Compatibility of DVB-T services and IMT-2000 compliant mobile telecommunications in the UHF band of 470–862 MHz

Abstract

The spectral efficiency of the DVB-T protocol in comparison to the analog television systems will inevitably lead to the reduction of the UHF spectrum that is necessary for the current television broadcasts. Even if the number of available TV programs increases, or new services such as High Definition TV (HDTV) are introduced along with DVB-T, there will still be more available spectrum at any given area than today. The spectrum that will be released by most European countries when the full digital switchover is completed in 2012 has been designated as "digital dividend" and is a matter of controversy between broadcasters and mobile communications operators that wish to occupy part of it. This paper examines the coexistence of DVB-T and IMT-2000 mobile telecommunications in the UHF bands IV and V that are used today for television broadcasting on a primary basis. The situation in which both services operate in adjacent (or even in the same) channels is examined on both technical and regulatory grounds, so as to take into account the international standards and rules for television broadcasting and personal mobile communications, as expressed mainly by the International Telecommunications Union (ITU).

A survey of cognitive radio and TV white spaces in Malaysia

“…In the wireless communication service, spectrum sharing is known as the concurrent utilisation of a particular spectrum in a specific place depending on license, policy and regulations that differ because of the communication system and country . In the year 2015, the predicted frequency band for mobile communication will be 1300 MHz based on the International Telecommunication Union (ITU) report .…”

“…In the year 2015, the predicted frequency band for mobile communication will be 1300 MHz based on the International Telecommunication Union (ITU) report . Based on this trend, it means that spectrum sharing will become imperative in the very near future . The radio rules and policies are established based on essential foundations of worldwide radio regions.…”

Cross Border Interference between IMT-Advanced and DVB-T in the Digital Dividend Band

“…A detailed study was carried out [3] to identify frequency channel arrangements within this band for mobile services. The recommendations of the study were adopted in 2009 as the response of the European Union to the ITU request at WRC-07 to conduct sharing studies between mobile and broadcasting services [4] Based on the facts that a) the ITU has set aside the 470-862 MHz band for terrestrial digital broadcasting and b) future IMT-A mobile services will operate in the 791-862 MHz band [4], frequency sharing between the two systems (and consequently, performance degradation) are inevitable. The goal of this paper is to quantify the possibilities for compatibility between the two services and to propose a practical guideline for guaranteeing efficient spectrum usage and reliable service.…”

Coexistence analysis between IMT system and DTV system in the 700MHz band

“…These studies explain when and how deterministic analysis could be useful, given the simulation methodology and assumptions. In [3], [4], [5], [6], the coexistence between mobile and broadcasting systems is studied. In [3], the scenario of UMTS mobile systems interfering with DVB-T systems is considered.…”

“…In [4], an analysis of the performance degradation of a mobile system due to DVB-T interference is studied. In [5], the coexistence of DVB-T and IMT-2000 mobile communications in the UHF bands is studied and the technical outlines of the two systems are provided. In [6], an analysis of the coexistence of primary services is presented, focusing on the study of mutual interference between DVB-T broadcasting and 3GPP LTE systems.…”
