1. A vehicle toll module, comprising:
a first antenna configured to receive a first signal from a toll collection system remotely located relative a vehicle and generate a first output based, at least in part, on the received first signal;
a radio frequency power detector communicatively connected to the first antenna and configured to adjust the first output and generate a second output based, at least in part, on the adjusted first output;
an attenuator communicatively connected to the first antenna and configured to: receive the second output, and generate a third output based, at least in part, on the received first output; and
a controller communicatively connected to the attenuator and configured to:
receive the third output,
extract data from the second output, and
generate a fourth output based, at least in part, on a unique identifier associated with the vehicle toll module, in response to the extracted data;
wherein the third output is at least one of:
received by a second antenna, which is configured to transmit a second signal based, at least in part, on the received third output, the second signal including a unique identifier and operable to be received by the toll collection system, and
received by the first antenna, which is further configured to backscatter the first signal based, at least in part, on the received third output, the backscattering of the first signal operable to provide the unique identifier.
