Abstract:
An apparatus for receiving signals transmitted over a wireless network in an analog mode, the apparatus comprising:first logic, the first logic receiving the transmitted signals, the first logic being configured to convert the transmitted signals into digital signals; and second logic in communication with the first logic, the second logic being configured to convert the digital signals into a sequence of bits, wherein the sequence of bits corresponds to a particular group of the transmitted signals, and wherein the group of transmitted signals are transmitted a plurality of times, thereby causing the sequence of bits to be repeated a plurality of times, said sequence of bits corresponding to a binary radio link word (RLW), the RLW comprising a first field corresponding to said first set of said sequence of bits, a second field corresponding to a second set of said sequence of bits and a third field corresponding to a third set of said sequence of bits, the third set of said sequence of bits corresponding to a data message, wherein the second logic analyzes the first sequence of bits to determine whether or not the first sequence of bits represents a continuous waveform of a particular frequency, wherein if the second logic determines that the first sequence of bits represents the continuous waveform of the particular frequency, the second logic determines that a data message is being received, wherein the data message is represented by the third set of said sequence of bits, and wherein the second logic determines whether the first set of said sequence of bits represents the continuous waveform of the particular frequency by measuring an energy level associated with a waveform produced by the first set of said sequence of bits and by measuring a level of noise associated with the continuous waveform.
