FCC Part 15 Certification

Gentlemen,

Pursuant to 47 CFR 0.457(d)(1)(ii) and 0.459 Silver Spring Networks hereby requests permanent
confidentiality of the following documents for the subject application:

Exhibit Type                    File Name                                           Description

Operational Description         OWS-IMU521_Functional Description.pdf               Operational Description
Internal Photos                 OWS-IMU521 – Internal Photos.pdf                    Internal Photos
Schematics                      OWS-IMU521 Schematic.pdf                            Schematics
User Manual                     IMU300_GasIMU300_Install.pdf                        User Manual

These documents contain detailed system, equipment description, and related information about the product
which Silver Spring Networks considers proprietary, confidential, and a custom design not otherwise
available to the general public.

Since the design is a basis from which future products will evolve, Silver Spring Networks considers that this
information would be of significant benefit to its competitors and that disclosure would give competitors an
unfair advantage in the marketplace.

Justification for keeping internal photographs and user manual confidential

This product is not sold to the general public; it is sold only to electric and gas utilities. There are no
serviceable parts except for the battery which is designed for a 20 year life before replacement. In addition,
the circuits under the shields are filled with waterproof potting material.


Sincerely,




                            Name:      Asim Tirmizi
                          Company:     Silver Spring Networks
                              Title:   Senior Regulatory Compliance Lead
                             Date:     4/30/2014
