First Claim
1. A mobile communication device comprising:
- a first module operable to communicate information according to each of a plurality of communication protocols, each communication protocol described by a plurality of non-informational characteristics;
a second module operable in a plurality of modes comprising;
a first mode described by sleep mode characteristics; and

Abstract
A mobile communication device comprising a low power signal detector and a manner of utilizing a low power signal detector in a mobile communication device. Various aspects of the present invention may comprise a first module adapted to receive a communication signal. A second module may be adapted to operate in a plurality of operating modes, comprising a first mode and a second mode. The first mode may, for example, comprise characteristics of a sleep mode. The second module may, in the second mode, process the received communication signal (e.g., determining information communicated by the received communication signal). A third module may be adapted to determine, based at least in part on a non-informational characteristic of the received communication signal, whether to operate the second module in the first mode or in the second mode.

15. In a mobile communication device comprising a first module adapted to operate in a first mode described by sleep mode characteristics, and a second mode in which the first module processes a communication signal to determine information being communicated by the communication signal, a method for operating the mobile communication device, the method comprising:
-
operating the first module in the first mode; receiving the communication signal; analyzing non-informational characteristics of the received communication signal and not information being communicated by the received communication signal to determine whether to transition operation of the first module from the first mode to the second mode to process the received communication signal; and if it is determined to operate the first module in the second mode, then operating the first module in the second mode to process the received communication signal, wherein the analyzing comprises determining whether to transition operation of the first module from the first mode to processing the received communication signal during the second mode-based, at least in part, on whether the non-informational characteristics comprise a spectral signature and a modulation technique associated with a particular communication protocol. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
