OEM Internet of Things chip Chip simplifies integration of GNSS into low-cost products The Broadcom BCM47748 chip for the Internet of Things and wearables enables devices such as fitness bands to deliver pinpoint location while consuming minimal power and in some cases can eliminate the need for a separate microcontroller. The BCM47748 removes a bulk of the signal processing from the device MCU by calculating position, velocity and time on-chip, delivering significant system power savings. The chip uses intelligent firmware to extend battery life while maintaining accuracy in speed, distance and position. By absorbing location computations on-chip, Broadcom not only reduces power consumption but can also dramatically lower costs for OEMs by replacing the device MCU and reducing board space. Firmware inside the BCM47748 automatically adapts to user activity and context, whether biking, walking or running, to provide precise location results to the user, enabling performance that is not sacrificed for power savings.
