Abstract
A group of low power transceiver devices may create a private wireless network. In a private communication network, each device may monitor neighboring devices and transmit a low power signal on a periodic basis. At any time, if a device breaks away from the private communication network, the device determines its location and then transmits its location to one or more devices in the group at a high transmit power level.
Claims20
A computer readable storage medium comprising computer executable instructions that when executed by a computing device cause said computing device to effectuate operations comprising:
- searching, by a first device, for a signal, the signal indicative of a status of a second device;
- determining that the signal has not been detected within a first period;
- and
- responsive to the determining that the signal has not been detected within the first period,
- determining a location of the first device, and
- transmitting, at a first transmit power, an alert comprising the location to the second device, the first transmit power greater than a second transmit power of the first period.
A mobile device comprising:
- a processor;
- and
- a memory coupled with the processor, the memory having stored thereon executable instructions that when executed by the processor cause the processor to effectuate operations comprising:
- searching for a signal, the signal indicative of a status of a first device;
- determining that the signal has not been detected within a first period;
- and
- responsive to the determining that the signal from the first device has not been detected within the first period,
- determining a location of the mobile device, and
- transmitting, at a first transmit power, an alert comprising the location to the first device, the first transmit power greater than a second transmit power of the first period.
A method comprising:
- searching, by a first device, for a signal, the signal indicative of a status of a second device;
- determining, by the first device, that the signal has not been detected within a first period;
- and
- responsive to the determining that the signal has not been detected within the first period,
- determining, by the first device, a location of the first device, and
- transmitting, at a first transmit power by the first device, an alert comprising the location to the second device, the first transmit power greater than a second transmit power of the first period.
