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 (WLANs), which were adopted in their
recent Report and Order on this subject. 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).
The FCC is also denying a request by Globespan Virata to revise
the rules to state that U-NII devices are not required to detect and
avoid frequency hopping radar signals, and also dismissing a request
by Extreme Networks Inc. to modify the definition of a U-NII central
controller that must include Dynamic Frequency Selection (DFS)
capability. The FCC also issued a revised measurement procedure for
certifying U-NII devices for compliance with the DFS requirements in
these bands. The FCC says that these actions are intended to ensure
that all applications for equipment certification of U-NII devices
filed on or after July 20, 2006 will comply with all U-NII
requirements for these bands. In essence, this makes the DFS
requirements official for new products effective immediately and will
become a formal requirement for products already on the market by
July 2007.

Lighting Manufacturer to Pay $700k for Hazardous Lights
The U.S. Consumer Product Safety Commission (CPSC) has reached an
agreement with Acuity Brands, Inc. of Atlanta, GA, under which the
company will pay a $700,000 civil penalty for failing to report
defects and hazards associated with more than 1.4 million of its
Lithonia Lighting products.
The CPSC conducted four separate investigations into the timing
of Acuity's notification to the agency of defects with its lighting
products. The company allegedly received hundreds of reports of
product failures, including fire and smoke hazards, cracked and/or
falling reflector lenses, defective cords, and at least two reports
of injuries. However, in each instance, the company redesigned and/or
replaced the defective lighting fixtures prior to notifying the CPSC
of the product defects.
Federal law requires manufacturers, retailers and distributors to
report to the CPCS immediately upon receipt of any information that
would support the conclusion that a product contains a defect which
presents a substantial or unreasonable risk of injury or death to
consumers. However, in agreeing to settle the matter with the CPCS,
Acuity did not admit the CPSC's allegations and denied that it
violated any law. Our readers can learn more about the CPSC's action
against Acuity at
