This section of the website will highlight new technologies and their impacts on regulations. The usage of the spectrum can be optimised by technological means, taking into account natural phenomenon of its capabilities and its constraints. The spectrum is used and not consumed and it is wasted if not used or not optimally and efficiently used. Optimal and efficient use of the spectrum is achieved by, among others, extensive frequency sharing with antenna directivity, geographical spacing, time sharing, etc. Use of spectrum can also be optimised by employing better technologies, including spectrum efficient modulation techniques. One of the main function of the Spectrum Management Authority (SMA) is to ensure that the spectrum be used efficiently, economically, rationally and optimally.
