Frequency and Network Planning Aspects of DVB-T2
Report ITU-R BT.2254 (09/2012) Frequency and network planning aspects of DVB-T2 BT Series Broadcasting service (television) ii Rep. ITU-R BT.2254 Foreword The role of the Radiocommunication Sector is to ensure the rational, equitable, efficient and economical use of the radio-frequency spectrum by all radiocommunication services, including satellite services, and carry out studies without limit of frequency range on the basis of which Recommendations are adopted. The regulatory and policy functions of the Radiocommunication Sector are performed by World and Regional Radiocommunication Conferences and Radiocommunication Assemblies supported by Study Groups. Policy on Intellectual Property Right (IPR) ITU-R policy on IPR is described in the Common Patent Policy for ITU-T/ITU-R/ISO/IEC referenced in Annex 1 of Resolution ITU-R 1. Forms to be used for the submission of patent statements and licensing declarations by patent holders are available from http://www.itu.int/ITU-R/go/patents/en where the Guidelines for Implementation of the Common Patent Policy for ITU-T/ITU-R/ISO/IEC and the ITU-R patent information database can also be found.

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. -

Each path supports three primary modes of operation: a reduced current and gain state to support WCDMA with an external LNA and interstage SAW, an EGPRS mode in which the LNA is connected directly to a SAW, and a high linearity mode to support WCDMA operation when directly matched to a duplexor. The three different modes provide approximately the same input impedances such that, even though the input match is optimized for one mode, all three modes are usable. Multi-mode RF inputs are converted to a common baseband path which is shared between WCDMA and EGPRS. This common baseband path is optimized for die area and current consumption through the use of a Freescale reserves the right to change the detail specifications as may be required to permit improvements in the design of its products. -
