Cellular telecommunication sector - Software Defined Radio
As of now, every cell phone transmits and receives information through a speci?c standard. If we have to change the service provider then we need to change the cell phone also. A Software De?ned Radio (SDR) reprograms the cell phones to operate on different radio standards by simply uploading different software running on a common hardware platform. It can switch from one radio standard to another radio standard. For ex- the software can be upgraded easily for switch over from 2G to 3G or 4G, CDMA to GSM.
