Roland Piquepaille writes "According to Mitre computer scientist Joseph Mitola, next-generation cell phones might be cognitive radios (CRs), or software radios learning from interaction with their users and acting in their best interest. InfoWorld talked with him about how his vision of "cognitive radio" would work, and how it could redefine cell phone technology. Mitola said his vision is still about five to 10 years from realization, but that it could mean a sea change as control is shifted from network operators to users. He also said that sending a 10 MB email in a zone where carrier charges are high might cause the CR to alert its user, and suggest waiting until getting to the office to use the LAN instead. Finally, he talked about serious issues like privacy and security. For example, he envisions that video recognition would allow CR cell phones to visually authenticate their owners.
