In 2012 the Communications Regulatory Authority of Lithuania reallocated 790-862 MHz band used by terrestrial TV operators for mobile communications purposes following an International Telecommunication Union decision. The aim of this paper is to experimentally investigate electromagnetic compatibility of Digital Video Broadcasting-Terrestrial receivers operating below 790 MHz band with LTE base stations operating in 800 MHz band and derive an analytical model suitable for further electromagnetic compatibility analysis. An experimental testbed using LTE hardware and DVB-T receivers was used for evaluation of adjacent channel LTE downlink signal interference impact on digital TV system. Also, effect of using third party hardware such as band-pass filters and wideband preamplifiers on interference was analyzed. The results obtained provide protection ratio and overloading threshold for the digital TV receivers in different operating scenarios which serve as a reference guide for regulatory authority, mobile operators and terrestrial TV providers.

The paper presents results of pulsed radar signal interference impact on multipleinput and multiple-output (MIMO) Long Term Evolution (LTE) downlink data service analysis. Interference from radar operating in 800 MHz frequency band is studied analytically and experimentally taking into account MIMO capacity performance under external interference, including the influence of radar orientation with respect to LTE receiver antenna.

Analytical and experimental investigation results of potential radar interference into Voice over LTE (VoLTE) service of LTE wireless network operating at 800 MHz frequency band are presented. In-lab experimental measurements are compared with computer based simulations to find limits for allowable interference levels and conditions at which radar interference causes strongest impact on voice communication quality.
