Bluetooth is a short-range wireless communications technology intended to replace the cables connecting portable and/or fixed devices while maintaining high levels of security. The key features of Bluetooth technology are robustness, low power, and low cost.
Bluetooth enabled electronic devices transfer data; connect and communicate wirelessly through short-range, ad hoc networks known as piconets.
Each device can simultaneously communicate with up to seven other devices within a single piconet.
Each device can also belong to several piconets simultaneously. Piconets are established dynamically and automatically as Bluetooth enabled devices enter and leave radio proximity.
A fundamental Bluetooth wireless technology strength is the ability to simultaneously handle both data and voice transmissions. This enables users to enjoy variety of innovative solutions such as a hands-free headset for voice calls, printing and fax capabilities and, most importantly, synchronizing a PDA and/or laptop with a Disto A6 or Disto Plus laser measuring device.
Range: The operating range depends on the device class:
Class 3 – have a range of up to 1 meter or 3 feet
Class 2 – most commonly found in mobile devices – have a range of 10 meters or 30 feet
Class 1 – used primarily in industrial use cases – have a range of 100 meters or 300 feet: The Disto A6 and Disto Plus are Class 2 devices
Power: The most commonly used radio is Class 2 and uses 2.5 mW of power. Bluetooth technology is designed to have very low power consumption.
