description Techniques are disclosed to leverage co-located radios such as BLE and Wi-Fi radios to increase the security of BLE ranging and localization. In one aspect, a transmitting BLE device may use a co-located Wi-Fi radio to transmit signals to interfere with an intruding device's interception of BLE RTT packets. The obfuscating Wi-Fi transmission may overlap a BLE RTT packet in the time domain with or without overlapping in the frequency domain. In one aspect, the co-located Wi-Fi radio may transmit pre-determined signature Wi-Fi signals concurrently with the BLE RTT packets to a receiver with co-located BLE and Wi-Fi radios. The receiver may detect a change in the pre-determined relationship between the two types of communication to reveal an intrusion attempt. In one aspect, a co-located Wi-Fi radio may capture parts of BLE RTT packets concurrently with a BLE radio transmitting or receiving BLE RTT packets to detect an intrusion attempt.
