Spectrum Occupancy of Cellular Networks in Pakistan for Cognitive Radio — Measurements using Spectrum Analyzer

Sajjad Ali, Zhe Chen, and Fuliang Yin
Abstract— The spectrum scarcity is one of the major problems of wireless communication systems, and studies have shown that the static allocated licensed bands are under-utilized. Recently, the Cognitive Radio has emerged as a promising solution to diminish the spectrum scarcity, in which, an unlicensed user can utilize the licensed spectrum until its transmission does not interfere with the transmission of the licensed user. In this paper, the spectrum occupancy of all the GSM service providers of Pakistan is measured using the spectrum analyzer. The measurements of spectrum analyzer are in power spectral density versus frequency plots. Measurements result show that the GSM 900 band is clearly under-utilized, so a Cognitive Radio Network can be a potential solution to be employed in the cellular networks of Pakistan to diminish the spectrum scarcity and to optimize the spectrum utilization.

Index Terms— Cognitive radio, spectrum occupancy, spectrum analyzer, cellular networks.
