The present application relates to a Bluetooth communication method and a device. The method may be performed by a first device. The first device may establish Bluetooth connection with a second device. The method may include: performing link communication with the second device according to a first modulation mode; in a case where it is detected that the quality of link communication is less than a preset threshold, adjusting the modulation mode of the first device from the first modulation mode to a second modulation mode, and performing the link communication with the second device according to the second modulation mode. The anti-interference capability of the second modulation mode is greater than that of the first modulation mode.

The disclosure is related to adaptive transcoding of video streams from a camera. A camera system includes a camera and a base station connected to each other in a first communication network, which can be a wireless network. When a user requests to view a video from the camera, the base station obtains a video stream from the camera, transcodes the video stream, based on one or more input parameters, to generate a transcoded video stream, and transmits the transcoded video stream to a user device. The base station can transcode the video stream locally, e.g., within the base station, or in a cloud network based on transcoding location factors. Further, the camera system can also determine whether to stream the video to the user directly from the base station or from the cloud network based on streaming location factors.

An apparatus and a method for a wireless communication system is provided, wherein, a number of medium access control entities associated with at least one active radio link control entity of a radio bearer is determined; at least one condition for switching a state associated with the radio bearer based, at least partially, on the determined number of medium access control entities is determined; determining that the determined at least one condition for switching the state associated with the radio bearer is satisfied; and switching the state associated with the radio bearer from a first state to a second state based, at least partially, on determining that the at least one condition for switching the state associated with the radio bearer is satisfied.

A wireless microphone system is disclosed. The system includes a plurality of wireless microphones each classified in accordance with one or more audio quality parameters. The system also includes a control device communicatively coupled to the plurality of wireless microphones. The control device is configured to determine that a first wireless microphone corresponds to a first audio classification, and that a second wireless microphone corresponds to a second, different, audio classification. The control device is also configured to determine a first modulation and coding scheme for the first wireless microphone based on the first audio classification, and a second modulation and coding scheme for the second wireless microphone based on the second audio classification. The control device is further configured to transmit, to the first and second wireless microphones respectively, the determined first and second modulation and coding schemes.
