Anche per il mercato USA Nord-Americano e Canadese è necessario verificare la compatibilità elettromagnetica (EMC) dei dispositivi di telecomunicazione radio. Le prove e le certificazioni FCC e ISED deve essere condotta presso un Telecommunications Certification Body (TCB).
Come nel mercato Europeo, anche in USA e Canada l’utilizzo dei dispositivi che operano come trasmettitori intenzionali e non, viene regolamentato al fine di evitare interferenze con altre apparecchiature elettroniche o con telecomunicazioni radio. Nemko è in grado di seguirti in tutti gli step del tuo progetto FCC (Federal Communications Commission) e ISED (Innovation, Science and Economic Developmen , nuovo IC – Industry Canada); dalla prima fase prototipale alla certificazione completa.

• The US Federal Communications Commission has recently amended the
rules governing the authorization of radio frequency equipment.
Amongst other, the rule changes mean that two authorization procedures,
Declaration of Conformity (DoC) and Verification, have been combined
into one procedure called Supplier’s Declaration of Conformity (SDoC).
There was previously some confusion for many devices whether fitting into
the Verification or DoC category. Combining these categories simplifies the
authorization process for products that are not subject to Certification.
One significant change is that test results from an accredited test laboratory is
no longer a must. The SDoC process includes the requirement for a
compliance statement in the product documentation that identifies for
consumers who is responsible for the compliance of the device. The
responsible party must be located in the United States.
The FCC logo currently used for the DoC process is no longer required, but
the FCC will allow manufacturers to continue using the logo at their option.
Amended US rules for RF equipment
16. 02.12.2016 NEMKO ITALY CUSTOMER SEMINAR16
The responsible party, typically the manufacturer, obtains an FCC Registration
Number (FRN) for a device requiring Certification. The FRN is a 10-digit number
used to identify the individual or organization doing business with the FCC. The
same FRN will be used for future approvals.
After obtaining an FRN, the responsible party obtains a Grantee Code from the
Commission by applying at the Grantee Registration website. A grantee code is
required the first time a party applies for certification, and can be used for all future
approvals.
The responsible party files with a Telecommunication Certification Body (TCB) an
application for a grant of certification. An application for equipment authorization
requires submission of information about the product, as listed in Section 2.1033.
The applicant must submit the required information to a TCB for review as part of
the certification process.
The TCB assess all of the information and evaluation results to determine if the
product complies with the FCC requirements.
Once the TCB makes a decision to certify the product the supporting information is
uploaded to the FCC Equipment Authorization Electronic Filing System (EAS)
A grant of certification is issued by the TCB on the FCC EAS.

19. • The FCC ID consists of two elements, a grantee code and an equipment
product code. The FCC ID is assigned for Equipment Authorization under
various Title 47 rules including but not limited to Parts 15, 90, and 101.
• The Grantee code is a three character alphanumeric string representing the
Grantee/Applicant. The Grantee Code always begins with an alphabetic
character and does not contain the numbers one and/or zero. The Grantee
Code is assigned by the Commission permanently to a company for
authorization of all radio frequency equipment.
• The Product Code is the non-grantee code portion of the FCC ID that begins
after the first three characters. The Product Code may include hyphens and/or
dashes (-).

Multiple Authorization Procedures
• A device subject to multiple authorization
procedures requires appropriate testing
and labelling for each of the respective
authorization procedures. As a general rule,
the DoC text statement supersedes any
Verification statement. For devices subject
to DoC and Verification, or Certification and
Verification, the labelling requirements for
DoC or Certification need only apply. When
a device is authorized under both the DoC
and Certification procedures, the DoC logo
and FCC ID (or FCC IDs if applicable) are
required.

Certified Transmitter Modules
• Certified transmitter modules (CTM) are distinctive assemblies
containing a transmitter that can be installed inside a host device (i.e.
computer, wireless security controller, etc.).
• When a certified modular is used inside a host, the host equipment
can take advantage of the certification already granted to the module.
The host containing a certified modular (for example a laptop with
WiFi) may only require testing for DoC or Certification as a Class B
computer, and possibly a subset of additional tests associated with
the transmitter.
• Any additional testing, conditions of use and limitations associated
with the certified module must be provided in the module instruction
manual by the manufacturer of the module, to the Other Equipment
Manufacturer (OEM) marketing the host.
• A certified modular has the option to use a permanently affixed label,
or an electronic label. All modules without an integrated display on the
module must be labelled with a module’s FCC ID - Section 2.926.
26. 27.09.2017 WORKSHOP UN MONDO SENZA FILI: RED & FCC26
Modular Approval
• Single-modular transmitter: A complete RF transmission sub-
assembly, designed to be incorporated into another device, that must
demonstrate compliance with FCC rules and policies independent of
any host;
• Limited single-modular transmitter: A single-modular transmitter
that complies with the § 15.212 modular rules, only when constrained
to specific operating host(s) and/or associated grants condition(s);
• Split-modular transmitter: An RF transmission system that complies
with the requirements for a single modular transmitter, that is
separated into a radio front-end section and a control-element section,
and can demonstrate compliance for a range of similar type hosts;
• Limited split-modular transmitter: A split-modular transmitter that
complies with the definition and technical rules for split modules only
when constrained to specific operating host(s), and/or associated
grant condition(s).
27. 27.09.2017 WORKSHOP UN MONDO SENZA FILI: RED & FCC27
Permissive Change
• Changes from a non-modular to modular certification, and
from a full modular to a limited modular certification, are
permitted if the changes meet the requirements for a
permissive change in § 2.1043.
• The original grantee may submit new test data to modify
the existing limitations of the grant as permitted under the
permissive change rules (§ 2.1043). Evaluation
requirements include:
• a) All transmitters must have the required simultaneous
transmission test data;
• b) Simultaneous transmission evaluation requirements for RF
exposure.
