Workshop Information:
FCC Part 15.407 DFS and TPC Requirements:
The FCC has issued final ruling on Dynamic Frequency Selection (DFS)
and Transmitter Power Control (TPC). This issue has officially been
postponed until January 20, 2006. The announcement was made February
23th, 2005 at the TCB workshop in Turf Valley, Ellicott, MD.

Hearing Aid Compatibility Update:
ANSI standard C63.19, Version 2001 is still in effect until the FCC
approves use of the revision, which was to be voted upon in February
of 2005 during the re-balloting phase. No Hearing Aid Compatibility
(HAC) applications have been submitted to date. Additionally, the
following are in development:
(a) Test capability for all C63.19 testing
(b) Appropriate TCB procedures to be developed, but no timeframe is
yet in mind Back to Top
Part 80 EPIRBs and Part 87 ELTs:
TCBs can now approve Part 80 121.5/406 MHz Class C (Emergency
Position Indicating Radio Beacons) EPIRBs, Part 80 Ship Security
Alert Systems (SSAS) and Part 87 Emergency Location Transmitters (ELTs).
The EPIRBs and SSAS approvals will require approval letters from the
US Coast Guard, while the ELTs will require approval letters from
the Federal Aviation Administration (FAA). Also, according to a
presenter at the FCC Workshop, beginning in 2009, only 406 MHz
beacons will be detected by the Cospas-Sarsat satellite system.

Vehicle Directive 2004/104/EC:
When the new Vehicle Directive 2004/104/EC is compared to the
current Vehicle Directive 95/54/EC, the following are found:
(a) Emissions are the same as before;
(b) There is more stringent Immunity testing in the new Directive;
(c) The new Directive covers equipment related to safety functions.
Products unrelated to safety functions should meet either the EMC or
R&TTE Directive, as appropriate.
(d) As of July 1, 2006 “Electrical Sub Assemblies (ESAs) that do not
meet Annexes I to X of the Directive, shall no longer be granted EC
type approval and may be refused national type approval. (This
information was presented in February 2005 at the FCC’s TCB
Workshop). Back to Top
EMC Directive 2004/108/EC:
The new EMC Directive 2004/108/EC supersedes the current EMC
Directive 89/336/EEC on July 20th, 2007, it cannot be used before
July 20th, 2007. Furthermore, the current Directive 89/336/EEC
cannot be used after July 20th, 2009. This Directive does not cover
“R&TTE Equipment, Aeronautical products, parts and compliances, and
equipment that will not produce levels above permitted limits and
will operate without unacceptable degradation in the presence of
expected electromagnetic fields. Guidelines will be published around
December 2005 (This information was presented in February 2005 at
the FCC’s TCB Workshop).

Test Report: All Test reports submitted
to the FCC to support compliance of a device should incorporate the
requirements of ISO/IEC17025, ANSI C63.4-2003, and the FCC Rules and
Regulations. Back to Top
Questions and Answers:
Approval of 15C Booster/Antenna Port:
Q: We would like to approve our Access Point (AP) and Booster device
as a system with one FCC ID. Is this possible?
A: An AP and Booster device can be approved as a booster or as a
system. When approved as a system, the label should be located on
the host (AP). The label may state that it is for use with a
specific system (the Commission prefers that labeling not be placed
on booster). If on the other hand the Booster is approved separately
(but is still for use with your specific system), the Booster should
be labeled with an FCC ID.
Permissive Changes & Antennas:
Q: We have a new antenna that is the same type as the
original; furthermore, there are no changes to our device. When is a
Class II, Class I Permissive Change or new FCC ID required?
A1: Class II Permissive Change: The following are
scenarios that require a Class II permissive change filing when
a new antenna is added:
(a) When the antenna gain of the new antenna of the same
type as the originally approved antenna is greater than the
antenna gain of the originally tested antenna
(b) When the emission levels or reported RF safety levels of
the same antenna type increases
(c) If the antenna is a different type, has a lower gain
than the originally approved antenna and tests show that the
spurious emission levels or reported RF safety levels have
increased
A2: Class I Permissive Change: A Class I Permissive
Change filing may be done for the following scenarios:
(d) When the new antenna is of the same type, same
specifications, and has the same or lower gain than the
antenna(s) originally approved, and new tests show that the
emission levels or reported RF safety levels are not
increased
(e) When the antenna is a different type, has a lower gain
than an originally approved antenna and tests show that the
spurious emission levels or reported RF safety levels are
not increased, then a Class I Permissive change is
permitted. Although a Class II Permissive Change filing is
not required in this case, it is recommended that a Class II
Permissive change be filed in order to keep a complete list
of approved antenna(s) in the filing
(f) When the specifications and gain are the same as an
antenna originally approved but is made by a different
manufacturer
A3: New FCC ID: Depending on your specific hardware or
software change(s), a new filing may be required.
EMC and SAR for Class II Permissive Change:
Q: We are doing a Class II permissive change for our device,
which was originally tested for SAR compliance. Should EMC and SAR
testing for the Class II permissive change be done at the originally
rated and granted power?
A: Yes.
Q: Can Specific Absorption Rate (SAR) testing be done at a
higher power than the EMC test (at nominal power)?
A: No. In this scenario, a new FCC ID with EMC and SAR both
at higher power may need to be considered. Or, a filing with the FCC
directly, with limited SAR testing (after conferring with FCC) to
prove linearity may be an option.
Confidentiality Request:
Q: When I submit my documentation for approval, is it
necessary to cite the specific FCC rule section in the
confidentiality request letter?
A: Yes, it should be apparent in the letter that the request
for confidential treatment is being made under the provision of 47
CFR 0.459.
Satellite System Frequency Translator – 15.247 vs. 15.249:
Q: We are beginning the testing process for our frequency
translator. I am aware that there was a recent FCC interpretation on
frequency translators (does not demodulate). Does this
interpretation apply only to 15.249?
A: Yes, this recent interpretation specifically prohibits
15.247 operation for frequency translators due to the higher power
limits and the increased potential for harmful interference. This
interpretation specifically covers operation under 15.249, only.

In an effort to begin
addressing the growing demand for two-way broadband data and
communications capabilities onboard aircraft, the Federal
Communications Commission has issued a Proposed Rulemaking
addressing a regulatory framework for licensing the operation of
Aeronautical Mobile Satellite Service (AMSS) systems to communicate
with fixed-satellite service (FSS) networks in the Ku-band
frequencies was presented.
NOTICE OF PROPOSED RULEMAKING RELEASED
FEBRUARY 16, 2005 – PROPOSED AMENDMENTS TO PART 90 ARE GEARED TO
MORE FLEXIBLE USE OF CHANNELS IN B/ILT POOLS (896-901/935-940MHZ).
(See FCC No. 05-31)
UNLICENSED NATIONAL
INFORMATION INFRASTRUCTURE (U-NII) DEVICES IN THE 5 GHZ BAND
(See FCC No. 05-43)
On February 23, 2005,
the transition periods adopted in the 5 GHz U-NII Report and Order
have been extended for one year. This action will allow unlicensed
National Information Infrastructure (U-NII) equipment operating in
the 5.250 – 5.350 GHz band to continue to obtain equipment
authorizations. Until measurement procedures for evaluating such
devices for compliance with the new rules are developed, the devices
will be marketed under the rules in effect prior to the adoption of
the 5GHz U-II Report and Order. Back

IC:
Industry Canada has issued a
Temporary Moratorium of Phase 2 Radio Equipment Certification and
Licensing Requirements
-
Redeployment Plan (100-500 MHz)
See
Notice
No. SMSE-001-05 -
A temporary moratorium has been issued for the January 1, 2005
proposed implementation date of Phase 2 radio equipment
certification and licensing requirements currently required under
the Redeployment Plan for Spectrum Efficient Land Mobile
Equipment in the Frequency Range 100-500 MHz. The Department
will be taking into consideration the emerging narrow band radio
equipment market and any required near term consequential decisions
before discontinuing this moratorium and directing a new
implementation date. See the Notice for further information
regarding new systems licensed after January 1, 2005 and transition
information. Back
