Method and system for locating and communicating with a user of a wireless communication device
A system and method provides a notification to a user via a wireless communication device when the wireless communication device leaves a predetermined area. Components within the wireless communication device are utilized to determine the location of the wireless communication device. When the wireless communication device is no longer within the predetermined area, a notification is provided to the user.
1. A method for maintaining communication by switching a mobile device between first and second wireless communication signals, comprising:
determining, within the mobile device, a threshold change in the first wireless communication signal and then switching the mobile device to the second communication signal;
wherein the first wireless communication signal and the second wireless communication signal originate from different types of transmitters.
2. The method of claim 1 , wherein determining comprises determining a distance.
3. The method of claim 2 , further including the steps of storing, in non-transitory memory, data indicative of a boundary around the source of the first wireless communication signal and comparing the distance to the data indicative of a boundary to determine that the mobile device passes the boundary.
4. The method of claim 3 , further providing, from the mobile device, instructions to a user of the mobile device when the mobile device passes the boundary.
5. The method of claim 4 , the instructions comprising one or more of a displayed instructions, vibrational instructions, and audible instructions.
6. The method of claim 1 , wherein each of the first and second wireless communication signals is selected from the group consisting of a IEEE 802.11 signal, a IEEE 802.16 signal, a cellular network signal, a WLAN signal, a Satellite communication signal, a GPS signal, and a WAN signal.
7. The method of claim 1 , wherein the mobile device switches to the second communication signal when the first communication signal is attenuated.
8. The method of claim 1 , further comprising initiating a scan to identify an available communication signal based upon the threshold change and selecting the available communication signal to be the second wireless communication signal.
9. The method of claim 1 , further comprising establishing a connection with both the first and second communication signal and wherein switching the mobile device to the second communication signal is selecting the second communication signal.
10. The method of claim 2 , wherein determining a distance comprises determining a distance based upon signal strength of the first communication signal for the threshold change.
11. The method of claim 2 , wherein determining a distance comprises determining a distance based upon pulse modulation time differential of the first communication signal for the threshold change.
12. The method of claim 2 , wherein determining a distance comprises determining a distance based upon phase shift of the first communication signal for the threshold change.
13. The method of claim 1 , further comprising:
scanning, by the mobile device, to identify one or more available wireless communication signals.
14. The method of claim 13 , further comprising:
selecting one of the identified one or more available wireless communication signals to be the second wireless communication signal.
15. The method of claim 1 , further comprising:
determining, within the mobile device, a threshold change associated with the second wireless communication signal;
scanning, by the mobile device, to identify a third wireless communication signals; and
switching the mobile device to the third communication signal.
16. A method for switching a mobile device between first and second wireless tether signals, comprising:
determining, within the mobile device, a threshold change in the first wireless tether signal and then switching the mobile device to the second tether signal;
wherein the first wireless tether signal and the second wireless tether signal originate from different types of transmitters, and
wherein the first and second wireless tether signals utilized in determining a location of the mobile device.
17. The method of claim 16 , wherein the mobile device utilizes one or both of the first and second wireless tether signals to determine the location of the mobile device.
18. The method of claim 16 , wherein a second device controlled by a third party utilizes one or both of the first and second wireless tether signals to determine the location of the mobile device.
19. The method of claim 16 , wherein the first and second wireless tether signals utilized in determining a location of the mobile device are selected from the group consisting of a IEEE 802.11 signal, a IEEE 802.16 signal, a cellular network signal, a WLAN signal, a Satellite communication signal, a GPS signal, and a WAN signal.
