On 23 May, the Independent Communications Authority of South Africa (ICASA) published an amendment to Annexure B of the 2015 Radio Frequency Spectrum Regulations in Government Gazette No. 48643, effectively opening the use of the lower 6 GHz band for Wi-Fi services.The fact that Wi-Fi services now have access to the lower 6 GHz band will increase the availability and adoption of Wi-Fi services, enabling faster data transmission, lower latency, and increased data throughput.ICASA’s decision has been necessitated by the need to make substantial amounts of spectrum accessible for these technologies, distribute spectrum effectively, foster innovation, and ensure that regulations are developed in line with existing and emerging technologies aimed at revolutionising South Africa’s electronic communications sector.As the 6 GHz band is quickly emerging as a key enabler for broadband connectivity globally through license-exempt use, making the lower 6 GHz available for Wi-Fi/RLAN deployment supports South Africa’s national broadband plan (SA Connect), as well as its goals of facilitating socio-economic growth and development.Equally, there is significant interest in the upper 6 GHz band (from 6,425-7,125 MHz) by the mobile, satellite, and Wi-Fi/license-exempt industries. The upper 6 GHz band is being considered at the next International Telecommunications Union’s World Radiocommunications Conference (WRC) in 2023 for International Mobile Telecommunications (IMT) and the commercial use of mobile broadband applications using mobile technologies. This is already causing much debate between the two industries.Identifying the upper 6 GHz band for IMT in South Africa presents the following risks:
- Potentially harmful interference to existing services in the band (e.g., Fixed Services, Fixed Satellite Services, Radio Astronomy, and Earth Exploration Satellite Services).
- Weaken the full development and availability of the licence-exempt device ecosystem.
- Failure to generate the intended impact due to current and persistent electricity loadshedding, resulting in infrastructure failure and service/connectivity disruptions.
