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 a first beacon signal on a beacon channel during a first beacon transmission interval;
- extracting a beacon sequence value from the first beacon signal;
- selecting a data channel based on the beacon sequence value using a pseudorandom function;
- during a first contention access period of a first frame, transmitting a set of data on the data channel to a first wireless device;
- and
- during a second period after the first contention access period of the first frame, communicating with a second wireless device based on a second beacon signal different from the first beacon signal, wherein the second beacon signal is received during a second beacon transmission interval.
A method, comprising:
- receiving a first beacon signal on a beacon channel;
- extracting a beacon sequence value from the first beacon signal;
- selecting a data channel based on the beacon sequence value using a pseudorandom function;
- during a first period of a first frame, transmitting a set of data on the data channel to a first wireless device;
- and
- during a second period after the first period of the first frame, communicating with a second wireless device based on a second beacon signal different from the first beacon signal, wherein the second period comprises an inactive period of communication between the first wireless device and a third wireless device.
A method, comprising:
- receiving a first beacon signal on a beacon channel;
- extracting a beacon sequence value from the first beacon signal;
- selecting a data channel based on the beacon sequence value using a pseudorandom function;
- during a first period of a first frame, transmitting a set of data on the data channel to a first wireless device;
- and
- during a second period after the first period of the first frame, communicating with a second wireless device based on a second beacon signal different from the first beacon signal, wherein the first frame comprises communication between the first wireless device and a third wireless device, and a second frame comprises communication between the second wireless device and the third wireless device.
A system comprising:
- a first wireless device configured to:
- receive a first beacon signal on a first beacon channel;
- select a first data channel using a first beacon sequence value indicated by the first beacon signal;
- transmit first data on the first data channel during a first period of a frame;
- and
- transmit a second beacon signal to a second wireless device on a second beacon channel, the second beacon signal including a second beacon value;
- and
- the second wireless device configured to:
- receive a third beacon signal on a third beacon channel from the first wireless device during a second period of the frame;
- select a second data channel using a third beacon sequence value of the third beacon signal;
- and
- transmit second data on the second data channel during the second period of the frame;
- wherein the first wireless device is not transmitting during the second period.
