Conclusion
New situation in spectrum occupancy and usage in UHF band• New situation in spectrum occupancy and usage in UHF band• New temporary broadband services like ECMA-392, LTE-Advanced, …• New services provided with a mechanism to reduce/avoid collisions with PMSE • No protection against audible interference for state-of-the-art PMSE devices
• PMSE become cognitive to increase operating robustnessg p g• New functionalities:
• LQI measurement• Remote control channel for control of mobile terminals during operationRemote control channel for control of mobile terminals during operation
• Panic reaction triggered by LQI decrease• Proactive reaction triggered by environment changes
• Additional scanning system to support proactive case• Increase of interference detection probability• Partitioning of operation area into several scanning clusters
