Abstract: The Effective utilization of the radiofrequency electromagnetic spectrum is paramount for wireless communication systems especially in telecommunication. This paper presents measurements and analysis of spectrum occupancy in the telecommunication frequency bands performed in Kampala, Uganda in March 2015. The telecommunication bands considered in this study are GSM900, GSM1800, UMTS2100 and LTE2600. Occupancy measurements have been carried out in an outdoor setting using the Aaronia Hyperlog 70600 antenna and the Spectran HF-6065 V4.The analysis shows that the licensed telecommunication spectrum bands are not fully utilized. Highest spectrum occupancy of 52.4% was observed in the GSM900 Downlink telecommunication band while the lowest occupancy of approximately 0% was observed in the LTE2600 band.
