Abstract:
1. A method of transmitting wireless signals in a network comprising a network coordinator and one or more remote devices, comprising: dividing up available transmission time into a plurality of superframes; assigning only a single remote device chosen from the one or more remote devices to each of the plurality of superframes; dividing each of the plurality of superframes into a beacon duration, one or more management time slots, and one or more guaranteed time slots; assigning each management time slot to the single chosen remote device in a corresponding one of the plurality of superframes; assigning each guaranteed time slot to one of the one or more remote devices or to the network coordinator; sending a beacon from the coordinator to the one or more remote devices during the beacon duration of each of the plurality of superframes; sending one or more frames of isochronous data in a current guaranteed time slot from the one or more remote device or network coordinator assigned to the current guaranteed time slot; and sending one or more frames of asynchronous data in at least one of the one or more management time slots from either the network coordinator or the single chosen remote device in the corresponding one of the plurality of superframes, wherein the assigning of the single remote device chosen from the one or more remote devices to each of the plurality of superframes takes place during the beacon assigned to the respective superframe, and wherein the wireless signals are ultrawide bandwidth signals.
