Regulatory Certification Note 4 RZEMFIAN-007-20140121

1. Introduction

ReZolt provides embedded Wi-Fi (Em-FiTM) moduleRZ226MS, to enable low-power Wi-Fi

communication on deeply embedded devices. The ReZolt Em-Fi modules transmit and receive

radio signals in accordance with the spectrum regulations for the 2.4 Ghz unlicensed ISM band.

Regional regulatory agency approval may be required to operate these modules throughout the

world.

This document describes regulatory certifications applicable to ReZolt Em-Fi modules, as well

as regulatory certification requirements on end-products that integrate these modules.

1.1. Intended Audience and Reading Suggestions

This document is intended for customers of ReZolt Em-Fi modules.

1.2. Scope of the Document

This document provides general information involved with Regulatory Certification when

installing and operating ReZolt Em-Fi modules.

2. Module Description

ReZolt provides several Embedded Wi-Fi modules, including RZ226MS. The chart below

describes the block diagram of the two modules.

RZ226MS Module mainly consists of Broadcom BCM43362 Wi-Fi device, a 26 MHz crystal, and

an on-board chip antenna and a u.FL connector for optional external antenna.

3. Eligibility Requirements on Regulatory Certification

Most countries have a regulatory body for radio products and the wireless emissions that they

create. Generally, these bodies oversee three major areas for any radio device.

 Intentional radiation: This is the actual radio signal that is being generated and

transmitted by the device (i.e. ReZolt Em-Fi module). There are typically regulations for

radio communication radiating at frequencies or power outputs. The device in question

cannot radiate outside of predefined ranges and regulatory limits.

 Unintentional radiation: All systems radiate some energy as a result of onboard clocks

oscillators and other devices. If the unintentional radiation is strong enough, it can

interfere with normal operation of with other products that are close by, such as the

intentional radiator within the system (i.e. ReZolt Em-Fi module). Regulatory bodies

generally have specific limits that are set on unintentional radiation.

 Safety: Safety certifications ensure that the product has met regulatory specifications for

health, safety, and environmental requirements.

To help customers integrating Em-Fi modules with shorter time-to-market, ReZolt submit its

Em-Fi modules to relevant agencies and obtained regulatory approvals for specific countries,

under the “Modular Approval (MA) Grant”.

In countries that accept the MA Grant, the intentional radiation portion of this grant is

transferable to end-product manufacturers given adherence to specific implementation criteria

noted in this document. Such countries include US, Canada, and many European countries. This

means the end-product manufacturers are relieved from having to perform the radio

certification part in such countries. Detailed terms and conditions of regulatory approval for

these countries are described in this document.

However, any modification of the modules will void the manufacturer’s warranty. Any alteration

or deviation from the documented installation and/or operation of the modules will void the MA

Grant as it applies to the end-products. In such cases, the end-products may require a complete

regulatory certification, depending on the governmental requirements of the regions where the

products are sold.

The unintentional radiation (or digital emission) portion of the grant is not transferrable to end-

products in any cases.

4. Users Manual Requirements

For electronic devices that integrate ReZolt Em-Fi modules, their manufacturer must include

certain text in their product user’s guide, in accompaniment with other regulatory information.

The text may be disbursed according to language or geographic regions, if needed, but the exact

text shown below must be maintained.

4.1 United States Requirements

The users manual or instruction manual for an intentional or unintentional radiator shall

caution the user that changes or modifications not expressly approved by the party responsible

for compliance could void the user's authority to operate the equipment. This typically is

written as follows:

Caution: Changes or modifications not expressly approved by the party

responsible for compliance could void the user’s authority to operate the

equipment.”

Regulatory Certification Note 8 RZEMFIAN-007-20140121

5. United States Regulatory Approval

The requirements for United States FCC Modular Approval (MA) were released in June 2000 in

the FCC’s public notice: FCC Public Notice DA 00-1407, part 15 Unlicensed Modular

Transmitter Approvals.

5.1 Design Requirements

The following conditions must be strictly adhered to for MA:

1. No modification to the module including the circuitry is permitted

2. The design criteria including antenna, interconnects and transmission line

3. Testing of the final device configuration for Digital Emissions Compliance

The modules may not be altered or modified in any way by the OEM or other integrator(s).

Additionally, no component(s) may be added which change the radio frequency (RF)

characteristics. These include unintentional or spurious emissions, immunity, ESD

characteristics, or other items commonly associated with RF devices. This includes all

components; passive and active (such as RF filters and RF switches). Additionally, no RF

components may be placed between the RF output of the module and the antenna.

ReZolt Em-Fi modules consist of an on-module antenna which has been qualified and approved

for use under the MA certification. This antenna is designed to be compatible with the RF

impedance and frequency range of the modules. Any changes or modifications on the on-module

antenna voids the MA grant.

ReZolt Em-Fi modules also consist of a u.FL connector that can be used to connect an external

antenna to the module. Use of an external antenna voids the MA grant.

5.2 Unintentional Radiation Testing

Any end-products integrating ReZolt Em-Fi modules must meet unintentional radiation

compliance: FCC Part 15 Section 15.109 Sub-paragraph A, Class B Radiated Emission Limits.

The products must be tested in accordance with the above requirements in order to confirm

radiated emissions are within specified limits.

5.3 Co-Location of Additional Transmitters

For end-products using two or more co-located RF transmitters, please refer to the following

statement in the MA grant:

“This modular transmitter is approved for use in Digital Electronic Devices and may operate

in conjunction with other mobile and portable transmitters in the same device; provided, the

other mobile and portable transmitters have satisfied the appropriate RF exposure

requirements contained in the FCC rules. The grantee must also provide Digital Electronic

Device integrators, or end users if marketed directly to end users, with installation and

operating instructions for satisfying RF exposure requirements. The Grantee must inform

ReZolt RZ226MS Module

Regulatory Certification Note 9 RZEMFIAN-007-20140121

second manufacturers/installers that in order for this module to be operated in any

configuration other than that permitted in the preceding sentences, a separate FCC equipment

authorization must be obtained for each device into which this module is installed.”

5.4 Product Labeling Requirements

ReZolt Em-Fi modules are properly labeled with Regulatory Certification information, including

FCC ID. The FCC ID shown on the final product must be readily visible at the time of purchase.

If the module is installed in a location whereby the included label is visible, then a permanent

label with the statement below needs to be placed on the final product and no further labeling

need apply. If the product is to be labeled using electronic labeling. The end product users

manual must show the ID and provide user instructions on how to access the ID in software. If

the label is not visible after being integrated into the customer products, a permanent label

referring to the ReZolt module must be used on the customer products that refer to the FCC ID

listed below in form of “Contains Transmitter Module FCC ID: O2R-226MS”or

“Contains FCC ID: O2R-226MS”and including the statement shown below:

This device complies with Part 15 of the FCC Rules. Operation is subject to

the following two conditions: (1) this device may not cause harmful

interference, and (2) this device must accept any interference received,

including interference that may cause undesired operation.

Note if the product is too small (defined by <4 x 4 inches) or if approved by the FCC, this

statement may be placed in the manual.
