In the future Ill have a cell phone that will be capable of doing all following.
- Receive AM, FM and all other sorts of radio
- Connect to GSM, CDMA, and any other network technology
- Receive and decode satellite video
- Receive and decode terrestrial TV transmission
- Be my wifi and wimax transceiver
This is all that I can think of now. The point is that your cellphone will become a universal communication device that can handle any communication technology. If some new technology developed, all you need is to upgrade the software, just like we upgrade linux or windows. This is what software defined radio has in store for us.
In SDR the emphasis is on creating a universal hardware for receiving signals, and then do all the processing on a software platform which So if tomorrow a new communication protocol is invented, all you need to do is, upgrade your software.
More than the end user, the immediate benefits of SDR is to a service provider, like your cell phone service provider. He incurrs a huge cost in upgrading all his equipments when a better technology is released. But with this system, he can use a universal transmission system which can be upgraded to handle any technology just by upgrading the software. This will save the serivce provider a lot of money, and also will result in better customer experience.
