Abstract:
1. A memory having instructions stored thereon that, in response to execution by a processor, cause the processor to perform operations comprising: transmitting communications to pass through a Bluetooth connection between a first device and a second mobile phone device that is different than the first device and to pass through a wireless voice channel of a wireless telecommunications network associated with the second mobile phone device; inputting a digital bit sequence into a modulator to generate an audio signal that has different frequency tones for different bit values, wherein the frequency tones are selected to pass through the wireless voice channel unobstructed by vocoders operating within the wireless telecommunications network; using the modulator, generating and sending a first transmission according to a first transmit-side power gain amount; using the modulator, generating and sending a second transmission according to a second different transmit-side power gain amount; receiving back a response indicating receive-side power gain amounts for the first and second transmissions; determining a third transmit-side power gain amount by analyzing the response; using the modulator, generating and sending a third transmission according to the third transmit-side power gain amount; discovering a Bluetooth client identifier for the second mobile phone device; and generating an entry in a table of the first device to associate the discovered Bluetooth client identifier with the third transmit-side power gain amount.
