We bring together the most relevant Electronics Weekly content on a range of wireless technologies:
Note: "Wibree" became known as "Ultra Low Power (ULP) Bluetooth" and then also became "Bluetooth low energy"
Wibree - which is now known as Ultra Low Power (ULP) Bluetooth, or even Bluetooth low energy - is radio technology for small, button cell battery-powered devices, such as watches, wireless keyboards, and gaming and sports sensors. These objects can then connect to Bluetooth-enabled host devices, whether computers or mobile phones.
Developed by Nokia from 2001, and released publicly in 2006, Wibree extends the range of devices that can accommodate wireless comms, and it is intended to drive growth in the mobile device market. Using a 2.4 GHz frequency, it supports a bit rate of 1 Mbit/sec.
Potentially, it could play a part in Bluetooth becoming the de facto wireless technology for the last 25 metres of the wireless Internet.
As its name suggests, the ultra low power Bluetooth is intended for applications where low power consumption and low cost are the major requirements. Its proponents argue that it is complementary, and not a rival, to existing Bluetooth technology, which is more suited for data streaming and file transfers.
Note that Wibree became ULP Bluetooth in June 2007, and it has two forms of implementation: stand-alone and dual-mode, which uses a combination of Wibree and Bluetooth technology.
Whereas the likes of watches and sensors will typically be based on a stand-alone implementation, more traditional Bluetooth-enabled devices, for example smartphones, could use dual-mode implementation to extend Bluetooth connectivity to new, smaller devices.
Both modes would share one physical radio and antenna, and a dual-mode device that connected to a stand-alone 'Wibree' device would enjoy lower power consumption.
To complete the mix of RF technologies, there is also ZigBee. This is a low-power networking technology supporting thousands of nodes, whereas ULP Bluetooth would link a small number of nodes to a host device, such as computer or phone.
