Abstract:
Dynamic antenna switching based on weighted signal to noise ratio (SNR). A wireless device may include multiple antennas. SNR at each active antenna may be calculated. An antenna-specific weight may be applied to each antenna's SNR. The antenna-specific weights may further be radio specific and/or transmit or receive specific in some cases. Antenna selection (possibly just for a specific radio and/or for transmit or receive operations, depending on the specificity of the antenna weights), including potentially switching which antenna is used, may be based on the resulting weighted SNR values for each antenna. If the antenna-specific weights are radio specific and/or transmit or receive operation specific, the method may be performed multiple times with different antenna-specific weights to select antenna(s) for different radios and/or for other operations.
Abstract:
Apparatus and methods for provisioning wireless devices for operation in one or more networks. In one embodiment, a provisioning service may provide access client (e.g., Subscriber Identity Module) data to a secure element in the wireless user device. The device may be preloaded with a provisioning SIM profile. The device may use the provisioning profile to roam onto a carrier, and communicate with a provisioning service, which may present the user with a list of available wireless carriers, such as carriers that service the user's current geographic location. In response to a user selection, the provisioning service may load a SIM profile associated with the selected carrier onto the secure element. The loaded SIM profile can be used to obtain wireless service from the selected carrier. The user may add multiple SIM profiles, and/or may delete SIM profiles.
