On 28 March 2025, South Africa's Independent Communications Authority (ICASA) launched a public consultation on dynamic spectrum access and opportunistic spectrum management for the innovative spectrum frequency ranges 3800-4200 MHz and 5925-6425 MHz. The public consultation referred to 3800-4200 MHz as ISFR 1 and 5925-6425 MHz as ISFR 2. For each frequency band, the equipment deployment height, EIRP and power spectral density (PSD) limit requirements are given for different environments (indoor, urban outdoor, rural outdoor).
