1 Introduction This document describes On-Ramp Wireless’ Ultra-Link Processing™ (ULP) eNode and its use within a ULP wireless packet data network. It also provides information about the hardware and software interfaces. It is intended for use by customers integrating the On-Ramp Wireless’ eNode module into their sensor and location tracking systems (referred to as hosts in this document). On-Ramp Wireless Confidential and Proprietary 1 010-0002-00 Rev.
2 Ultra-Link Processing Overview The Ultra-Link Processing ™ (ULP) wireless packet data network, comprised of eNodes and Access Points (APs) operates at a breakthrough receive-sensitivity of -142 dBm. This dramatic increase in receive sensitivity allows for a 2,000 mile wireless range in free space and 25x the range (600x the coverage) of typical wireless sensor systems while maintaining a small and lowcost form factor with multi-year battery operation.
3 Regulatory Approvals The eNode has been designed to meet regulations for world-wide use. 3.1 Federal Communications Commission This device complies with part 15 of the Federal Communications Commission (FCC) Rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference 2. This device must accept any interference received, including interference that may cause undesired operation.
eNode User Manual Regulatory Approvals To reduce potential radio interference to other users, the antenna type and its gain should be chosen so that the equivalent isotropically radiated power (EIRP) is not more than that permitted for successful communication. Canadian Two Part Warning Statement: This device complies with Industry Canada licence-exempt RSS standard(s).

4 eNode Interfaces The eNode platform provides ULP modem functionality on the client side. The eNode platform handles PHY and MAC layers (L1 and L2) for the ULP technology. The eNode platform supports interfacing over Serial Peripheral Interface (SPI). The eNode easily integrates with a sensor or location tracking system using the software and hardware interfaces supported. The eNode acts as the slave device and the host board acts as the master. 4.1 Hardware Interface 4.1.

eNode User Manual eNode Interfaces 4.2 Software Interface On-Ramp Wireless’ eNode platform’s Software Interface includes the node resident SPI driver for the Interface Hardware and the node resident messaging application. While the driver enables the hardware for data transfer, the messaging application implements user-level messages which enable the host to control the behavior of the node.

[Future releases] Collecting debug data from the eNode. [Future releases] The messages can be broadly classified as Debug, Configuration, and User Data messages. 4.3.
eNode User Manual eNode Interfaces high. A high level on MRQ will wake up a sleeping node and will prevent the node from going back to sleep. 4.3.5 Slave Request The node requests a message transfer from node-to-host by driving the SRQ high. Hosts that support bi-directional SPI traffic respond to SRQ by sending a message request to the node after the completion of any ongoing transfers. 4.3.6 Other Signals Other signals (i.e., MISO, MOSI, SCLK, SS) are as per SPI Standard. 4.3.
5 Software Upgrade Protocol 5.1 Overview The node supports upgrading of its software via the host SPI interface. This mechanism allows a host which has access to a new software image to transfer the image to an attached node in small pieces and have them written to flash. After the entire image has been transferred the node is powered cycled to boot the new software image. 5.2 Requirements The node must be in the idle state when a software upgrade is attempted.
