Abstract

A method is provided for transmitting wireless signals in a network comprising a network coordinator and one or more remote devices. The available transmission time is divided into a plurality of superframes, each of which is further divided up into a beacon duration, one or more management time slots, one or more guaranteed time slots, and one or more asynchronous time slots. Each of the management time slots, guaranteed time slots, and asynchronous time slots are assigned to one of the one or more remote devices. The network coordinator sends a beacon to the one or more remote devices during the beacon duration. The device or coordinator assigned to the current guaranteed time slot sends frames of isochronous data in the current guaranteed time slot. The device or coordinator assigned to the current asynchronous time slot sends frames of asynchronous data in the current asynchronous time slot.

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;
dividing each of the plurality of superframes into a beacon duration, one or more management time slots, one or more guaranteed time slots, and one or more asynchronous time slots;
assigning each management time slot to one of the one or more remote devices;
assigning each guaranteed time slot to one of the one or more remote devices or to the network coordinator;
assigning each asynchronous 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 a current asynchronous time slot from the one or more remote device or network coordinator assigned to the current asynchronous time slot.
