The graph below shows the increase in wireless applications to the Federal Communications Commission (FCC) in the USA since 2000. This growth is reflected in the EU and elsewhere. The wide use of wireless technologies has created a situation where manufacturers are unfamiliar with the regulatory requirements of their target markets and are in danger of falling foul of the various market surveillance authorities. This can lead to fines, withdrawal of products from the market and, perhaps more importantly, damage to a company’s brand and reputation. We are also seeing an increase in the number of non-compliant products coming into our laboratories. A question of cost In the European Union (EU) it is mandatory that radio equipment meets the ‘essential requirements’ of the Radio and Telecommunications Terminal Equipment Directive 1999/5/EC (R&TTE), which can be an expensive process. The cost of regulatory compliance very much depends on the type of technology being used and the complexity of the equipment itself. For example, a mobile phone using a combination of GSM, 3G, WiFi and Bluetooth technology will cost many thousands of pounds more than a simple device using just Bluetooth technology. In order to reduce both costs and time to market for new products, many manufacturers are therefore relying on the use of wireless modules that already meet some or all of the R&TTE essential requirements. Compliance with the R&TTE Directive allows devices to be marketed freely throughout the EU, provided there are no restrictions on the frequency of use. So, a wireless module can indeed be compliant with the R&TTE Directive. But, if that wireless module was fully integrated into a standard television, which is normally outside the scope of the R&TTE Directive, then the television would fall within its scope and the manufacturer would then need to draw up his Declaration of Conformity (DoC) accordingly. EU Market Surveillance authorities can impose significant penalties for non-compliance and goods may be held up at national borders if the wrong standards are detailed on the DoC. Best practice As the R&TTE Directive does not make specific reference to modules, there are no strict rules to follow when integrating them into other equipment, be they televisions, washing machines, fridges, telematics devices, etc. However, best practice should always be followed. The R&TTE Compliance Association has issued some guidance on the use of wireless modules (Technical Guidance Note 01 on the R&TTED compliance requirements for a Radio Module and the Final Product that integrates a Radio Module, May 2013).
