Radio Frequency for Consumer Electronics (RF4CE) is a radio frequency standard that was created for remote control devices for consumer electronics. The technology is based on 2.4 GHz IEEE® 802.15.4 MAC/PHY radio technology. 

ZigBee RF4CE was introduced to replace IR remote control technology and overcome its limitations like interoperability, line-of-sight, and limited features. The specification creates a remote control network layer that allows for simple, low-power, low-latency communication for a wide range of products including home entertainment devices, garage door openers and keyless entry systems, based on the IEEE 802.15.4 specification. It provides two-way RF communication that ensures interoperability between remote controls and audio/visual (A/V) devices.

The RF4CE specification was standardized in 2009 by a consortium that includes Panasonic, Philips, Sony and Samsung. And is now a part of ZigBee Alliance®.

Characteristics of Zigbee RF4CE Include:

• Operation in the 2.4 GHz frequency band according to IEEE 802.15.4
• Co-existence with other 2.4 GHz technologies
• Frequency agile solution operating over three channels
• Incorporates power saving mechanisms for all device classes
• Discovery mechanism with full application confirmation
• Pairing mechanism with full application confirmation
• Multiple star topology with inter-personal area network (PAN) communication
• Various transmission options including broadcast
• Security key generation mechanism
• Utilizes the industry standard AES-128 security scheme
• Specifies a simple remote control profile for consumer electronics products
• Support Alliance developed standards or manufacturer specific profiles
