3. The method of claim 2 , further comprising synchronizing, by the first UWB device, operations of first UWB device according to the beacon.
4. The method of claim 2 , wherein the beacon is received via a frame transmitted using a protocol other than a UWB protocol.
5. The method of claim 1 , wherein the second wireless communication to communicate the data is performed in the second slot of the plurality of slots.
6. The method of claim 1 , further comprising performing, by the first UWB device, a first plurality of operations to perform ranging in the first slot of the plurality of slots and performing, by the first device, a second plurality of wireless communications to communicate data in the first slot.
7. The method of claim 6 , wherein the first plurality of operations is performed in a first plurality of sub-slots of the first slot, and the second plurality of operations is performed in a second plurality of sub-slots of the first slot.
8. The method of claim 1 , comprising:
performing, by the first UWB device, the second wireless communication to communicate data at a data rate within a range of 850 kilo bits per second 100 (kbps) to 250 mega bits per second (Mbps).
9. The method of claim 8 , comprising:
performing, by the first UWB device, the second wireless communication to communicate the data at the data rate within the range by modifying at least one of a guard interval, a coding scheme, or modulation scheme.
10. A method comprising:
determining, by a first ultra-wideband (UWB) device, a transmission block comprising a plurality of rounds each representing a period of time;
performing, by the first UWB device, a first wireless communication to perform ranging between the first UWB device and a second UWB device, within a first round of the plurality of rounds, the first round of the plurality of rounds comprising a plurality of slots; and
performing, by the first device using the first UWB device, a second wireless communication to communicate data between the first UWB device and the second UWB device within a second round of the plurality of rounds, the first wireless communication performed in a first slot of the plurality of slots, and the second wireless communication performed in at least one of the first slot or a second slot of the plurality of slots.
11. The method of claim 10 , further comprising receiving, by the first UWB device, a beacon defining the transmission block.
12. The method of claim 11 , further comprising synchronizing, by the first UWB device, operations of the first UWB device according to beacon.
13. The method of claim 11 , wherein the beacon is received via a frame transmitted using a protocol other than a UWB protocol.
14. A device comprising:
a first ultra-wideband (UWB) device; and
one or more processors configured to:
determine a transmission block comprising a plurality of rounds each representing a period of time;
perform, using the first UWB device, a first wireless transmission to perform ranging between the device and a second device comprising a second UWB device, within a first round of the plurality of rounds, the first round of the plurality of rounds comprising a plurality of slots; and
perform, using the first UWB device, a second wireless transmission to communicate data between the first device and the second device within the first round, the first wireless communication performed in a first slot of the plurality of slots, and the second wireless communication performed in at least one of the first slot or a second slot of the plurality of slots.
