The high increase in the growth of wireless devices with the present static radio spectrum management has created an inadequacy in the available radio spectrum and presently the spectrum regulatory bodies are of the view that static spectrum management approach giving right of way to use licensed is still efficient. In this paper spectrum occupancy of GSM 900 MHz, GSM 1800 MHz and 3G are investigated. The measurement is done with Advantest U3741 spectrum analyzer with the frequency range of 9 kHz to 3 GHz using energy detection method and selecting a 10 dBm noise floor value as proposed by the International Telecommunication Union (ITU). The study reveals a duty cycle of 35.31%, 9.59% and 28.08 for GSM 900 MHz, 1800 MHz and 3G respectively. The results show that the spectrum is highly underutilized. Read full PDF
