About two years ago, the Radio Frequency for Consumer Electronics (RF4CE) Consortium joined with the ZigBee Alliance to create a wireless protocol specifically for consumer-electronic products. Manufacturers and consumers have tired of handheld infrared (IR) controls and the "code sheet" needed to configure them. You can expect to see more handheld two-way RF4CE remote controls included with TVs, CD players, security systems, and even overhead room fans. The RF4CE protocol also appeals to manufacturers of HVAC, security, and irrigation equipment, among others, that need non line-of-sight controls. The ZigBee RF4CE devices — their official name — will adhere to a standard, so remote controls can operate many manufacturers' devices. The two-way communication capability means you'll get a "dashboard" to control home lights, door locks, heating and air-conditioning equipment, and even some appliances.
