Using wireless networks for locationing and data transfer
In some implementations, a locating agent may identify, at the locating agent, one or more identifiable access points, each identifiable access point establishing a wireless network and being identifiable to the locating agent via a signal broadcast from the identifiable access point. The locating agent may compare the identified one or more identifiable access points to an access-point database defining known access points to the wireless tracking system. The locating agent may connect to one of the identifiable access points based on the comparing. The locating agent may transmit one or more of sensed and monitoring data captured at the locating agent to an external device via the connected access point.
1. A method for identifying an access point for connection by a locating agent of a wireless tracking system, comprising:
downloading a local portion of an access-point database from a server, the local portion corresponding to a general region that the locating agent is expected to be located in;
storing the downloaded local portion on a memory of the locating agent;
identifying, at the locating agent, one or more identifiable access points, each identifiable access point establishing a wireless network and being identifiable to the locating agent via a signal broadcast from the identifiable access point;
comparing the identified one or more identifiable access points to the local portion of the access-point database defining known access points to the wireless tracking system;
connecting to a first access point of the identified one or more identifiable access points based on the comparing; and
transmitting one or more of sensed and monitoring data captured at the locating agent to an external device via the first access point.
2. The method of claim 1 , the identifying comprising identifying a respective SSID broadcast by each identifiable access points.
3. The method of claim 1 , the identifying including determining a received signal strength corresponding to each access point.
4. The method of claim 1 , the comparing including identifying a connection access point list prioritizing at least some of the identifiable access points for selection as the first access point to connect with by the locating agent.
5. The method of claim 4 , the local portion of the access-point database including an authorized access points list, a verified access points list, and an unusable access points list; the identifying a connection access point list including prioritizing each of the identifiable access points based on at least one of the authorized access points list, the verified access points list, and the unusable access points list.
6. The method of claim 1 , the local portion of the access-point database defining white-listed access points that are defined as safe to connect with and black-listed access points that are not-to-be connected with.
7. The method of claim 4 , the identifying a connection access point list including prioritizing each of the identifiable access points based on prior connection success with at least one other locating agents.
8. The method of claim 1 , further comprising determining a location of the locating agent based on the identifiable access points; and receiving an update to the local portion of the access-point database when the location indicates the locating agent has crossed a pre-defined geofence.
9. The method of claim 1 , further comprising:
storing a connection history of the locating agent to at least one of the identifiable access points; and
transmitting the connection history to another device.
10. The method of claim 1 , further comprising:
identifying one or more of the identifiable access points as an unknown access point without known connection information within the local portion of the access-point database;
guessing connection information for the unknown access point; and
transmitting the guessed connection information to another device when the connection information is successful in connecting the locating agent to a network associated with the unknown access point.
11. The method of claim 1 , further comprising:
communicating over a cellular network when connection to the first access point is unavailable;
when communicating over the cellular network, implementing a connection governor; and
when the first access point is a Wi-Fi access point and communicating via the first access point is available, reducing the connection governor.
12. A method for determining location of a locating agent of a wireless tracking system, comprising:
identifying, at the locating agent, one or more access points from one or more identifiable access points, each identifiable access point establishing a wireless network; and
comparing an access point characteristic of each of the identified one or more access points to known access point information to determine the location of the locating agent, wherein the known access point information is populated based on a planned itinerary for the locating agent.
13. The method of claim 12 , further comprising, when the location indicates the locating agent has passed a geofence, transmitting an alert to an another device.
14. The method of claim 13 , further comprising, after transmitting the alert to the another device, receiving an update to the known access point information, the update including additional known access points based on the geofence passed.
15. The method of claim 13 , further comprising:
comparing the identified one or more access points to a known access point list corresponding to the planned itinerary; and
when the identified one or more access points do not correspond to the known access point list, transmitting an off-course alert.
16. The method of claim 15 , wherein the identified one or more access points do not correspond to the known access point list when none of the identified one or more access points match an access point in the known access point list.
17. The method of claim 15 , wherein the identified one or more access points do not correspond to the known access point list when less than a threshold number of known access points in the known access point list match a respective one of the identified one or more access points.
18. The method of claim 15 , wherein transmitting an off-track alert includes activating a cellular communication device to transmit the off-course alert.
19. The method of claim 12 , wherein the comparing an access point characteristic of each of the identified one or more access points to known access point information to determine the location of the locating agent occurs without connecting to a network established by one of the identified one or more access points.
20. A method for configuring a mesh network within a building, comprising:
identifying existing access points identifiable by a locating agent within the building, the existing access points operating according to a first communication protocol;
generating a no-connection list indicating when the locating agent cannot access the identified existing access points;
comparing a location of the locating agent to the no-connection list to identify a network void spot within the building; and
after the comparing, updating an access point list with information regarding an infrastructure node corresponding to the network void spot, the infrastructure node having a second communication protocol different than the first communication protocol.
21. The method of claim 20 , the adding including updating the infrastructure node in a known access point list.
22. The method of claim 21 , further comprising, utilizing the infrastructure node to locate the locating agent.
23. The method of claim 20 , wherein the existing access points operate according to a first service, and the infrastructure node operates according to a second service different from the first service.
24. The method of claim 23 , the second service being a dedicated network requiring registration thereto.
