Abstract: A method of communicating data in a Bluetooth™ low energy (BLE) module is provided. The method includes modulating an outbound communication signal into a modulated signal with a particular modulation scheme based on a modulation type, and transmitting the modulated signal to a remote device via a wireless communication connection associated with the modulation type. The method also includes receiving an inbound radio frequency (RF) signal, determining if the inbound RF signal is associated with a modulation type, and demodulating the inbound RF signal with a particular modulation scheme based on the modulation type if the inbound RF signal is determined to be associated with a modulation type. In some aspects, the inbound RF signal and outbound modulated signal have symbol rates of 2 Megasymbols per second. In some implementations, the method includes switching between a legacy BLE system and an enhanced rate BLE system.

Abstract: Protocol adaptation layer for wireless communications. Communication devices that include one or more radio modules operable in accordance with multiple communication protocols establish communications using one communication protocol and then switch to another communication protocol. This switching to another communication protocol may be performed based on a variety of factors including effectuating communications of higher throughput, supporting uni-directional communications vs. bi-directional communications, or any other desired factor. In some embodiments, various communication devices include two radio modules that are each implemented to operate in accordance with one particular communication protocol. Alternatively, a multi-protocol capable radio module may support and operate in accordance with more than one communication protocol. Examples of possible communication protocols include those compliant with Bluetooth, IEEE 802.11, and/or 802.15.3c.

Abstract: For use in offloading traffic to a wireless local area network (WLAN) a user equipment (UE) receives from a wireless wide area network at least a first set of thresholds having different thresholds corresponding to different types of data to be offloaded. The UE utilizes the threshold corresponding to a given type of data to evaluate whether an access node operating in the WLAN is suitable for offloading data of the given type. Only if the evaluated access node is determined to be suitable will the UE use it for offloading, and only for data of the given type. In other non-limiting embodiments the first set of thresholds has different thresholds corresponding to different data-types for different catergories (e.g., subscription levels) of the UE; and there may be a second set of thresholds with different thresholds corresponding to different classifications of different WLAN access nodes.
