Multi-media protocol for slot-based communication systems |
December 6, 2005 |
| A method and apparatus are described establishing multimedia communications on a shared communications channel. A first and a second communication unit, such as a master and slave unit, establish a synchronous communications link. Additional synchronous communications links may be es |

Method and system for adaptive voice buffering |
December 30, 2003 |
| A system and method for adaptive voice buffering is disclosed. In a voice transmitter, a ring buffer uses read and write pointers to implement changes in the delay of a communication link. The receiver also implements a ring buffer having read and write pointers to buffer incoming digiti |

Resource management and traffic control in time-division-duplex communication systems |
November 18, 2003 |
| A system and method for resource management and traffic control in time division duplex communication systems is discloses. A multi-radio base station maintains communication links with a plurality of remote terminals, each of which requests a specific bandwidth ratio. A controller a |

Frequency hopping piconets in an uncoordinated wireless multi-user system |
July 8, 2003 |
| A wireless network includes master and slave units. The master sends a master address and clock to the slaves. Communication is by means of a virtual frequency hopping channel whose hopping sequence is a function of the master address, and whose phase is a function of the master clock. |

Automatic power control in uncoordinated frequency-hopping radio systems |
February 11, 2003 |
| Transmission power in a frequency-hopping radio system that transmits packets from a sending radio unit to a receiving radio unit, wherein each packet includes an address designating the receiving radio unit, is controlled by measuring received signal strength of packets whose addres |

Reduction of access time delay in frequency-hopping radio systems using a direct sequence mode |
February 5, 2002 |
| In a radio system that employs frequency hopping (FH), access time delay is reduced, without compromising processing gain, by adding direct-sequence (DS) spreading to the system. This results in a hybrid FH/DS system, wherein the use of DS spreading permits a reduction in the number of h |

Method and apparatus for the generation of frequency hopping sequences |
August 22, 2000 |
| A frequency hopping generator comprises an XOR processing module and a PERM (permutation) processing module arranged in series. The XOR and PERM modules act directly on input clock lines as a function of a selection address. The hopping number sequence generated by the frequency hopping |

Contemporaneous connectivity to multiple piconets |
February 15, 2000 |
| A first wireless unit engages in contemporaneous participation in a plurality of wireless networks. A connection is established with a second wireless unit in a first wireless network. Then, a hold time-out period is determined, and the first wireless unit enters a hold mode with respect |
