摘要： A method and system for Bluetooth® and Wireless LAN coexistence may include controlling wireless local area network (WLAN) communication and Bluetooth® communication in a coexistence system that handles at least a WLAN communication protocol and a Bluetooth® communication protocol based on time division multiplexing (TDM) and adaptive frequency hopping (AFH). Switching may occur between the WLAN communication and the Bluetooth® communication based on the TDM and the AFH. In one embodiment of the invention, the switching may occur adaptively. Notwithstanding, in instances where it may be determined that AFH is disabled, switching to TDM may occur. WLAN communication and/or Bluetooth® communication may be disabled or enabled based on a state of at the WLAN communication and/or the Bluetooth® communication. Use of the AFH may be enabled or disabled based on a link status of the WLAN communication and/or the Bluetooth® communication.

The first and second RF circuits are co-located and the first RF circuit is configured to operate in a first frequency range. The second RF circuit is configured to operate in a second frequency range, where the first frequency range overlaps, at least in part, the first frequency range. The method initiates with a controller that is coupled to the first RF circuit and the second RF circuit. Then, the second RF circuit is configured to avoid RF signal collisions with the first RF circuit. An apparatus where two RF devices are co-located without causing interference for each other is also provided.

摘要： Methods, systems, and apparatuses for synchronizing one or more output/sink devices are described. In each sink device, a communication packet is received from a source device. The communication packet includes data and a source clock timestamp. A local clock signal is generated that is synchronized with a source clock signal of the source device. The data is decoded using a codec. At least one delay and the source clock timestamp are subtracted from a current value of the local clock signal to generate a local latency value. A difference between a desired latency value and the local latency value is determined. A rate of a clock signal of the codec is adjusted according to the determined difference. Because each sink device adjusts its latency to a common desired latency value, the sink devices are thereby synchronized.

摘要： Aspects of a method and system for fast and reliable channel classification in Bluetooth networks to detect and avoid channel interferers may include one or more processors that may enable performance of signal strength measurements on received Bluetooth signals at a current selected frequency. At least one data packet received via the Bluetooth signals may be processed to determine the presence of bit errors. The processor(s) may enable characterization of the Bluetooth signals at the current selected frequency based on the signal strength measurements and/or the processing of the data packets. The current selected frequency may be selected during adaptive frequency hopping based on the characterization.

摘要： A method for avoiding signal interference between a first RF device and a second RF device is provided. The first and second RF devices are co-located and the first RF device is configured to operate within a semi-stationary range of a frequency band. The second RF device is configured to operate by changing channels within the frequency band. The method initiates with a communication interface being provided between the first RF device and the second RF device. Then, the second RF device receives the semi-stationary range and a mode for the first RF device through the communication interface. Next, the second RF device is adapted to avoid the semi-stationary range of the frequency band of the first RF device when the mode of the first RF device is in an active mode. An apparatus where two RF devices are co-located without causing interference for each other is also provided.
