Whither Bluetooth?
Franklin Reynolds · IEEE Pervasive Computing · 2008
Almost all smart phones sold today include Bluetooth-a short-range, low-power radio technology first introduced in the late 1990s. Bluetooth-enabled accessories for phones-in particular, hands-free headsets-are also quite popular. In the less than 10 years, since version 1.0 of the Bluetooth specification was published, nearly 2 billion Bluetooth products have shipped. Here, we take a look at some of the technology improvements and new applications on the horizon. Whichever approach eventually succeeds, it's clear that lower power requirements and higher speeds for Bluetooth are coming. We expect these new technologies will rekindle interest in embedded sensors, scatternets, and the use of IP over Bluetooth-as well as new applications for mobile phones.
