Implementation of combined geolocation database and infrastructure sensing in TV bands using different spectrum devices

In the present day, the TV Band has become a realistic option and has attracted much attention due to the potential to exploit underutilized TV white space for other communications, based on time and location. In this paper, we design a flexible system which uses a combination of geolocation database and spectrum sensing in the TV band, comparing the performance of different spectrum analyzers (Agilent E4407B, Agilent EXA N9010A and a low cost RTL-SDR) in the real environment.
