Bluetooth Special Interest Group (SIG) has announced an update to the Bluetooth Smart specification which will now include increased co-existence support for LTE and avoiding near-band interference.

The Bluetooth 4.1 release also lays the groundwork for IP-based connections, extending Bluetooth technology’s role as the essential wireless link for the Internet of Things.

“Bluetooth annual product shipment projections have increased to more than 4.5 billion in the next five years,” said Suke Jawanda, Bluetooth SIG CMO.

“We updated the Bluetooth specification to address this projected growth, making changes to give developers more control in assigning a role to their product, limiting interference with other wireless technologies, and allowing Bluetooth Smart products to exchange data faster and maintain connections with less manual intervention,” said Jawanda.

The new specification will enable Bluetooth and LTE radios to 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.

Designers ill have more control over creating and maintaining Bluetooth connections by making the reconnection time interval flexible and variable. This allows devices to reconnect automatically when they are in proximity of one another.

A single Bluetooth 4.1 device can act as both a Bluetooth Smart peripheral and a Bluetooth Smart Ready hub at the same time. For example, a smart watch acts as a hub gathering information from a Bluetooth Smart heart rate monitor while simultaneously acting as a peripheral to a smartphone.

There will also be support for bulk data transfer.
