Abstract
A device includes a BLUETOOTH low energy (BLE) link layer (LL) controller configured to maintain a link cluster including multiple links between the device and one or more connected devices that share parameters associated with the link cluster and to process data associated with the links of the link cluster at a LL. The links of the link cluster established according to a BLE communication standard. The device further includes or is coupled to BLE physical link (PHY) interfaces coupled to the BLE LL controller and configured to exchange the data on different links of the link cluster at different respective signal frequencies, interface with the BLE LL controller, and process the data at a PHY layer.
