The Milli 5 leverages Silver Spring Networks proven, self-forming, self-healing networking capabilities to bring connectivity to a new class of IoT devices. The small form factor and power-optimized design brings secure, reliable two-way integrated IPv6 connectivity to critical infrastructure. Silver Spring Networks Technology Silver Spring Networks provides autonomous wireless communication to geographically distributed devices, utilizing onboard firmware to securely communicate and interoperate with compatible wireless nodes to form a wireless mesh network. Silver Spring employs frequency hopping techniques to hop through frequency channels in unlicensed spectrum available worldwide. Each node hops in a pseudo-random hopping sequence, meaning each node synchronizes with other nodes in order to communicate on the network. Silver Spring utilizes time-based synchronization based upon a common time propagated through the network as a resource. Upon boot-up, Silver Spring devices enter acquisition mode, where they scan the available frequencies for discovery beacons. The discovery beacon contains the information necessary to synchronize their frequency-hopping. A host is any device to which the communications module is connected. A host application is any application that runs on that host. Silver Spring Networks IPv6 mesh is designed to mitigate unnecessary traffic as much as possible to reduce the probability for interference, excessive noise floor, and other deleterious RF effects that typically occur when unnecessarily chatty protocols are usedthat is, those with excessive keep-alive, polling, and other messages being broadcast continually. Each node is capable of dynamically identifying alternate routes SPECIFICATIONS Radio and Networking Capabilities Operates in 870-875.6 and 902-

This leads to an extremely resilient network topology compared to other star topologies. The (logical) network topology of a battery mesh. The nodes in the diagram represent logical positions (not physical locations) in the battery mesh routing tree. How Milli 5 Battery Meshing Works In a battery-powered device, Milli 5 operates off the hosts power supply. To conserve power, Milli 5 spends most of its time sleeping. (Nodes sleep when not otherwise occupied with operations.) Milli 5 sleeps at about 1.4A or ~0.3 Joules/day. During installation, batterypowered devices (BPDs) perform an aggressive discovery of other BPDs or constantly powered devices (CPDs). Thereafter, BPD nodes wake up periodically and listen in a receive window. The energy required for receiving is approximately 3mJ/

second. Upon powerup, Milli 5 listens periodically for discovery packets from CPD/

BPD. These are used to establish time synchronization and establish the node on the network.

* Pins 316 are bidirectional, inputs are pull up/pull down, and outputs are configurable as pushpull or open drain. Drive capacity varies with pin. 50 ohm PCB Design Guidelines Antenna design and RF layout are critical in a wireless system that transmits and receives electromagnetic radiation in free space. The Milli 5 module does not include an antenna connector. The antenna (or unique antenna connector) must be connected to Milli 5 via a transmission line implemented on the host PCB. SSN recommends the use of a co-planer Waveguide to minimize space and board real estate. The PCB trace should be kept as short as possible to minimize path loss. IPC 6011 and IPC 6012 Class 2 or better PCB manufacturing practices must be followed to ensure repeatable results. The transmission line trace will be bounded on both sides by a ground reference plane. For EMI considerations this ground plane should be extended and connected to other ground layers, one of which is on the opposite side of the PCB. The opposite side ground plane shall be contiguous under the trace and shall extend beyond the trace. These ground planes should be stitched together using vias spaced 40-50 mils (2 mm) apart. Avoid breaking up these ground planes by routing traces through them. Avoid routing any other signal traces, especially high speed digital signals, near the transmission line. Locate the transmission line trace away from power supply lines and power supply regulatory circuitry. Key design parameters The antenna trace must have a characteristic impedance of 50 5%. The recommended dimensions and the Gerber layout for the antenna trace are provided on the following pages. To calculate the key parameters requires calculating transmission line parameters. Although there are many transmission line and trace impedance calculators found on-line, they are not as thorough as specialized tools, and in simplifying the calculations, may omit critical variables.

Labeling Requirements for Host Device The following is an extract from FCC PART 15 UNLICENSED MODULAR TRANSMITTER APPROVAL, DA 001407, Released: June 26, 2000, Section 6 describing labeling requirements for devices containing a modular transmitter. Section 6. The modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following:

Contains Transmitter Module FCC ID: XYZMODEL1 or Contains FCC ID: XYZMODEL1. Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. The following is an extract from RSS-GEN, General Requirements and Information for the Certification of Radio Apparatus, Section 3.2.1, describing labeling requirements for a host device integrating a radio module. The host device shall be properly labelled to identify the modules within the host device. The Industry Canada certification label of a module shall be clearly visible at all times when installed in the host device, otherwise the host device must be labelled to display the Industry Canada certification number of the module, preceded by the words Contains transmitter module, or the word Contains, or similar wording expressing the same meaning, as follows:

Milli 5 Radio Certifications Silver Spring Networks Milli 5 is integrated into application specific hosts which provide power regulation, buffered data inputs, and 50 ohm transmission line to antenna or external antenna connector. The following table describes the hosts that support Milli 5 FCC/IC Certification. SSN P/N 174-0768-00 Description Hardware Development Kit

(HDK) Antenna External SMA 170-0818-00 Logistics NIC (LNIC) On-board SSNI 420-0319-00 170-0845-00 Milli Arduino Shield Board External SMA OEM Certifications Silver Spring Networks Milli 5 is FCC/IC Certified as Limited Modular Approval (LMA). LMA may be granted to a device which cannot meet all the requirements of a Single Modular Transmitter and if compliance can be demonstrated under the operating conditions in which the device will be used. OEMs have the following options for FCC/IC Certification using an LMA:

Option 1: Use current FCC/IC Grant, without need of an additional Certification by following these rules:

Design to the strict guidelines for layout as described in 50 ohm PCB Design Guidelines, Use an external antenna of same type as tested (JPole OmniDirectional) with equal or less gain, Deliver power regulation to Milli 5 as described in Recommended Operating Conditions, Deliver buffered modulation/data inputs to Milli 5 Label the host device with, Contains FCC ID: OWSMIL51 and Contains IC:

5975A-MIL51. Option 2: If all rules from Option 1 are used, but a different type of antenna is required for the application, request a Change in ID application to reuse data from the current FCC/IC Grant, then apply for a Class 2 Permissive Change to add the antenna. The integration would require some additional conformity against CFR 47 Parts 15.203, 15.209, and RF exposure to add antenna to the Certification. Contact Silver Spring Networks for authorization to apply for a Class II Permissive Change. Option 3: Integration will need to pursue own full FCC Certification if design does not follow strict guidelines for layout. OEM may choose to obtain own FCC Certification even if guidelines are followed. Collocation: If other wireless technologies are operational at the same time, then certification testing may be required for each technology, including evaluations of simultaneous transmissions from independent transmitters.
