Wibree


Wibree, já ouviram falar? pois é uma tecnlogia a ser lançada pela Nokia e semelhante ao Bluetooth cria zona de conexão de baixa cobertura. Na verdade, essas dua tecnologias não serão concorrentes mas complementares, uma vez que o Wibree trabalha com cargas menores de energia e os chips são mais compactos:

"Both Wibree and Bluetooth allow devices to communicate via short-range radio signals. Bluetooth can be used to perform a variety of tasks, including sharing files between a PC and a PDA, downloading an address book into a cell phone from a PC, and transmitting a signal from a remote control to a television. The Bluetooth radio operates at 2.4 GHz, "hopping" rapidly around different bands close to that frequency to provide security and resistance to interference from other signals (see How Bluetooth Works to learn more). Wibree, it turns out, will use the same radio frequency as Bluetooth, a major advantage over competitors. Using the same basic mechanism for wireless communication will make it much easier for devices to build in both Wibree and Bluetooth compatibility."
