Methods for enabling localization; related electronic devices and related location server devices

A positioning unit comprising a memory circuitry, a processor circuitry, and an interface, wherein the positioning unit is configured to communicate with a location server device, and with an electronic device,

• wherein the interface is configured to transmit, to the electronic device, one or more first positioning signals at a first frequency;
• wherein the interface is configured to detect an activation trigger, wherein the activation trigger indicates to the positioning unit to activate transmission of one or more second positioning signals;
• and
• wherein the interface is configured to transmit, to the electronic device, the one or more second positioning signals at a second frequency that is different from the first frequency.

An electronic device comprising a memory circuitry, a processor circuitry, and a wireless interface, wherein the electronic device is configured to communicate with one or more positioning units,

• wherein the wireless interface is configured to receive, from the one or more positioning units, one or more first positioning signals at a first frequency;
• wherein the processor circuitry is configured to activate a receiver circuitry of the wireless interface for reception of the one or more second positioning signals at a second frequency different from the first frequency;
• and
• wherein the wireless interface is configured to receive, from the one or more positioning units, the one or more second positioning signals at the second frequency.
