An ultra wide band communication network is provided. One embodiment ultra wide band network includes a master device and a plurality of slave devices structured to communicate with the master device using a plurality of ultra wide band pulses. The ultra wide band network also includes a medium access control protocol comprising a time division multiple access frame, the time division multiple access frame comprising a first mode for protocol exchange and a second mode for data exchange. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

Ultra wide band communication network

A wireless communication network system apparatus which provides for isochronous data transfer between node devices of the network, which provides at least one master node device which manages the data transmission between the other node devices of the network, which avoids or reduces interference from other wireless products and which resolves random errors associated with wireless technology including multipath fading. The system provides a communication protocol which shares the wireless transport medium between the node devices of the network, and which provides each node device on the network a designated transmit time slot for data communication.

Baseband wireless network for isochronous communication

A reliable Medium Access Control layer protocol and method employing centralized management of communication in a Time Division Multiple Access network architecture. The Medium Access Control layer protocol implements Quality of Service guaranties to the layers of the Open Systems Interconnection reference model above the Medium Access Control layer by providing guaranteed bandwidth links within the bandwidth range specified by those layers. The Medium Access Control layer protocol further provides variable data slot requisition, variable data slot allocation, dynamic data slot reallocation, and data slot deallocation.

Apparatus and method for managing variable-sized data slots within a time division multiple access frame

The electronic audio connection system of the present invention provides an experience much like sharing a room with several involved parties, even though the parties are physically separated. Speech enhancement and speech emphasis processing functions ensure parties perceive the speech captured in the audio signals, typically the most important portion of the captured audio signals. To capture audio signals, each space is provided a plurality of microphones arranged in that space so that the sum audio signal captured by the microphones enables the creation of a sharable audio space. Each separate physical space transmits its captured audio signals to a central server via a bi-directional data communications medium. The central server processes the summed audio signals and in turn transmits playable audio signals to each separate physical space. Speakers located in each separate physical space aurally transmit the playable audio signals. This creates an audio space shared by each of the active separate physical spaces.

Electronic audio connection system and methods for providing same

A Medium Access Control protocol software architecture which comprises a microcode component providing the protocol implementation level functions and an engine component providing hardware level functions. The Medium Access Control protocol and method for use in a network system allows for centralized management of all MAC-level services by a master device. The Medium Access Control protocol provides an improved protocol message throughput via the sequence retransmission request protocol scheme. The Medium Access Control protocol provides a reduced data transmission latency and provides dynamic allocation of data slots within a Time Division Multiple Access frame definition. The Medium Access Control protocol also provides a set of failure management functions and power control support.
