Bluetooth generally seems safe. You can easily connect your phone to your car for music or sync your fitness tracker to share data. But there are some surprising risks associated with Bluetooth that might actually disclose your location. What’s worse is that companies and law enforcement could exploit this to keep tabs on your activities without letting you know or getting a warrant.
Your phone might be watching you
Marketing technology firms, such as Leonardo US Cyber and Security Solutions, have acknowledged that Bluetooth and Wi-Fi can be used to “identify people of interest by signals emitted by electronic devices they travel with,” as noted by Signal Trace.
Its immense power can be easily exploited to subjugate virtually anyone.
Every electronic device releases signals to exchange information. Cell phones connect with nearby cell towers, Wi-Fi links to the closest router, and Bluetooth communicates with nearby devices to send or receive messages, photos, or music.
These technologies have advanced significantly. For instance, the latest Bluetooth version, 6.0, introduces highly precise location tracking, which can pinpoint a device’s location within 10 cm. Similarly, Wi-Fi 7 offers enhanced indoor location features, aiding in finding where a device is situated in a building. Together, these advances provide robust tracking capabilities that can reveal a device’s location in real time.
From a marketing viewpoint, this tech is often combined with Bluetooth Low Energy (BLE) beacons for proximity marketing. A BLE beacon is a tiny device placed next to certain products in a store. When you walk past, the beacon detects your phone and sends you a notification or discount for that product via Bluetooth. It’s an ingenious marketing approach; a bit unsettling, but seemingly harmless.
However, companies like Leonardo US Cyber and Security Solutions also gather this data and provide it to law enforcement to develop digital profiles on individuals of interest. This could include anyone—from criminal suspects to ordinary citizens.
Which devices might expose my location?
If you’re curious about which electronic gadgets are likely to compromise your location data, the unfortunate reality is that most of them could.

You can track nearly any device that has Wi-Fi or Bluetooth capabilities. Here’s a quick rundown of devices that could leak your location:
- Smartphones (like iPhones and Androids)
- Smartwatches (such as Apple Watch, Pixel Watch, Galaxy Watch, etc.)
- Fitness trackers (Fitbit, Garmin, Whoop, etc.)
- Smart rings (Oura Ring, Galaxy Ring, etc.)
- Wireless earbuds/headphones (like AirPods, Galaxy Buds, etc.)
- Smart wallets (certain models come with tracking tech to recover lost wallets)
- Tracking tags (like AirTag, Galaxy SmartTag, Tile, etc.)
- Other electronics (laptops, tablets, e-readers, etc.)
Is SignalTrace legal?
Many might wonder if this tracking method is lawful, and unfortunately, it is.
Since all Bluetooth and Wi-Fi signals from devices are publicly visible, private firms and law enforcement can slip through legal boundaries without needing warrants. SignalTrace merely captures this data to identify patterns. They can determine when devices are moving, their locations, how they frequently move together, and even track devices within buildings. All this information can be collected freely.
Leonardo US Cyber and Security Solutions claims to honor user privacy by not decrypting information gathered from targeted devices, but this doesn’t hold much weight if authorities only need to know your location for a investigative purpose.
Protecting yourself from signal tracking
Using SignalTrace, nearly any gadget can act as a tracking device. While Leonardo US Cyber and Security Solutions aims to assist law enforcement in monitoring criminals, its capabilities can just as easily be misused against anyone.
To prevent tracking through Wi-Fi and Bluetooth, the best course of action is to disable the signals on your devices. This can mean putting your device in airplane mode, locking it inside a Faraday cage to block electronic fields, or simply leaving it at home when in public.
Otherwise, you might find your phone, smartwatch, ring, or other gadget actively broadcasting your location to anyone interested.
