1. A method of increasing power efficiency and decreasing latency of communication of a mobile device operating in an unlicensed spectrum using global timing data, the method comprising:

  • receiving, at the mobile device, the global timing data from an external timing source, the mobile device communicating in the unlicensed spectrum;

    obtaining, at the mobile device, a time from the global timing data; and

    determining, at the mobile device, a wake time to switch the mobile device from a sleep state to an active state based on the time obtained from the global timing data.
