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.
Questions and Answers:
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 top...
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 top...

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 top...
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 top...
