8. The system of claim 1 , wherein the communication circuit is to receive additional wireless network information from at least one of the plurality of devices in the wireless environment.
9. The system of claim 8 , wherein the additional wireless network information comprises received signal strengths of devices in the wireless environment around the least one of the plurality of devices in the wireless environment.
10. The system of claim 8 , further comprising a wireless analysis circuit to use the additional wireless network information from the at least one of the plurality of devices in the wireless environment along with the wireless network information obtained by the wireless access point device to determine a location of the at least one of the plurality of devices in the wireless environment.
11. The system of claim 10 , wherein to determine the location, the wireless analysis circuit is to use a free space loss calculation to determine distances between pairs of devices in the wireless environment and using trilateration techniques to determine position from the distances between the pairs of devices.
12. The system of claim 1 , wherein the remote mobile user device is associated with a responder classification.
13. The system of claim 12 , wherein the responder classification is a professional responder, a helper, or a predesignated responder.
14. The system of claim 12 , wherein the communication circuit is to receive instructions from the cloud service, the instructions based on the responder classification.
15. At least one non-transitory machine-readable medium including instructions, which when executed by a machine, cause the machine to:
receive, at a wireless access point device, input indicating an alert event, the input received from a remote mobile user device, the input initiated by a user of the remote mobile user device; and
in response to receiving input indicating an alert event:
obtain wireless network information of a wireless environment around the wireless access point device, wherein the wireless network information includes wireless access point devices and mobile user devices;
generate a message including the wireless network information;
transmit the message and the alert event to a cloud service; and
broadcast, from the wireless access point device to a plurality of devices in the wireless environment, the wireless network information of the wireless environment around the wireless access point device.
16. The at least one non-transitory machine-readable medium of claim 15 , wherein the instructions to transmit information regarding the alert event comprise instructions to:
transmit an identity of a user of the remote mobile user device; and
transmit information about the wireless environment around the remote mobile user device.
17. The at least one non-transitory machine-readable medium of claim 16 , wherein the instructions to transmit information about the wireless environment comprise instructions to transmit wireless signal strengths of devices in the wireless environment.
18. The at least one non-transitory machine-readable medium of claim 16 , wherein the instructions to transmit information about the wireless environment comprise instructions to transmit media access control (MAC) addresses of devices in the wireless environment.
19. The at least one non-transitory machine-readable medium of claim 15 , wherein the wireless network information comprises channel state information of devices in the wireless environment around the wireless access point device.
20. A method of using a personal safety system, the method comprising:
receiving, at a wireless access point device, input indicating an alert event, wherein the input is received from a remote mobile user device, and initiated by a user of the remote mobile user device; and
in response to receiving input indicating an alert event:
obtaining wireless network information of a wireless environment around the wireless access point device, wherein the wireless network information includes wireless access point devices and mobile user devices;
generating a message including the wireless network information;
transmitting the message and the alert event to a cloud service; and
broadcasting, from the wireless access point device to a plurality of devices in the wireless environment, the wireless network information of the wireless environment around the wireless access point device.
21. The method of claim 20 , further comprising receiving additional wireless network information from at least one of the plurality of devices in the wireless environment.
22. The system of claim 1 , wherein the alert event of the input comprises a crime, a natural disaster, or an emergency situation.
23. The at least one non-transitory machine-readable medium of claim 15 , wherein the alert event comprises a crime, a natural disaster, or an emergency situation.
