ITU-R FAQ on the Digital Dividend and the Digital Switchover (DSO)
INTERNATIONAL TELECOMMUNICATION UNION – RADIOCOMMUNICATION SECTOR ITU-R FAQ on the DIGITAL DIVIDEND and the DIGITAL SWITCHOVER A: DIGITAL DIVIDEND Question: What is the Digital Dividend? The digital dividend is the amount of spectrum made available by the transition of terrestrial television broadcasting from analogue to digital. Question: What makes the Digital Dividend possible? The Digital Dividend is made possible by the transition from analogue to digital TV broadcasting as a result of the improved spectrum efficiency provided by the new digital technologies: a) Digital video compression reduces the transmission size (bits) of the video signal. As a result, instead of one analogue TV programme several (typical four to twelve) digital programmes of equivalent quality can be broadcast in the same 6-, 7- or 8-MHz wide channel. b) Digital modulation (COFDM) minimizes the multipath interference effect (phenomena when the signal is received directly from the transmitter and as reflection from various objects). Consequently, the signal level required for good TV reception is significantly lower for digital, hence transmitter power is lower. Since the need to cope with multipath reception is reduced, this may also lead to a decrease in the number of broadcasting stations. c) The re-use distance is smaller, i.e. the same frequency or TV channel (for other programmes) can be used at locations that are closer to each other than in the analogue case. This reduction in the re-use distance is due to the fact that digital TV can operate at significantly lower protection ratios than analogue TV. d) The same frequency can be used by adjacent transmitters as long as the same broadcast content is transmitted, i.e. -

International Harmonisation and National Spectrum Management
Imperfect Harmony: International harmonisation and national spectrum management Imperfect Harmony: International harmonisation and national spectrum management Introduction Final preparations are underway for the World Radiocommunication Conference 2019 (WRC-19), a two-month conference beginning this October in Egypt. The world radiocommunication conference (WRC) is held every three to four years, with the overarching objective to review and revise the Radio Regulations. The Radio Regulations are international treaties between member states of the International Telecommunications Union (ITU)1 that govern the use of radio spectrum and satellite orbits. International governance of radio spectrum use aims to reduce cross-border interference and develop equipment ecosystems. This is done by regional (or global) allocation of frequencies for particular communications services2 and through implementation of technical and regulator standards. This process is referred to as spectrum harmonisation. Although spectrum harmonisation is an international effort, spectrum resources are (typically) managed and assigned at a national level. Harmonisation can therefore limit the decisions of national spectrum managers, and there may be instances where the collective international interest does not align with national interests. Though the role of spectrum harmonisation and role of cross-country coordination between national spectrum managers are well established, this essay discusses the benefits and limitations of harmonisation and considers emerging coordination issues that need to be addressed at national and international scale3. This essay argues that the harmonisation facilitates benefits of coordination – but fundamentally cannot deliver without national action. It also supports the view that national spectrum managers should, at times, prioritise national interests over international harmonisation. The essay concludes by summarising future issues beyond the scope of coordination that are relevant to cross-country coordination. -

Radio Spectrum Memorandums of Understanding and Agreements
Radio Spectrum Memorandums of Understanding and agreements Publication date: June 2017 About this document 1.1 This document provides details the Memoranda of Understanding (MoUs) and Agreements entered into by Ofcom relating to cross-border radio frequency coordination and the management of interference. The information provided in this document includes: Mobile Service and Broadband Wireless Business Radio Broadcasting Services: o BAND III (174-225/230 MHz) o BANDS IV/V (470-862 MHz) 1.2 MoUs define the signal power, in a specified frequency band, that may be received in a neighbour country from a station in the home country. Stations that exceed the defined power levels are coordinated directly between the administrations on behalf of the operators. MoUs do not give an absolute assurance of no interference into stations close to a border or set an absolute limit on the signal strength that may be received in one administration from a transmitter in another. They specify a trigger level, which is used to initiate a formal coordination procedure so that an administration may have knowledge of, and an opportunity to express concern about, transmitters in a neighbouring country. 1.3 Where they are available, recommendations published by the European Conference of Postal and Telecommunications (CEPT) typically provide a basis for the negotiation of MoUs with neighbouring administrations. It is unusual to make a separate assessment of interference between the UK and a neighbour administration. Ofcom contributes to the development of the CEPT recommendations. 1.4 The licensee is responsible for ensuring compliance with the terms of the MOU, Ofcom will coordinate with the neighbouring administration if the licensee is unable to comply.
