cellular ringtone Digital mapmaker Tele Atlas, manufacturer Socket Communications, and service provider gate 5 put forth their joint smart2go product, a GPS-driven bundle to navigation-enable personal digital assistants (PDAs) and smartphones. Consumers can buy the retail product and pay their wireless carrier for the air-time to download data, without having to wait for their carrier to implement an LBS offering of their own. The device incorporates a u-blox GPS chipset. Rob Roveta, senior director of product management for Qualcomm CDMA Technologies (QCT), the company's chipset division, stands by the 100 million figure, adding that the company actually counts conservatively, to ensure that it can meet investor requests for certification. He points out that these are not GPS receivers per se, but chipsets integrating GPS functionality along with other features such as modem, multimedia, and ringtone capabilities. QCT is embedding GPS across its product line, for all air interfaces, GSM now as well as CDMA. Its chipsets have location-enabled 150 phone models from 20 manufacturers.
