The mobile phone market is rapidly expanding all around the world. The spread of smartphones in particular has triggered an upsurge in mobile Internet use. In order to deal with the explosive growth in data volumes, telecommunication carriers are developing and implementing next-generation communication standards such as LTE-Long Term Evolution, employing higher frequencies.

The frequency bands used for mobile phone communication differ by country and by carrier. In recent years, as telecommunication carriers around the globe are trying to expand their range of frequency bands, there is a trend for so called multi-band support in mobile devices, allowing them to handle different communication standards and frequency bands. The spread of LTE communications and the move towards higher frequency ranges also means that the risk of adverse effects due to noise is becoming even more of an issue.
And since smartphones are usually held in the hand and operated by touch panel, measures to protect the circuitry from static electricity discharge caused by the human body are increasingly important.

Modern cars increasingly rely on electronic systems, and sometimes incorporate as many as 100 or more electronic control units (ECU). These units are linked by networks referred to as in-vehicle LANs. Unless proper countermeasures are implemented, the cables for these networks can act as antennas that radiate noise which potentially poses a risk to driving safety.

The so-called "smart house" is designed to both conserve and generate energy, and to make more efficient use of power. Power management in a smart house is handled by a power conditioner whose task is to convert the direct current (DC) power from renewable energy sources into alternating current (AC) required by appliances in the house. This process involves a high-speed switching stage which produces radio frequency (RF) noise that can adversely affect the operation of electronic devices in or around the house. Power conditioners therefore must implement reliable noise suppression measures.

Demographic changes are happening not only in developed nations but also in emerging economies. Medical care is required by more and more people around the world, and the market for medical equipment is expanding accordingly.
On the other hand, medical equipment such as imaging diagnosis devices increasingly rely on digital technology. Hospitals in many countries have come to make use of the latest technology in the electronics sector.
