We are surrounded in our modern world by many devices that need wireless radio testing. If are a layperson that uses a device that emits electromagnetic radiation such as a pacemaker. Or a professional engaged in professional activities requiring the use of electronic equipment such as a laptop. Or a businessman who designs, manufactures or imports products with electronic circuitry inside such as a cell phone. Then it is definite that you know and care about EMI or electromagnetic interference. And that devices that need wireless radio testing have passed wireless radio testing and have obtained electromagnetic compatibility (EMC) certifications before their release to the market.
EMC for EMI
EMC is a test for electromagnetic compatibility of a product or device to ensure that its electromagnetic interference or EMI is not so large as to affect the performance of other similar devices and at the same time is not affected by such other devices as to continue its efficient functioning. The objective of the EMC test is to regulate the level of radiated and conducted emission of a product so that the emission falls within the compatibility range or spectrum established for use by similar compatible devices.
The regulation of such radiation is necessary, especially in those devices involved in wireless radio transmission, x-ray operation, microwave communication and other critical functions, so as not to compromise the efficacy of devices requiring critical emissions. Keeping the product emissions within the compatibility range prevents the overcrowding of the electromagnetic spectrum, and ensures the effective operation of some critical devices.
EMC Standards for devices that need wireless radio testing
Wireless radio testing is imposed through legislation and is mandated in many different countries around the world, making way for various EMC standards depending on your location and your product. Thus, there are standards set for Australia, and New Zealand called the Regulatory Compliance Mark (RCM) testing. For Europe, it’s the CE testing; for North America, it’s the FCC testing, and for Canada, it’s the IC testing.
LIPD Devices Needing EMC Tests
The most usual tests conducted for wireless radio testing are for those devices known as low-interference-potential-devices or LIPD. Here are the most typical of these LIPD devices:
WIFI/WLAN/Zigbee Devices 2.4GHz & 5GH2
These are local area wireless networks that allow an electronic gadget to exchange data or be connected to the Internet using 2.4 GHz UHF and 5 GHz SHFradio waves.WIFI and WLAN are presently being used extensively everywhere. Users, for instance, can access the Internet from established WLAN hotspots in hotels, restaurants, and other public places with portable devices that connect to 3G or 4G networks.
This is a wireless data exchange technology over short distances from fixed as well as mobile devices using UHF radio waves in the 1.5m Band 2.4 to 2.485 GHz. Examples of Bluetooth applications are the wireless communication between a mobile phone and a hands-free headset or the wireless communication among the mouse, keyboard and printer.
RFID or radio frequency identification is a tracking device that automatically identifies and tracks an object on where its RFID is attached using electromagnetic fields for data transfer. The acronym pertains to small electronic devices consisting of a tiny chip and an antenna. More than 2,000 bytes of information could be contained in this tiny chip.
The RFID device can be compared to the role played by a bar code or some magnetic strip commonly found at the back of a credit card or an ATM card. It identifies the object. RFID though can do more than a magnetic strip. As an example, you could just stock up all your groceries in a bag and put up the bag for the scanner to read. It can read all the RFID-marked items in the bag and create a total immediately.
This is a wireless technology meant for home automation and is another great example of devices that need wireless radio testing. Z-wave is a wireless communication designed to enable devices in a home such as lighting, security systems, entertainment systems, automated windows, garage, and household appliances to receive and send a communication for the purpose of home automation.
Implications of Non-Compliance; Lifestyle Enhancement
The consequences of violating the compliance requirements range from fines to serious complications involving civil and criminal liabilities. Especially if your product has caused undue damage to end users. Certainly, product certification is the most desirable option to take. Aside from giving you genuine peace of mind for having a universally certified product, you also get the satisfactory feeling that you are contributing to the enhancement of life.
