1. A wireless vehicular sensor node, comprising:
- said wireless vehicular sensor node configured to use a state from a sensor to create a waveform and a waveform characteristic based upon said sensor observing the presence of a vehicle; and
said wireless vehicular sensor node configured to operate a wireless transmitter based upon said waveform characteristic to send a report across at least one wireless physical transport to approximate said waveform.

Abstract
The invention includes using multiple wireless vehicular sensor nodes to wirelessly receive multiple, time-interleaved vehicular waveform reports from the nodes. Each vehicular waveform report approximates a raw vehicular sensor waveform observed by a magnetic sensor at the node based upon the presence of a vehicle. The vehicular waveform reports are products of this wirelessly receiving process. The invention includes apparatus supporting the above outlined process. The vehicular waveform reports may be time synchronized.

5. An access point for wirelessly communicating with a first wireless vehicular sensor node and a second wireless vehicular sensor node, and comprising:
-
said access point configured to wirelessly receive a first report from said first wireless vehicular sensor node time-interleaved with a second report from a said second wireless vehicular sensor node; wherein said first report approximates a first waveform created by a first sensor observing the presence of a first vehicle; wherein said second report approximates a second waveform created by a second sensor observing the presence of a second vehicle; wherein said first wireless vehicular sensor node operates said first sensor; and
wherein said second wireless vehicular sensor node operates said second sensor. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 17, 18)
