ZigBee system-on-chip solution has location estimation capability

22 March 2006 Telecoms, Datacoms, Wireless, IoT

Chipcon's CC2431 is a system-on-chip IEEE 802.15.4 low power wireless sensor networking solution targeting ZigBee solutions. The new SoC solution includes a licensed location detection hardware core from Motorola.

The solution is based on Chipcon's CC2430, and Motorola's IEEE 802.15.4 standards based radiolocation solution, all in one single silicon die.

The CC2431 includes the industry leading CC2420 IEEE 802.15.4 and ZigBee compliant RF transceiver core, 128 KB flash memory, a high performance 8051 microcontroller core and a radiolocation hardware core. The part comes in a 7 x 7 mm package, is fully pin to pin compatible to the existing CC2430 SoC and is available with the Z-Stack ZigBee protocol software from the Chipcon company, Figure 8 Wireless. This solution helps OEMs to seamlessly develop compact, high performance and reliable wireless networking products using the chip as the only active device in the system.

Motorola's radiolocation hardware core enables a CC2431-based network node to determine its own physical position in a IEEE 802.15.4/ZigBee network deployment. The core applies a proprietary algorithm based on maximum likelihood estimation, using information from infrastructure nodes to perform a location estimation. Because the algorithm is executed in a hardware core, the process of location estimation completes in less than 1/10000 second, consumes very little power and keeps the CC2431's integrated microcontroller free to perform other operations. Applications already in large scale field tests are showing a majority of results better than 2 m indoor.

The availability of this SoC solution with radiolocation feature is a strongly desired combination in wireless embedded networks. It is beneficial to applications such as asset tracking, container or pallet tracking, equipment tracking, security, access and control systems. The feature can also be advantageous in commissioning ZigBee networks.
