Abstract
A wireless network with network-level channel hopping. A wireless network includes a wireless device. The wireless device includes a receiver, a data channel selector, and a transmitter. The receiver is configured to receive a beacon signal comprising a beacon sequence value. The data channel selector is configured to select, as a pseudorandom function of the beacon sequence value, a data channel on which to transmit in an interval following reception of the beacon signal. The transmitter is configured to transmit on the data channel selected by the channel selector.
Claims20
A method, comprising:
- receiving, by a wireless device, a first beacon on a first beacon channel during a first frame, wherein the first beacon includes a first beacon sequence value;
- determining, by the wireless device, a first data channel based on the first beacon sequence value;
- transmitting, by the wireless device, a first set of data on the first data channel during the first frame;
- determining a second beacon channel based on the first beacon sequence value;
- determining, by the wireless device, a second beacon sequence value based on the first beacon sequence value;
- and
- receiving, by the wireless device, a second beacon on the second beacon channel during a second frame, wherein the second beacon includes the second beacon sequence value.
A wireless device, comprising:
- an antenna;
- a receiver coupled to the antenna, the receiver configured to receive a first beacon on a first beacon channel during a first frame, wherein the first beacon includes a first beacon sequence value;
- a data channel selector configured to select a first data channel based on the first beacon sequence value;
- a transmitter coupled to the antenna, the transmitter configured to transmit a first set of data on the first data channel during the first frame;
- and
- a beacon channel selector configured to select a second beacon channel based on the first beacon sequence value;
- and
- a control circuit configured to determine a second beacon sequence value based on the first beacon sequence value;
- wherein the receiver is configured to receive a second beacon on the second beacon channel during a second frame, and the second beacon includes the second beacon sequence value.
