Assessment of DVB-T Compatibility with LTE in Adjacent Channels in 700 MHz Band
The 2012 World Radiocommunication Conference allocated the 694 MHz 790 MHz (700 MHz) band to the International Telecommunication Union Region 1, which includes also Europe, for the mobile service on a co-primary basis with other services to which this band is allocated on a primary basis, and was identified to the International Mobile Telecommunications. However, countries of Region 1 will also be able to continue the use of these frequencies for their digital terrestrial television services, if necessary. This allocation will be effective immediately after the 2015 World Radiocommunication Conference. The objective of this paper is to assess the electromagnetic compatibility of Digital Video Broadcasting - Terrestrial operating below 694 MHz and mobile broadband (LTE) operating in 700 MHz band. The Minimum Coupling Loss method and Monte Carlo simulation within SEAMCAT software was used for interference analysis. An adjacent channel scenario between Digital Video Broadcasting - Terrestrial and LTE was performed to evaluate the impact of Digital Video Broadcasting - Terrestrial on LTE systems. The results obtained provide the minimum coupling distance required between Digital Video Broadcasting - Terrestrial and LTE in the 700 MHz band to maintain the necessary performance level of the LTE system.
