    摘要: A communication system 100 allows for heterogeneous piconets/scattenets 100 where in multiple modes 110, 112 of transmission, one of Bluetooth 110 and one or more other modes of transmission 112 are possible. While at the same time maintaining synchronization between all the different modes of transmission 110, 112 in a given piconet and across a scatternet 100. This allows for a communication device that can communicate using a plurality of transmission modes depending on the communication needs of the device.

    摘要: A frequency hopping system such as a Bluetooth system (300) can reduce the number of RF channels it hops during a normal hopping sequence cycle providing for a Reduced Hopping Sequence (RHS). A communication unit operating in the system such as the Bluetooth master unit (302) determines if any of the RF channels has interference. If any of the channels has interference, the Bluetooth master sends a message to one or more slave units (304, 306) informing them of which channels will be removed from the hopping sequence due to potential interference problems. The units will then use the new RHS for their transmissions, thus avoiding the interference problems (e.g., both avoiding interference in the system's receivers and avoiding creating interference on frequencies that are already occupied by other neighboring systems).

    摘要: A communication circuit (28) is designed with a signal processing circuit (370) arranged to produce a first plurality of data signals and receive a second plurality of data signals. A transmit circuit (364) is coupled to receive the first plurality of data signals and transmit each data signal of the first plurality of data signals on a respective transmit frequency in a predetermined sequence of transmit frequencies. A receive circuit (362) is coupled to receive each data signal of the second plurality of data signals from a remote transmitter on the respective transmit frequency in the predetermined sequence. The receive circuit applies the second plurality of data signals to the signal processing circuit.

    摘要: A probe, listen and select (PLS) technique can be used to select from an available frequency spectrum a frequency band whose communication quality is suitable for wireless communication at a desired rate. Probe packets can be transmitted on different frequencies (223) during a known period of time (TPLS), and frequency channel quality information can be obtained (225) from the probe packets. This quality information can then be used to select a desirable frequency band (227). The communication quality of the selected band can also be used as basis for selecting (141) from among a plurality of modulation and coding combinations that are available for use in communications operations.
