Spectrum Occupancy Measurements and Analysis in Beijing
چکیده انگلیسی

A 24-hour spectrum measurement campaign was performed in Beijing in 2012 August in the frequency bandwidth which is 450-2700 MHz in order to find out the radio spectrum allocation situation in Beijing, and identify frequency bandwidth which can be used by dynamic spectrum access devices. The results from the spectrum measurements indicate that a lot of spectrum in Beijing has very low signal occupancy in both time and spectrum domains. The measurement results show that the actual spectral occupancy in Beijing is about 13.5%. The low spectral occupancy rate even in a metropolis such as Beijing suggests a bright future for aggressive expansion of the cognitive radio and other dynamic spectrum access.
