Abstract: A device includes a BLUETOOTH low energy (BLE) link layer (LL) controller configured to maintain links of a link cluster between the device and one or more connected devices that share parameters associated with the link cluster and process packets associated with the links at a LL. The links of the link cluster are established according to a BLE communication standard. The parameters include coordination parameters for connection events on the links and synchronization parameters for packet transmission in the connection events. The device further includes BLE physical link (PHY) interfaces coupled to the BLE LL controller and configured to exchange the packets in the connection events on the links, interface with the BLE LL controller, and process the packets at a PHY layer according to the parameters.

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.

Abstract: Techniques for determining an angle-of-arrival of a wireless transmission are provided, including receiving, with a first antenna, at least a first portion of a wireless transmission, determining when a second portion of the wireless transmission will be received, switching to the second antenna to receive the second portion of the wireless transmission, determining an angle of arrival of the wireless transmission based on the first portion and the second portion of the wireless transmission, and outputting the angle of arrival of the wireless transmission.
