Latest Bluetooth® 4.1

The updated Bluetooth 4.1 improves consumer usability for increasing support for LTE, data exchange rates (bulk ), and also for aid developer innovation. It allows devices to support multiple roles that also lays the groundwork for IP-based connections. This will broaden Bluetooth's technologies  role as the essential wireless link of the Internet of Thing (IoT). 

Bluetooth 2.0 update to Bluetooth 4.1

3 Major Improvements:
  • Coexistenceengineered to work seamlessly and cooperatively with the latest generation cellular technologies like LTE. Bluetooth and LTE radios can communicate in order to ensure transmissions are coordinated and therefore reduce the possibility of near-band interference. The coordination between the two technologies happens automatically, while the consumer experiences the high quality they expect.
  • Better Connections provides manufacturers with more control over creating and maintaining Bluetooth connections by making the reconnection time interval flexible and variable. This improves the consumer experience by allowing devices to reconnect automatically when they are in proximity of one another. The consumer can leave the room and upon returning, two recently used devices reconnect without user intervention.
  • Improved Data TransferBluetooth Smart technology provides bulk data transfer. For example, through this new capability, sensors, which gathered data during a run, bike ride or swim, transfer that data more efficiently when the consumer returns home.
