In the framework of the Policy and Regulation Initiative for Digital Africa (PRIDA), and on behalf of the ITU, a study was conducted on spectrum harmonisation, sharing and refarming. This project is to promote the introduction of more wireless broadband services (LTE and 5G/NR) in Africa in the following bands; 700 MHz, 800 MHz, 1.4 GHz, 2.3 GHz, 2.6 GHz, 3.5 GHz, 26 GHz band and the upper frequency range 37-71 GHz.
The report addresses the necessary technical and regulatory conditions for sharing and coexistence of IMT services and other services in the aforementioned bands. The report also covers best practices for refarming incumbent services and the funding of these refarming efforts.
