Patent Number Title Of Patent Date Issued
6973067 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
6671292 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
6650630 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
6590928 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.
6519236 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
6345066 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
6108366 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
6026297 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
