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) | NI | NI | NI | NI | NI | NI |
Mauritania(5) | NI | NI | NI | NI | NI | Measurements 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 series | 10 kHz and 30 kHz | Max hold on during entire scan time 940–960.1 MHz and 1.82–1.865 GHz | Horn | NI | Measurement 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 Africa | Narda SRM 3000 or 3006 | 1 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 antenna | 1.5 m | At 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) | NI | Up to 20 MHz but no specific information | Max 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-conical | NI stationary measurements were made as well drive by tests | The 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 |
