The Federal Communications Commission (FCC) issued a $7,000 forfeiture against Sennheiser Electronic Corporation for willful and repeated violation of Section 302(b) of the Communications Act of 1934; the apparent violation involves Sennheiser’s marketing of unauthorized radio frequency devices.

In July 2008, the Enforcement Bureau Spectrum Enforcement Division began an investigation into Sennheiser’s marketing of wireless microphones. In a letter of inquiry dated August 15, 2008, the Division instructed Sennheiser to provide specific information regarding the manufacture, marketing, and the certification status of the wireless microphone systems it sells. In its September 15, 2008, response to the letter of inquiry, Sennheiser indicates that, while preparing its response, it discovered that one of its wireless microphones did not have a valid certification.

Manufacturers of Information Technology Equipment (ITE) intended for sale in the European Union should take note of some important changes that are slated to go into effect with regard to their EMC testing requirements under emissions standard EN 55022:2006.

In November 2008 the European Union’s Official Journal (OJ) published lists of standards for the Electromagnetic Compatibility (EMC) Directive and Radio and Telecommunications Terminal Equipment Directive (R&TTED). Both lists include references to EN 55022:2006 and its amendment A1, released in 2007.

EN 55022:2006 will supersede EN 55022;1998 and become the requirement for Information Technology Equipment (ITE) sold into the European Union after October 1st 20091 , with the requirements of Amendment A1:2007 coming into force one year later on October 1st 2010. What are the differences between the 1998 and 2006 versions of the standard and what new requirements will be introduced by A1:2007? Let’s begin by reviewing the history of CISPR 22 from 1997 onwards. International Standard CISPR 22 is the basis for not only EN 55022 but also for many of the other national versions of standards for ITE.

National Technical Systems Inc (NTS) has begun ZigBee testing for RF4CE platforms. The new RF4CE test program will verify functionality and interoperability of the ZigBee RF4CE across multiple vendors, with product-level certification testing soon to follow. Testing of the specification will allow manufacturers to quickly and easily develop interoperable products based on the standard.

Culver City, CA (PRWEB) June 8, 2009 — National Technical Systems Inc. (Nasdaq:NTSC) (NTS), a leading provider of quality, conformance and certification testing, quality registration and managed services, announced today that it has kicked off its testing program for the ZigBee RF4CE specification.

The ZigBee RF4CE specification was designed for radio-frequency based remote controls, providing a low power solution that removes line-of-sight issues commonly associated with typical consumer remotes. NTS has been working with the ZigBee RF4CE Special Interest Group (SIG) for several months on a defined test standard that would allow for low-cost compliance verification of remote controls and “targets” (e.g., TVs, stereos, CD players, etc.). In addition, the standard allows for two-way communications (between remote and target, or even target to target) for a better consumer experience.

The RF4CE test program will verify functionality and interoperability of the ZigBee RF4CE platforms across multiple vendors, with product-level certification testing soon to follow. Testing of the specification will allow manufacturers to quickly and easily develop interoperable products based on the standard.

“NTS has been an authorized ZigBee test lab for many years, and we are pleased that we will be performing testing for the new consumer electronics standard for ZigBee members,” said Osman Sakr, NTS CTO. “ZigBee RF4CE will open up an entirely new market to the benefits of ZigBee technology, and we are looking forward to being part of the radio-frequency remote revolution.”

“Working with an experienced certification provider, like NTS, has allowed us to offer a meaningful, cost-effective certification program, so that ZigBee members can get ZigBee RF4CE products to market quickly,” said Bob Heile, Chairman of the ZigBee Alliance. “We look forward to continuing to work with NTS on ZigBee public profile certifications.”

“NTS has been a great contributor in the timely completion of the ZigBee RF4CE certification program,” commented Victor Berrios, chairman of the ZigBee RF4CE compliance working group. “Their experience in testing and input to the working group was a valuable resource when working on the program.”

ZigBee RF4CE: More flexibility and control

The ZigBee RF4CE specification is based on IEEE 802.15.4. MAC/PHY radio technology in the 2.4GHz unlicensed frequency band and enables worldwide operation, low power consumption and instantaneous response time. It allows omni-directional and reliable two-way wireless communication, frequency agility for enhanced co-existence with other 2.4GHz wireless technologies, simple security set-up and configuration. During the next quarter, the Alliance will develop a test program consistent with existing policies for specifications and public application profiles. Once complete, products using a public application profile based on the ZigBee RF4CE specification can be submitted to an authorized test house for certification.
