DFS Testing and Certification Services

Dynamic frequency selection is a technology that is designed to ensure that wireless devices operating in the unlicensed WLAN 5 GHz bands are able to detect when they may be interfering with military and weather radar systems and automatically switch over to another frequency where they will not cause any disturbance. These formal requirements are in effect in the USA, Canada, Europe, Japan, Australia, Korea and other markets around the world.

Over the Air Antenna Testing

National Technical Systems

During research and product development of any Internet of Things (IoT) device or Machine to Machine (M2M) product, it is important to make sure the antennas designed or selected will perform the way they are intended. For example, when designing an antenna for a large stationary device like a vending machine, it is likely installed or placed against a wall. Designing or selecting an antenna that concentrates its energy and radiates toward the front of the device would be ideal for this environment. In the case of a mobile device, like a smart phone, it is important for the antenna to radiate in all directions and not lose communication link when the user moves around or faces a particular direction away from the cell tower. Over-the-Air antenna testing and measurements are the only way to qualify the entire signal path and antenna pattern of a wireless device.

Radio Equipment Directive

National Technical Systems

The RED is the legal document instructing the European Union member states on the regulatory framework for placing radio equipment on the market in the EU. As with other EU directives, it describes “essential requirements” for radio equipment. These essential requirements of RED are to ensure protection of health and safety, adequate electromagnetic compatibility (EMC) and effective and efficient use of the radio spectrum. Directives are not standards.

Wi-Fi Testing

National Technical Systems

NTS has been testing wireless home networking devices (typically referenced as “Wi-Fi” devices) almost since their introduction. Since 1999, NTS has been perform testing of wireless LAN products based on the IEEE-802.11 standard (e.g., 802.11a, 802.11b, 802.11g, 802.11n, and even the latest drafts of 802.11ac and 802.11ad). Wi-Fi products are typically designed to allow you to connect your personal computer to a wireless network typically connected to the Internet. Wi-Fi “hot-spots” are available in locations across the country (e.g., coffee shops, hotels, etc.), and have become common-place. However, Wi-Fi is expanding into other areas, including healthcare and smart energy (e.g., connecting your smart device to the internet to track energy usage, etc.).
