12. The system of claim 1 , further comprising a sensor to measure motion data associated with motion of the system, and wherein the WLAN is to send the motion data or an indication based on the motion data to at least some of the plurality of network controllers to cause the at least some of the plurality of network controllers to enter a lower power state for power saving.

13. The system of claim 1 , wherein a given network controller of the plurality of network controllers is to save session information that is available across a power cycle of the given network controller, the given network controller to use the saved session information when powering up to establish a session represented by the saved session information.

14. The system of claim 13 , wherein the saved session information comprises a security key and a network address.

15. The system of claim 1 , wherein the first network controller maintains synchronized links with multiple network controllers of the plurality of network controllers, the first clock is a master clock, and the multiple network controllers comprise respective clocks synchronized to the master clock.

16. A method comprising:

communicating data between a first network controller and a second network controller over a wireless local area network (WLAN) in a system, wherein the first network controller comprises a first clock to produce a first oscillating signal, and the second network controller comprises a second clock to produce a second oscillating signal, wherein a link between the first network controller and the second network controller through the WLAN is a synchronized link based on transition edges of the first oscillating signal being aligned in time with transition edges of the second oscillating signal;

storing, in a respective first queue of each of the first network controller and the second network controller, data according to a real-time access class that is to be communicated between the first network controller and the second network controller over the synchronized link; and

storing, in a respective second queue of each of the first network controller and the second network controller, non-real-time access class data that is to be communicated between the first network controller and the second network controller over a further link separate from the synchronized link.
