Software defined telephony

Cory Doctorow 9:27 pm Sun Jul 6, 2003

An NY-based company has announced that it will shipp software-defined-radio telephones that use code to determine what kind of network they communicate on: WiFi, CDMA, GSM, GPRS, or any other acronym of choice.

Sandbridge's chips create chameleon-like radios for cell phones capable of changing from one interoperable wireless standard to the next. The radios flip among Code Division Multiple Access (CDMA), Global Systems for Mobile Communications (GSM), and any of a clutch of other wireless standards using either software stored in the phone or downloaded over the air.
