Abstract

Systems and methods for secure out-of-band wireless device management are provided. In one embodiment, a network device comprises: a wireless radio module that includes: a first wireless modem, wherein the first wireless modem communicates application data over a first wireless service; a second wireless modem, wherein the second wireless modem communicates management data over a second wireless service distinct from the first wireless service; a wireless radio module management logic programmed to manage operation of the wireless radio module based on the management data communicated using the second wireless modem.

Claims (32)

1. A network device, the device comprising:

a wireless radio module that includes:

a first wireless modem, wherein the first wireless modem communicates application data over a first wireless service;

a second wireless modem, wherein the second wireless modem communicates management data over a second wireless service distinct from the first wireless service;

a wireless radio module management logic programmed to manage operation of the wireless radio module based on the management data communicated using the second wireless modem;

a first wireless service support circuit coupled to the first wireless modem; and

a second wireless service support circuit coupled to the second wireless modem;

wherein each of the first and second wireless service support circuits includes modules that configure the wireless radio module to establish wireless network communication links over at least one wireless service of a wireless network operator.

2. The device of claim 1 , further comprising a device management security policy stored in a memory coupled to the wireless radio module management logic.

3. The device of claim 1 , wherein the radio module management logic includes security information for accessing the radio module management logic via the second wireless modem that is independent from security associated with the application data transported using the first wireless modem.

4. The device of claim 1 , wherein the wireless radio module management logic is controllable from a device management application that communicates with the wireless radio module over the second wireless service.

5. The device of claim 1 , wherein the first wireless radio modem establishes communication with an application network over the first wireless service.

6. The device of claim 1 , wherein the first wireless modem and the second wireless modem are integrated within a single digital circuit.

7. The device of claim 1 , wherein the first wireless modem and the second wireless modem comprise separate individual wireless modem circuits provided within a single form-factor of the network device.

8. The device of claim 1 , wherein at least one of either the first wireless modem or the second wireless modem are coupled to a device interface.

9. The device of claim 1 , wherein the wireless radio module management logic is implemented by a processor, a field programmable gate array (FPGA), or an application specific integrated circuit (ASIC).

10. The device of claim 1 , wherein at least one of the first and second wireless service support circuits comprise one or more subscriber identification modules (SIMs).

11. The device of claim 1 , wherein one or both of the first wireless modem and the second wireless modem are cellular modems.

12. The device of claim 1 , further comprising one or more sensor modules positioned within the device and configured to wirelessly communicate application data with an application network via the first wireless modem.

13. The device of claim 1 , further comprising at least one external data interface configured to communicate application data between one or more external devices coupled to the at least one external data interface and an application network via the first wireless modem.

14. The device of claim 13 , further comprising routing logic that routes application data communicated between the at least one external data interface and the application network.

15. A method comprising:

communicating application data between a first wireless modem within a network device and an application network via a first wireless network, wherein the first wireless modem wirelessly communicates within a first wireless service;

communicating management data between a second wireless modem within the network device and a device management server via a second wireless network, wherein the second wireless modem wirelessly communicates within a second wireless service separate from the first wireless service;

managing operation of the wireless device based on the management data, wherein managing operation comprises processing the management data at a wireless radio module management logic within the network device to adjust operation of the network device;

establishing communicating data between the first wireless modem and the first wireless network based on information provided by a first wireless service support circuit within the network device; and

establishing communicating data between the second wireless modem and the second wireless network based on information provided by a second wireless service support circuit within the network device.

16. The method of claim 15 , wherein communication via the second wireless modem is established first and the management data configures the first wireless modem for communicating application data.

17. The method of claim 15 , wherein at least one of the first and second wireless service support circuits comprise one or more subscriber identification modules (SIMs).

18. The method of claim 15 , wherein one or both of the first wireless modem and the second wireless modem are cellular modems.

19. The method of claim 15 , wherein the radio module management logic includes security for accessing the radio module management logic via the second wireless modem that is independent from security associated with the application data transported using the first wireless modem.

20. The method of claim 15 , wherein the wireless radio module management logic is controllable from a device management application that communicates with the wireless radio module over the second wireless service.
