                Progress and Demand
        • Digital RF coming closer

        • Moore’s law still applies

        • Coding Schemes’ Processing requirements
          increase with each new air interface

        • ‘staged Software Radios’

                Staged Approach
        • SDR F defines different tiers for different use
                 Tier         Type          Reconfigurability level

                 0      HW     Hardware     Reconfiguration through exchange of hardware
                               Radio        components only

                               Controlled   software, limited to pre-defined set of
