Texas Instruments has a cellular handset platform that allows b/g or a/b/g integration with GSM, GPRS, CDMA, and EDGE: The two-chip solution relies on TI's earlier cell chip work, with which this system can integrate and make use of some overlap in materials. TI expects to ship the chips mid-year. Several technological improvements allow reduced interference, lower battery usage, and a reduction in the number of overall chips in a complete Wi-Fi/cell-phone design.
