System for large area telemetry data collection networks
First Claim
1. A data collection network comprising:
- a plurality of communication nodes forming a Mesh network, at least a plurality of the communication nodes each being battery powered and each coupled to a sensor for communicating the output of the sensor over the network, the Mesh network being coupled in communication with a base station, nodes forming the Mesh network being synchronized for synchronized communication separated by longer periods of inactivity for conservation of battery power, anda wireless backbone of a plurality of powered nodes wherein the powered nodes comprise a plurality of communication nodes disposed in streetlight photo sensor sockets and also duplicating the function of the streetlight photo sensor.

Abstract
System for large area such as citywide telemetry data collection networks using a Mesh network of nodes including a backbone network of nodes, usually powered, and a plurality of sensor nodes, usually battery operated, in the Mesh network to communicate directly or indirectly through other such nodes, to one or more backbone nodes. Power consumption is held very low for the battery powered nodes by only requiring communication over very short distances, and by synchronizing operation of the system with a low duty cycle. The system may be self configuring, such as by using the Ad hoc On Demand Distance Vector routing protocol. Two way communication is possible for control and other purposes. Various applications and possible features are disclosed.
