An Ethernet network comprising multi-rate link partners that may be operable to communicate symmetrically andor asymmetrically via any of a plurality of channels. The cumulative decision statistic is determined by a sequential energy detector that includes a block energy detector that has a block termination rule, a block sampling instant and a block decision phase. In one embodiment, an example device may comprise a communication module, a plurality of antennas, at least one sensor and an antenna selection module. English, language phonetic equivalents of at least one language character including a language character intended by the user to form a word construct in a language. In a case where the index printing data generating unit cannot process a particular data file due to a shortage of remaining capacity in the memory when first index printing data is generated, the index printing data generating unit may postpone processing of the particular data file. At least one resonance is generated in a capacitive loop that exists at certain frequencies between at least two radiating elements belonging to a combination of the first set and the second set of radiating elements.
