Wibree is a wireless standard which was initially adapted from Bluetooth by Nokia. The protocol is intended to become an open standard for short range and ultra low power consumption. From June, 2007 Wibree was incorporated into the Bluetooth specification, and can be described as Bluetooth low energy technology.
Wibree is designed to complement Bluetooth technology in supported devices, while being smaller and more energy-efficient than Bluetooth. Wibree operates in 2.4GHz ISM band with gross data transfer rate of 1Mbit/s and range of 10m. The main areas Wibree is intended to target include wrist watches, wireless keyboards and toys.
Applications in which Z-Wire technology is expected to be embedded or retrofitted are lighting, home access control, entertainment systems and appliances.
TI’s proprietary SimpliciTI RF networking protocol targets simple, small RF networks with less than 100 nodes. These networks typically contain battery-operated devices, which require long battery life, low data rate and low duty cycle, and have a limited number of nodes talking directly to each other.
The protocol was designed for easy implementation with minimal microcontroller resource requirements (4K FLASH, <512byte RAM). Since SimpliciTI network protocol is designed for simple RF networks, it offers a good complement to ZigBee. The SimpliciTI network protocol supports a wide range of low-power applications including alarm and security, automated meter reading, home automation and active RFID.
Provided as source code, SimpliciTI is provided license free, without royalties and developers are encouraged to adapt the protocol to their specific application needs.
SMAC and Synkro are Freescale’s proprietary protocols based on IEEE 802.15.4. SMAC works with Freescale's transceivers with 8-bit MCU control. The protocol is intended to be used for fast product development and system evaluation. Low-cost applications that require basic primitives, such as transmit, receive and power and channel selection are examples of what SMAC can do. SMAC supports star and peer-to-peer networks, but more complex approaches can be developed, creating network layers or adding repeater nodes. SMAC can fit into 4-8 Kbyte, depending on the extra elements added.
Synkro starts with 802.15.4, but incorporates improvements in interference avoidance by adding channel agility and low latency transmissions. Synkro was created to control, monitor and automate consumer electronic products including televisions, DVD players and recorders, set top boxes, audio video receivers and remote control.
