receiving an indication from the external computing entity to utilize the first training field for the preamble.

6. An access point comprising:

a receiver configured to receive a signal wirelessly;

a processor configured to:

filter the signal using a first passband filter having a first bandwidth to generate a first filtered signal;

filter the signal using a second passband filter having a second bandwidth to generate a second filtered signal, wherein the first bandwidth is less than the second bandwidth; and

determine whether the signal includes a packet based on the first filtered signal and generating a control signal indicative of the determination.

7. The access point of claim 6 , wherein:

the receiver is further configured to receive a plurality of samples from an external computing entity;

the processor is further configured to:
