I prefer cables over Bluetooth and wifi:

• Ethernet over WiFi
• USB cable over Bluetooth
• cabled headphone over Bluetooth headphone

While this increases convenience this also introduces new attack vectors (denial of service by jamming for example, tracking, or impersonation and mtm attacks).

Every person who uses wireless devices constantly emits signals into space. These can be obviously monitored, according to the laws of physics the inverse square law limits the range of such detection capabilities. Also depends on the electromagnetic noise in your environment: Jammers/other people.

• Geolocation with wifi environment.
