Methods and systems for configuring a mobile router

1. A method for sending configuration to a remote device at a server, comprising:

a. receiving sensor information from the remote device based on a trigger; wherein the sensor information is collected by the remote device; wherein the trigger is generated at the remote device when a trigger rule is satisfied; wherein the trigger rule is satisfied when any of the following conditions occur: (i) a processing unit loading of the remote device exceeds a threshold percentage, (ii) a location of the remote device changes, (iii) a clock of the remote device passes a predefined time, (iv) one of a plurality of connected cellular networks of the remote device becomes unavailable, and (v) latency of an Internet Protocol (IP) address of the remote device increases to a threshold level;

b. determining a profile from a group of profiles of the remote device;

c. retrieving a configuration based on the profile; and

d. sending the configuration to the remote device wirelessly;

wherein the remote device is a mobile router.

2. The method of claim 1 , wherein the configuration comprises information to instruct the remote device to select at least one Subscriber Identification Module (SIM) card to use; wherein the remote device comprises a plurality of SIM card slots.

3. The method of claim 1 , wherein the remote device comprises at least one wireless communication interface and at least one sensor.

4. The method of claim 1 , wherein the group of profiles comprises a low bandwidth profile, a power saving profile, a location based profile and a default profile.

5. The method of claim 4 , wherein when the low bandwidth profile is used, priorities of a few selected applications are configured to low.

6. The method of claim 4 , wherein when the power saving profile is used, the remote device is configured to reduce clock frequency of the processing unit.

7. The method of claim 1 , wherein the sensor information comprises an identity of the remote device.

8. The method of claim 1 , wherein the sensor information comprises location information or network performance information of at least one network connecting the remote device.

9. The method of claim 1 , wherein the configuration comprises a service set identifier (SSID).

10. A method for sending configuration to a remote device of a plurality of remote devices at a server, comprising:

a. proactively collecting sensor information from the remote device periodically; and

b. when there is a change of collected sensor information:

i. determining a profile from a plurality of profiles based on the sensor information; wherein: the plurality of profiles comprise a strong profile and a quiet profile; when the strong profile is used, the remote device increases air filtering rate; when the quiet profile is used, the remote device reduces air filtering rate,

ii. retrieving a configuration based on the profile; and

iii. sending the configuration to the remote device wirelessly; wherein the remote device comprises at least one wireless communication interface;

wherein:

the remote device is connected to at least one sensor through at least one input of the remote device;

the plurality of remote devices are air purifiers and placed in residential buildings.

11. The method of claim 10 , wherein the sensor information includes a number of particles detected by the at least one sensor.

12. A system for configuring a remote device, the system comprising:

a server; and

a remote device;

wherein the server comprises:

at least one network interface or at least one input;

at least one main memory;

at least one processing unit;

at least one first secondary storage storing program instructions executable by the at least one processing unit and configured to cause the at least one processing unit to:

a. receive sensor information from the remote device based on a trigger; wherein the sensor information is collected by the remote device; wherein the trigger is generated at the remote device when a trigger rule is satisfied; wherein the trigger rule is satisfied when any of the following conditions occur: (i) a processing unit loading of the remote device exceeds a threshold percentage, (ii) a location of the remote device changes, (iii) a clock of the remote device passes a predefined time, (iv) one of a plurality of connected cellular networks of the remote device becomes unavailable, and (v) latency of an Internet Protocol (IP) address of the remote device increases to a threshold level;

b. determine a profile from a group of profiles of the remote device;

c. retrieve a configuration based on the profile; and

d. send the configuration to the remote device wirelessly;

wherein the remote device is a mobile router.

13. The system of claim 12 , wherein the configuration comprises information to instruct the remote device to select at least one Subscriber Identification Module (SIM) card to use; wherein the remote device comprises a plurality of SIM card slots.

14. The system of claim 12 , wherein the remote device comprises at least one wireless communication interface and at least one sensor.

15. The system of claim 12 , wherein the group of profiles comprises a low bandwidth profile, a power saving profile, a location based profile and a default profile.

16. The system of claim 15 , wherein when the low bandwidth profile is used, priorities of a few selected applications are configured to low.

17. The system of claim 15 , wherein when the power saving profile is used, the remote device is configured to reduce clock frequency of the processing unit.

18. The system of claim 12 , wherein the sensor information comprises an identity of the remote device.

19. The system of claim 12 , wherein the sensor information comprises location information or network performance information of at least one network connecting the remote device.

20. The system of claim 12 , wherein the configuration comprises a service set identifier (SSID).
