的自动数据共享也有显着增长，有时称为机器对机器通信。移动网络运营商在建立网络以满足不断增加的流量负载方面面临着主要的挑战。他们想向订户提供丰富而无缝的互联网连接体验，但这必须与网络的财务和能源成本相抵触。有三个主要概念或趋势可以帮助移动运营商改善其网络。首先是异质网络的概念，该网络既包括大区域大细胞或宏观细胞和短距离小单元，允许网络运营商针对高流量需求的较高需求区域，例如办公室或购物中心。使用小单元提供低成本和低能解决方案，为订户提供高数据速率服务。第二个概念是使用更多的无线电频谱来满足交通需求。英国政府最近正在为网络运营商拍卖更多的无线电范围，以提高产能。但是，通过使用一组称为毫米波谱的新型高频带，可以达到更高的数据速率。缺点是无线电信号对现有的移动宽带频率并没有传播，因此它们可能最适合短范围的小单元。第三个概念与无线电频谱的有效管理有关，其中大量的小单元运行。在这种情况下，第一个危险是管理大量细胞和频率的复杂性变得难以置信。第二个主要问题与小细胞之间重大干扰的潜力有关，这限制了其效率。解决这些问题的一种解决方案是所谓的“幻象细胞”。这些使用单独的高功率数据链路来协调所有手机的活动，从而限制了系统的复杂性。该项目将研究新的想法，以管理异质网络的增长以及以有效的方式使用新频谱频段。这些方法将以简单的方式管理网络资源，并有效地应对干扰。他们将产生一个网络，以比当今的移动网络更节能地为订户提供良好的体验。
