Abstract
Technologies directed to preamble detection in co-existence environments of WLAN and LR-WPAN signals are described. One wireless device has a first radio that sends a first RF signal to a second wireless device and a second radio that operates according to the IEEE 802.15.4 standard. The wireless device includes a circuit coupled between the first radio and the second radio. The circuit detects a presence of the first RF signal. The circuit receives a second RF signal from a third wireless device and attenuates the second RF signal to obtain a third RF signal in response to the presence of the first RF signal being detected. The second radio receives the third RF signal and decodes a preamble using the third RF signal.
