Abstract
Adaptive guard interval calibration may be provided. A computing device may receive a first plurality of delay spread values. Each of the first plurality of delay spread values may respectively comprise an amount of time between when each of a respective first plurality Access Points (APs) receives a first tuning symbol from a first calibrating AP and when each of the respective first plurality APs receives a final multipath reflection of the first tuning symbol. Next, a first Guard Interval (GI) may be determined based on the first plurality of delay spread values. The first calibrating AP may then be provisioned with the first GI.
Claims20
A method comprising:
- receiving a first plurality of delay spread values, wherein each of the first plurality of delay spread values respectively comprises an amount of time between when each of a respective first plurality of wireless devices receives a first tuning symbol from a first calibrating wireless device and when each of the respective first plurality of wireless devices receives a final multipath reflection of the first tuning symbol;
- determining a first Guard Interval (GI) based on the first plurality of delay spread values;
- and
- provisioning the first calibrating wireless device with the first GI.
A system comprising:
- a memory storage;
- and
- a processing unit, the processing unit coupled to the memory storage, wherein the processing unit is operative to:
- receive a first plurality of delay spread values, wherein each of the first plurality of delay spread values respectively comprises an amount of time between when each of a respective first plurality of wireless devices receives a first tuning symbol from a first calibrating wireless device and when each of the respective first plurality of wireless devices receives a final multipath reflection of the first tuning symbol;
- determine a first Guard Interval (GI) based on the first plurality of delay spread values;
- and
- provision the first calibrating wireless device with the first GI.
A non-transitory computer-readable medium that stores a set of instructions which when executed perform a method executed by the set of instructions comprising:
- receiving a first plurality of delay spread values, wherein each of the first plurality of delay spread values respectively comprises an amount of time between when each of a respective first plurality of wireless devices receives a first tuning symbol from a first calibrating wireless device and when each of the respective first plurality of wireless devices receives a final multipath reflection of the first tuning symbol;
- determining a first Guard Interval (GI) based on the first plurality of delay spread values;
- and
- provisioning the first calibrating wireless device with the first GI.
