One thing about the iPhone 4S that has gone relatively unnoticed is that the iPhone 4S happens to be the first available smartphone to support the Bluetooth 4.0 standard.
Bluetooth 4.0 concentrates on low-energy, sensor-filled devices that even button cell batteries could charge for instance pedometers, heart rate monitors, and home automation tools.
The Bluetooth Special Interest Group (SIG) has started promoting the technology under the new marketing term of “Bluetooth Smart.” In a press release issued today, the types of devices that Bluetooth Smart would support were outlined by Bluetooth SIG.
“The Bluetooth Special Interest Group (SIG) announced two new brand extensions to its globally recognized logo today in an effort to create consumer awareness around compatibility for new devices implementing Bluetooth v4.0 – the Bluetooth Smart Ready trademark and the Bluetooth Smart trademark. Bluetooth Smart Ready devices are phones, tablets, PCs and TVs that sit at the center of a consumer’s connected world and implement a Bluetooth v4.0 dual mode radio. Bluetooth Smart devices are sensor-type devices like heart-rate monitors or pedometers that run on button-cell batteries and were built to collect a specific piece of information. Bluetooth Smart devices include only a single-mode low energy Bluetooth v4.0 radio.”
