First up is the Bluetooth Special Interest Group, which is announcing version 4.1 of its wireless communication standard. With 4.1, Bluetooth devices will be able to remember a lost connection for longer, allowing them to automatically re-establish a connection when theyre within range of one another. Bluetooth 4.1 devices will be able to act as both a peripheral and a hub, with the cited example being a smartwatch gathering information from Bluetooth Smart sensors during exercise, performing the hub role, and then passing it on to a smartphone in its capacity as a peripheral. Theres also improvement to the way Bluetooth and LTE radios coexist on the same device, with interference between the two being minimized.
