| 4 | 3 | SDR presents a hard real-time computing challenge. The first generation of SDR mobile terminals will be very limited in computing resources (processing powers, interprocessor bandwidths, memory, power, etc.) and will, most probably, not be capable of supporting more than one RAT implementation at a time. The flexibility of these terminals is then a function of the capability of their reconfiguration managers, which need to track the states of the computing resources. On the contrary, the computing resources of SDR network elements are less limited. Nevertheless, an optimized (minimized) usage of computing resources could be highly desirable to reduce their operational costs, among others. |
