1 Overview
This document provides a brief overview of the On-Ramp Total Reach wireless network as well
as guidelines allowing an integrator to design a Host product that utilizes the microNode and
ensures that the system meets all of its technical objectives and requirements.
1.1 On-Ramp Total Reach Wireless Network
The On-Ramp Total Reach wireless network is comprised of microNodes and Access Points (AP).
The microNode is designed to easily integrate, through standard interfaces, with sensors
enabling robust wireless communication with one or more Access Points interfaced with a
customer’s local or wide area network.
