Providing information and fielding
questions for wireless manufacturers are some of the many activities
that we perform at ACB. Packets provides an overview of just a
small portion of the communiqués that run in and out of our office.

series, EspressoEngineering.tv. This new series
provides education and explanation of
fundamental and fine engineering topics, aimed
at the test laboratory and compliance market.
Presented in short, focused segments,
EspressoEngineering examines current events and
engineering topics in our community in about the

Workshop On Mutual Recognition Agreements For
Conformity Assessment Of EMC And
On May 5-7,
2009, the National Institute of Standards and
Technology (NIST) and the U.S Federal
Communications Commission (FCC) will co-host the
Second International Workshop on Mutual
Recognition Agreements for Conformity Assessment
of EMC and Telecommunications Regulations at
NIST in Gaithersburg, Maryland. Click Here for
This is a
can’t-miss opportunity for Test Labs, Certification
Bodies and parties involved in International Product
Questions and Answers:
We have a tire pressure monitor operating at 433MHz. The
receiver is powered from 12VDC (DC to DC). What standard must we
follow? FCC part 15 B or SAE? If Part 15B is power line
conducted emissions testing required?
ANSWER: The intentional radiator portion of this device
must comply 15C. This device, specifically, must comply with
15.231. For all receivers associated with this device, only 15B
will apply for unintentional emitters. No power line conducted
emissions are required for battery-operated equipment.
If this device is a “super-regenerative receiver”, it must be
‘keyed” with a radiated signal at its receive frequency to
maximize emissions. Please see ANSI C63.4 for further details.
(“SAE” is the Society of Automotive Engineers, a
standards-making body in the United States. The regulatory
requirements for this type of device fall under the FCC. The SAE
does not regulate RF transmitters per se. It may have other
requirements, however, that are industry-specific and are
generally called out by the specific automobile manufacturer.)
QUESTION: Was EN50361 replaced by
EN62209-1 recently? If so how about EN50360?
ANSWER: Presently, there
is a SAR standard for mobile phones, it is EN 50360. (Also, EN
EN 50360 is the harmonised
standard for performing the tests on phones.
However, there are no harmonised standards for SAR on any other
device: WLAN dongle, WiMAX dongle, Walkie-talkie, etc. At this
time, manufacturers of these devices need to decide on a set of
tests to which to claim compliance. They may also request a
Notified Body to advise on a test suite to use and possibly give
an opinion on the TCF.
There are new standards under development: EN 62209-1 and EN
62209-2. These are generic SAR standards for Head devices and
Body devices. They are intended to cover SAR tests on many types
When published and harmonized,
it is expected that they may replace EN 50360.
EN 62209 is not yet harmonized. This means that the manufacture
should continue following any existing harmonized standard.
If they decide to use EN 62209, then they should obtain a
Notified Body opinion.
QUESTION: I understand that TCBs CANNOT
review Part 90 subpart Z in the 3650 – 3700MHz band (it may be
the application for 3.5G WiMAX in FCC). Is it correct? Or is Certification under
“Permit But Ask” the necessary route for approval?
ANSWER: Part 90 applies and, because this device operates
on contention based protocol, it must be Certified by the FCC.
QUESTION: Please help to clarify the “Canadian
1. Does IC require a physical
Canadian to answer the phone from IC?
2. Can the Canadian rep be
located in the U.S or Japan to answer the phone which has been
transferred from his office in Canada?
ANSWER: A company located outside Canada who applies for
certification must provide a Canadian representative with a
Canadian address and a Canadian telephone number. The Canadian
representative must be able to answer telephone calls from
Industry Canada during normal business hours within the Canadian
time zones. The Canadian Representative is also responsible to
provide on request, audit samples free of charges to Industry
Canada (no shipping charges or custom duty charges) and Industry
Canada must be able to ship back the audit samples free of
charges to a Canadian address.
Therefore, to answer your question, if the person or company
acting as the Canadian representative is providing a Canadian
address and telephone number and can meet all conditions listed
above but is, in reality, located outside Canada, this would
still satisfy our requirements and would be acceptable to
