45、s 4.1.1 Radio frequency usage For many decades the UHF spectrum between 470 MHz and 862 MHz was used for terrestrial and cable broadcast TV distribution. It was decided to use 8 MHz channels in the UHF spectrum. The relevant portion of the channel raster is displayed in Figure 1. The same frequency
46、spectrum is used by terrestrial broadcasting over the air as well as by RF cable systems in a wired network. Co-existence is enabled by establishing a set of standards defining appropriate requirements for the separation of the wired transmission from its electromagnetic environment. With the more e
47、fficient usage of the spectrum by digital television, the terrestrial service portfolio can be maintained by using fewer frequency resources. The parts of the spectrum becoming available for alternative use are known as the Digital Dividend. Resulting from the decisions of the ITU World Radiocommuni
48、cation Conference (WRC) 2007 with regard to the future usage of the Digital Dividend many European countries are in the course of or have completed the reorganization of the relevant spectrum. Decisions by CEPT e.g. on the allotted bandplan in the 800 MHz band were taken with the aim to minimize imp
49、act on the Customer Premises Equipment (CPE). The idea was that a base transmitter station was expected to not have an impact to the disturbance situation to the same extent as UE. For example, the German government decided to make available the frequency range from 790 MHz to 862 MHz for mobile broadband Internet in Germany while the usage for terrestrial broadcasting services ceases. The main difference resulting for the electromagnetic environment compared to the previous usage by broadcast services is the presence of radio signa
