    ii. Spectrum occupancy measurement at different places in Kolkata Measurement has been taken from 1 MHz to 2.5 GHz in four different regions of urban Kolkata. We divide the entire spectra of 2.5 GHz into several 200 MHz subintervals and record the spectrum usage for this frequency interval. The measurements were conducted using a spectrum analyzer and antennas. For low frequencies upto 1 GHz, a fully extended dipole antenna (39”) especially designed for TV signal reception is used and for frequencies above 1 GHz a helical antenna is used. We chose four suitable locations in Kolkata for our measurements, one in north Kolkata near Airport, one in central Kolkata at Rajabazar, one in Saltlake which is in the eastern part of the city and the last one is taken at Golf Green in south Kolkata. These different places at different corners of the city will give an indication of the variability of spectrum usage. In the measurement plots we mainly show the received signal level in dB averaged over 2000 samples at each frequency bin and measurements also captured the maximum value of the 2000 samples. The average value of the signal level eliminates burst signal and shows a peak for a steady deterministic signal. On the other hand maximum value is useful to capture burst signal.
