ZigBee RF4CE Specification Now Downloadable

First announced in March 2009, the ZigBee RF4CE specification for advanced remote controls is now available for download. The spec replaces infrared with RF communication in remote controls. Thus, consumer-electronic (CE) remote controls for HDTV, home-theater equipment, set-top boxes, etc., will have greater range and longer battery life, as well as be able to operate out of line-of-sight.

RF4CE, developed by the ZigBee Alliance, enables faster, more reliable, and greater flexibility for devices to operate from longer distances. It also supports two-way communication. The spec is based on IEEE 802.15.4 MAC/PHY radio technology in the 2.4-GHz unlicensed frequency band, enabling worldwide operation, low power consumption, and instantaneous response time.

With the RF4CE wireless platform, CE manufacturers can create secure, low-cost, easy-to-deploy consumer products and features that are interoperable with other ZigBee RF4CE-certified products. Freescale Semiconductor and Texas Instruments are two companies that offer such certified platforms.
