Abstract:

Discrete carrier aggregation broadband systems were introduced in the 223~235 MHz band to improve spectrum utilization efficiency and to meet the broadband application demand of industrial users. The interference between broadband system and in-band narrow band wireless radio were analyzed considering both single station interference and aggregated effect. Also, the interference between broadband system and out-of-band TV broadcasting system were calculated. Finally, the feasibility of frequency usage was proposed based on the interference calculation results.

Key words: discrete carrier aggregation, spectrum, sharing study
