A method and system for managing information are provided. A grid of ring oscillator units and switches connect or disconnect the ring oscillator units to or from each other, such that the locations with low speed performance are identified according to frequencies of oscillation signals generated by rows and columns of ring oscillators respectively formed by operating the test circuit in two different modes. The mapping identifies the availability of additional vehicle identification assistance information, vehicle specific functional applets, and the context within the vehicle service software application at which the additional vehicle identification assistance information or vehicle specific functional applets are relevant. This system allows the utility company to transmit the reading of utility consumption by a consumer without the use of telephone lines.
