Abstract :This paper presents multi-band and multi-location spectrum measurements campaign conducted in Nigeria in 80-2200 MHz frequency range. The objectives of the study are to quantitatively determine the actual radio spectrum usage profile situation in Nigeria and to determine the radio spectrum usage profile in Nigeria in time, frequency and space. The results from the spectrum measurements campaign shows that a lot of allocated frequency bands in Nigeria have very low signal occupancy rates with the occupancy rates vary randomly in time, frequency and space like other parts of the world. The spectrum measurements campaign results also show that the actual spectral occupancy in Nigeria is less than 10.00%. The low spectral occupancy rate in the five major metropolises suggests a hopeful future for dynamic spectrum access in Nigeria.
