IEEE's 802.1au and 802.15.4 and ZigBee are highlighted in a discussion of Renesas of Tokyo, Japan's, plan to offer a complete solution for systems houses through the development of microcontrollers, ZigBee-based RF chip sets, and single-chip devices. Renesas plans development of devices in 900MHz and 2.4GHz bands. Renesas will license RF-based intellectual property (IP) through the 802.15.4 protocol from ZMD. This will allow Renesas to develop its own 900MHz band ZigBee chip set in 2008. Then Renesas will offer a two-chip solution, including its own ZigBee chip set and a microcontroller that will be fabricated by Renesas in its fabs. In 2009, Renesas plans to develop a single-chip solution based on the ZigBee chip set and controller, and the product will be in the 900MHz band. Lastly, Renesas plans development of a separate ZigBee RF chip set in the 2.4 GHz band, but the device may not involve partnerships with Freescale. ZigBee, a short-distance wireless communications standard based on 802.11.15.4, was developed for control systems that automate homes and offices, communication applications for healthcare equipment and automated inspection systems, and data transfer between sensors. The 900MH band is being introduced mostly in Europe and North America, and ZigBee is wider in addressing 2.4GHz, to which there are two advantages: availability of multiple channels and global availability, which is crucial for ensuring acceptability.
