Abstract: A cellular network includes a node configured to transmit a data packet on a predetermined frequency, first and second base stations configured to receive signals transmitted on the predetermined frequency, and a data concentrator. The first base station and the second base station are arranged in a cellular configuration such that a first coverage area of the first base station at least partially overlaps a second coverage area of the second base station. The first base station and the second base station each receive the data packet transmitted by the node. The data concentrator is configured to collect the data packet received by the first base station and the data packet received by the second base station. The data packet includes latitude and longitude data received from a global positioning system receiver such that a location of the node may be determined from a remote location.

Abstract: A phase-locked loop frequency synthesizer includes an L-state pulse width modulator configured to receive a reference frequency signal and at least one entry from a frequency table, and to output at least one N/N+1 modulus signals corresponding to the at least one entry from the frequency table. The synthesizer includes a divide by N/N+1 controllable modulus divider configured to receive the at least one N/N+1 modulus signals and to divide the output frequency signal by the at least one N/N+1 modulus signals to generate a second reference frequency signal. The synthesizer includes a phase frequency detector configured to receive the reference frequency signal and the second reference frequency signal and to generate an error signal. The synthesizer also includes a filter network configured to receive the error signal and to output a voltage; and a voltage controlled oscillator configured to receive the voltage and to generate the output frequency signal.
