- DVB-T and LTE coexistence in 800 MHz band
In-lab measurements of LTE interference into DVB‑T system on several widely used set-top boxes were taken. The goal of this project was to evaluate protection ratios and overloading thresholds that define interference of LTE base station signals into DVB‑T set-top boxes. We have also evaluated the impact of using TV amplifiers and LTE filters at the set-top boxes. The results can be used to model the quality of DVB‑T signal in a certain area, determine the approach to combat interference from LTE and establish spectrum regulation rules. Measurements include TV channels 51 to 60, 5 MHz and 10 MHz bandwidth LTE signals and various modulation schemes.
