Gadget Overload Relief in Sight

Software defined radio (SDR) is an idea that we're going to start hearing a lot more about. It's an enabling technology that could get us closer to one wireless device that can be used anywhere and support multiple wireless applications. SDR replaces radio hardware with software that can be reprogrammed on the fly. SDR could be used to allow roaming between different network technologies or update handets to take advantage of new applications. Carriers could roll out new services without requiring handset upgrades. Network related updates seem more promising that application updates. As we've seen with the initial roll-out of new data services, convergence applications require new devices for an optimal user experience. While SDR might make handsets more flexible it doesn't help solve the problem of multifunction devices which support many applications, but do few very well. Hardware will always be an issue.
