Coexistence of DVB-T2 and LTE in the 800 MHz band
Walach, Dominik ; Miloš, Jiří (referee) ; Polák, Ladislav (advisor)
This bachelor thesis deals with the study and evaluation of coexistence scenarios which can occur between DVB-T2 and LTE systems in the UHF band 800 MHz Both DVB-T2 and LTE systems are briefly described, and their common frequency bands are defined. An appropriate laboratory workplace is proposed and realized for the measurement, analysis and evaluation of the DVB-T2 and LTE coexistence scenarios. These systems work in adjacent or even in the same frequency bands. Thereby these systems can coexist, and different coexistence scenarios can occur.

Coexistence of wireless communication systems and LTE in the ISM band
Mikláš, Michal ; Kratochvíl, Tomáš (referee) ; Polák, Ladislav (advisor)
This bachelor thesis deals with a definition, description and measurement of coexistence scenarios which can occur between LTE and WLAN (technology IEEE 802.11xx) wireless communication systems in the ISM band. Based on the common radio frequency (RF) bands, used by these systems, different coexistence scenarios are defined. Appropriate measurement testbed and method are proposed to measure coexistence between LTE and WLAN systems. Functionality of the proposed measurement testbed has been proved and extensive measurement of previously defined coexistence scenarios has been done. The obtained results are evaluated in details.

Co-existence of the still used and upcoming digital terrestrial television and mobile communication services
Plaisner, Denis ; Kratochvíl, Tomáš (referee) ; Polák, Ladislav (advisor)
This work deals with exploring, measuring and evaluation of possible coexistence scenarios between terrestrial digital TV (DVB-T/HT2) and mobile wireless services (GSM, LTE), which can occur in a shared RF frequency bands The DVB-T, DVB-T2 and LTE standards are briefly described. RF band, where these systems are operated, are outlined too. . There are defined different coexistence scenarios. For the measuring, monitoring and evaluation of these scenarios, an appropriate laboratory workplace is proposed and realized. Results from the measurements show various influence of interfering mobile services on the interacted DVB-T/H system, depending on the considered coexistence scenario.

Coexistence Between DVB-T And LTE Services In a Shared Frequency Band And Their Measurement
Plaisner, D.
This work deals with exploring, measuring and evaluation of possible coexistence scenarios between Digital Video Broadcasting-Terrestrial (DVB-T) and Long-Term Evolution (LTE) mobile services, which can occur in a shared radio frequency (RF) bands. There are considered two different coexistence scenarios: partial overlapping and full overlapping RF spectrum. For the measuring, monitoring and evaluation of these scenarios, an appropriate laboratory workplace is proposed and realized. Experimental results show that the performance of DVB-T system is differently influenced by the interfering LTE services in considered coexistence scenario.
