Ghana(2, 3)Anritsu MS2601A(2) and MS2721B(3)NI(2) or (3)NI(2), 1–2 min, 0–2 GHz; 800–1000 MHz and 1700–1900 MHz(3)Log –periodic(2), Anritsu log-periodic MP666A(3)1.5 m(2), 1.7 m(3)Six-minute weighted averaging time was used for all measurements. Measurements taken in direct line of sight to base station. The signals were measured during the day over a period of 3 h between 1000 and 1300 at a distance of ∼300 m from each base station(2)
Each measurement point consisted of three measured data based on the orientation of the antenna (horizontal, vertical and slanted) for duration of 1–2 min(3)
Ivory Coast(4)NINININININI
Mauritania(5)NININININIMeasurements performed mainly in the vicinity of the base station at distances ranging from 17 to 100 m on the three sectors
Nigeria(6)Agilent E4407B ESA-E series10 kHz and 30 kHzMax hold on during entire scan time
940–960.1 MHz and 1.82–1.865 GHz
HornNIMeasurement of the base station signals conducted from 9:00 am to 5:00 pm local time. During this time interval the maximum hold button on the spectrum analyzer was enabled
South AfricaNarda SRM 3000 or 30061 MHz
integration was performed using noise bandwidth=1.0552 RBW
30 s max hold
75 or 27 MHz to 3 GHz
Frequency step size: 500 kHz
3-axis isotropic E-field antenna1.5 mAt each site a number of positions were identified as positions of public interest and also positions of maximum potential exposure (where the main lobe hits the ground). A sweep of each identified area is performed to get the location of the local maximum. No positional sweeping was performed during the measurement itself
Zambia(7)NIUp to 20 MHz but no specific informationMax and min hold
80–2500 MHz; 920–960 MHz; 1.80–1.88 GHz and 2.11–2.17 GHz
Active antenna and PCD 8250 bi-conicalNI stationary measurements were made as well drive by testsThe stationary measurement consisted of fields from all angles in the x, y and z directions in a volume of 1 cubic metre of air at two distances (100 and 200 m) from the antenna. By using the instruments ‘max-hold’ function and by moving the antenna in the x, y and z directions for 6 min the maximum amplitude of the existing wavelengths was captured no matter of the polarisation
Each spectral plot consists of 301 samples, often 10 MHz apart to cover the whole range of 0–3 GHz. Every sample consists of a min and max value detected by very fast peak detectors. When the next sweep commences the old data is updated with even stronger or weaker samples. After 10 sweeps the buffer contains the max and minima of the whole 10 sweeps for the frequency range. Storage is done every 0.9 seconds at the fastest rate, as the system normally is configured the rate is ∼1.1 s
