Secured Reconfigurable Software Defined Radio Using OTA Software Download

Dynamic Reconfiguration of lower layers of the protocol stacks used in communication terminals is a key for the development of future multimode software radio. Together with the use of software downloading, future terminals will become a platform to support the deployment of yet unspecified services and applications. Today software radio is viewed more as a technology to enable the reconfiguration terminals at all stages of design, and production. This paper proposes the concepts of software radio reconfiguration by software downloading on 3G and possible future 4G standards. The work is to discuss the Software Defined Radio (SDR) main challenges including the over the air software downloads, installation, execution and automatic reconfiguration.
