The low power Bluetooth 4.0 wireless networking specification will no longer be a dream. Bluetooth SIG, the organization for setting the standard, tested, certified and licensed Bluetooth 4.0 for production and use in devices. The Bluetooth 4.0 comes as an update to the previous Bluetooth 3.0 wireless specification.
A low power transmission of a small burst of data over short distances makes it distinguishable. As the first step this will be limited only to devices that run on coin-cell batteries like watches, smart meters and pedometers. It is expected that Bluetooth 4.0 could ultimately be included in Laptops and Smartphones whereby collecting data from gadgets. This will pose as a strong contender to Wi-Fi as Wi-Fi maintains continued connectivity, thereby draining away the battery.
Several testing on chips with Bluetooth 4.0 turned successful which made the technology certified and licensed for use in chips and devices. So expect Bluetooth 4.0 devices in stores near you this year.
