Accelerating Product Life cycles Paucity of EMC engineers and Economy 5.1 Proliferation of Processors Today’s electrical appliances, computer, information technology devices, communications devices and household machines are smarter by incorporating microprocessors to achieve better performance. Therefore, compatibility problems will be raised among these devices as in the future there will be many more emitters and victims of EMC field. For fixed microprocessors, EMC could be solved easily by using current EMC solving technique. However, it is expected that fixed microprocessors will be replaced by mobile transmitters as the demand of controlling and communicating the devices remotely is increasing. Therefore, it is high possibility of transmitters in nearly every piece of electronics with Bluetooth and Wi-Fi technology. Apparently, the devices using Bluetooth (Frequency Hopping Spread Spectrum) and Wi-Fi (Direct Sequence Spread Spectrum) need to be regulated by RF testing. These devices should operate properly when it is exposed to the incident radio signal. However, the challenge is that it is unclear whether other devices not designed for wireless technology will operate in the vicinity of EMI interference. Thus, processors for different equipments operating in different frequencies need to be standardized and regulated. This will become the technical challenge of EMC & RF Standards regulators. 5.2 Higher operating Frequency Another challenge introduced will be the future trend of continual increase in operating frequency of the electronics products coming into the market. Take a look at the frequency spectrum, hand phone services provider use above 1 GHz, Bluetooth and Wi-Fi at 2.4 GHz, satellite communications at near 10 GHz and automobile radar systems at above 40 GHz. Higher operating frequencies have smaller wavelengths and are able to penetrate the victim equipments more easily than lower frequencies. In the process, it will disturb the environment and the development of new microprocessors operating at clock speed of 1 GHz will again introduce direct-interference in the operation of electronics systems. Hence, EMC & RF measurements will become vital and important for the whole world. 5.3 Large Equipment & Systems The current EMC standardization is a success in producing test methods to evaluate the acceptability of equipment and systems built by manufacturers. However, developing standard methods for evaluating immunity of large equipment or systems can be more much
