Providing information and fielding
questions for wireless manufacturers are some of the many activities
that we perform at ATCB. Packets provides an overview of just a
small portion of the communiqués that run in and out of our office.
Questions and
Answers:
FCC:
Q: I have a BT headset - obviously a small device. Because BT
headsets are so small, are they required to have at least the FCC ID
on the device?
A: The device must
have the FCC ID on it regardless of size.
Q: We desire to certify a cellular repeater
(Part 22). It has two separate amplifiers for uplink and downlink,
and amplifies on air signals in the cellular band. The device does
not demodulate or re-modulate an incoming signal. It is
fundamentally a bi-directional amplifier (signal booster) although
it is constructed around the heterodyne principal. The unit
comprises of saw filters and cavity filters for the 824-849 and
869-894 bands only. The incoming signals are only down converted to
an IF level frequency of 70 MHz and band width limited to 25 MHz by
a SAW filter. Note, no alteration to the signal occurs anywhere in
the system. This product is intended to be sold and marketed to only
CDMA licensees only. However there is nothing at the input to limit
other technologies from being amplified and it is a multi-channel
amp. For this device, is it necessary to test or list with other
signals which it may be subjected to (GSM/TDMA, etc)?
A: If the device
is intended and marketed only for the CDMA providers, then only the
CDMA modulation needs to be tested back to

IC:
Q: If the model number is also the UPN portion of the Certification
Number, does IC consider this to be sufficient to cover the model
name/number requirement?
A: The label must contain the following information:
(a) the
certification number, prefixed by the term “IC:”;
(b) the manufacturer's name, trade name or brand name, and
(c) a model name or number.
You can have many
different models under the same UPN. It becomes difficult to
identify a particular model when families of models are approved
under the same UPN if the model name is not on the label. It is
acceptable to have a label without the model name on it, if the
model name is printed somewhere else (e.g. on top or front of the
product) and is visible. back to

Designating Accrediting Authority Daily Updates; Federal
Communications
Commission (FCC), Industry Canada (IC), and Compliance Europe (CE)
FCC:
The
Telecommunications Certification Body Council (TCBC) announced the
2006 Fall Workshop on October 2nd through 4th at the Sheraton Inner
Harbor Hotel in Baltimore, Maryland. Topics will include: FCC/IC/IDA
updates; TCB Code of Practice; How to audit a non-accredited test
lab; DFS: The differences between FCC and DRAFT EN 301 893; RF
Exposure for 802.11 & 3G technologies; FCC Roundtable discussions;
plus an industry update on an emerging technology. Visit
www.tcbcouncil.org for more information.
The FCC recently issued a Memorandum Opinion and Order (MO&O),
August 7, 2006 in the matter of ET Docket No. 04-37 - Amendment of
Part 15 regarding new requirements and measurement guidelines for
Access Broadband over Power Line Systems and ET Docket No. 03-104
Carrier Current Systems, including Broadband over Power Line Systems
in response to various petitions for reconsideration of the Report
and Order. The FCC is further amending Part 15 of the rules
regarding the unlicensed operation of Access broadband over power
line (BPL) systems.1 Specifically, they are amending the rules to
eliminate the exclusion zone requirement for the ten listed radio
astronomy facilities and to add a new exclusion zone for one Very
Large Array (VLA) radio astronomy observatory site at 73.0-74.6 MHz.
In addition, the FCC is amending the rules to add prospective
protection for relocated aeronautical facilities and to correct the
coordinates and email contact for the aeronautical facilities
subject to BPL consultation. back to

FCC Makes DFS Requirements Official
The FCC recently issued a Memorandum Opinion and Order (MO&O),
responding to requests for clarification or reconsideration of the
new rules for Unlicensed National Information Infrastructure (U-NII)
devices in the 5.25-5.35 GHz and 5.47-5.725 GHz bands, including
Wireless Local Area Networks (WLAN’s). Specifically, the FCC is
granting a request by the Wi-Fi Alliance to clarify the Transmit
Power Control (TPC) requirements in section 15.407(h)(1), but
dismissing a request by the Wi-Fi Alliance to clarify the channel
availability check time requirement in section 15.407(h)(2)(ii).

New Interpretation for Part 90.210 L and M masks for 90Y
With regard to the
L and M masks in Part 90.210, the rule indicates using a minimum RBW
of 1% of the fundamental emission to determine the reference level
and a minimum RBW of 1% of the fundamental to determine the mask
skirts. The mask should be developed using the same resolution
bandwidth throughout, for the reference level and the mask skirts.
This interpretation was coordinated with the Wireless Bureau and the
inquirer was asked whether the same RBW should be used or could
different RBW be used so long as each was greater than 1% of the
fundamental.
Section 90.210(l)
states that "...the power spectral density of the emissions must be
attenuated..." This is different than other masks since it is the
power spectral density measured, instead of the maximum average
power for the emissions measurements. Therefore, the zero dB
reference must be compatible with power spectral density in order to
directly compare to the emission level. For this reason the zero dB
reference level is measured with a >1 percent RBW, but not
integrated to full bandwidth power in order to give the power
spectral density level of the carrier. The emissions are measured
with the same RBW to yield power spectral density levels and then
compare with the zero dB reference which is the carrier power
spectral density level. back to
