According to the Nigerian Communications Commission, a trial of the fifth-generation mobile network has shown that there is no health risk connected with its use.
The trial was undertaken in six cities: Abuja, Lagos, Ibadan, Abeokuta, Kano, and Calabar, according to the commission’s draft consultation document on the deployment of fifth-generation mobile technology in Nigeria, which was published on Monday.
The tests, according to the regulatory agency, were carried out in compliance with the standards for general public exposure to changing electromagnetic fields issued by the International Commission on Non-Ionizing Radiation Protection in 1998, which were in effect at the time of the experiments.
The greatest radiation at 26 GHz millimetre wave at 5m away from the source was 4.3 per cent, and at 30m away from the source was 0.14 per cent, according to the findings.
While the greatest radiation at 3.5 GHz was 11.4 per cent at 5 meters away from the source, and 1.9 per cent at 30 meters away from the source, according to the ICNIRP specification of 61 v/m for frequency ranges 2-300 GHz.
“These results are far below the ICNIRP specification for protection of members of the public in the Guidelines and therefore suggest that no public health hazards are expected from the use of 5G in Nigeria,” the NCC said.
The telecoms authority stated that the new network would be deployed in two phases in the country. Phase one, which comprises non-standalone deployment, will begin in 2021, according to the company. Phase two, based on the stand-alone method, which relies on additional spectrum allocations, will begin in 2022, according to the NCC.
“The current race to deploy 5G networks is targeted at providing citizens with the benefits of the technology while at the same time enabling the activation of the digital economy,” it said.
The regulatory body said ‘5G network deployment will rely on the availability of sufficient radio spectrum at the low, medium and high-frequency bands to provide for the different use cases and applications.
“While some of these frequencies will be newly assigned for 5G network deployment, others will have to be re-farmed from other existing communication services,” it added.
Globally recognized spectrum bands for 5G deployment, according to the commission, are 24.25-27.5 GHz, 37-43.5 GHz, 45.5-47 GHz, 47.2-48.2 GHz, and 66-71 GHz.
The bands were claimed to be available and not assigned to operators at the time, except for the 26 GHz band, where an operator had been assigned two slots of two X 28 MHz each under the previous plan.
The operator’s license would be revoked, and the band would be licensed under the new TDD scheme, according to the industry regulator.
