NTS Authorized To Perform USB 3.0 (SuperSpeed) Certification

NTS is pleased to announce that we have been authorized by the USB Implementers Forum (USB-IF) to conduct USB 3.0 SuperSpeed certification tests on SuperSpeed peripherals, SuperSpeed hosts (using certified silicon), and SuperSpeed peripheral building blocks.  USB 3.0 SuperSpeed is the latest version of the most popular device communication standard on computer, keyboards, mice, printers, hard drives, and a host of devices. For more information on how to get your USB 3.0 SuperSpeed device certified TODAY, please contact us.

NTS Begins Testing for ZigBee RF4CE Specification

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.

802.15.4 Compliance for ZigBee Certification

ZigBee Board

If you’re looking to get any platform, product, etc. ZigBee certified, you probably know that you need to check for 802.15.4 compliance before you move on to the higher layers. However did you know that ZigBee does not mandate the implementation of the full 802.15.4 MAC layer? Some functions of the 802.15.4 MAC are actually even prohibited in ZigBee and their use will cause your platform to be non-compliant. This not only reduces the testing you have to do, but also reduces code size and complexity that is not needed for your stack. Features such as GTS, MAC security, beacon networking, and PAN ID conflict on the MAC layer are just thrown out. In other words, ZigBee will only ask that you test a relatively small portion of the 802.15.4 MAC which should come as good news to all of you out there worrying about fitting all of this code in small memory chips to cut cost!
