One Phone, Many Radios
What would happen if consumers could buy a mobile phone or wireless device and then choose any wireless operator they wanted regardless of technology? That is one of the potential applications for software-defined radio (SDR). The New York Times is running a profile of Vanu one of the companies dedicated to developing SDR technology. The technology is still in early stages and limited to military and municipal applications. But eventually with the help of Moore’s law it could change the way we think about wireless services.
