Techniques are disclosed to reduce latency of processing for access points using a central controller. For example, an example method of wireless communication includes receiving, at an access point, a signal wirelessly. The method further includes filtering the signal using a first passband filter having a first bandwidth to generate a first filtered signal. The method further includes filtering 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. The method further includes determining whether the signal includes a packet based on the first filtered signal and generating a control signal indicative of the determination. The method further includes transmitting the control signal and the second filtered signal to a central controller.
