Abstract:
1. A method for selecting an operating communication mode for carrying out a wireless communication on a communication device powered by a power pack, the method comprising: from a plurality of communication modes stored in memory, each of the plurality of communication modes having an associated voltage threshold, selecting a first communication mode as the operating communication mode and carrying out wireless communication in the operating communication mode; monitoring a present power pack voltage level of the power pack to determine if the present power pack voltage level is below the associated voltage threshold of the operating communication mode; when the present power pack voltage level is below the associated voltage threshold of the operating communication mode, selecting a second communication mode having an associated voltage threshold lower than the present power pack voltage level; and continuing to carry out the wireless communication in the second communication mode; wherein each of the communication modes comprise a first communication parameter and a second communication parameter, the plurality of communication modes are stored in an order at a first level according to the first communication parameter of the communication modes, and each of the one or more communication modes having the same first communication parameter are further ordered at a second level according to the second communication parameter.
