Mobile communication devices
All devices communicating via radio signals emit man-made electromagnetic radiation and threaten the health of all creatures and of Nature.
WLAN (Wi-Fi)
Even though Wi-Fi transmits at a lower power than mobile phones its impact on our health should not be underestimated. At school and also at home even more children are being exposed to this permanent pulsating signal, which disrupts the communication of our organs. For this reason children often have difficulties concentrating in school, have trouble falling asleep and become ill frequently.
More and more electronic devices are being equipped with a Wi-Fi component. Wi-Fi is permanently sending and receiving data and contributes considerably to the overall electromagnetic pollution.
Tablets
Tablets are a convenient invention and offer many application possibilities; this makes them very popular. Media and school textbook publishers also are intensively promoting the introduction of tablet computers for educational purposes. Tablets have been designed to be reliant on Wi-Fi only as a means of communication and are not likely to be cabled. As previously explained (see above) Wi-Fi and WLAN-devices are always broadcasting with a pulsating signal, which disturbs the communication of our organs and thus damages our health.
Tablets are no expedient alternative for school books either. Brain researcher Manfred Spitzer and media educator Paula Bleckmann both have pointed out, that the use of digital media before the age of 16 has a negative effect on the learning abilities of reading and writing as well as the language development of children.
Cordless phones
Digital cordless phones of the DECT standard are amongst the strongest household “contaminators”. Cordless phones create very strong electromagnetic fields and are based on the same technology as mobile communications. Even though there are now devices that only send during a call (ECO Mode +), this function must be activated by the user in most cases. In addition, the hand-held unit is placed directly to the head for a long period of time during a phone call. Therefore, we recommend that you don’t use a cordless phone and, instead, convert to a cabled phone at home (and if possible at work, too).
Smart meters
Smart meters are modern water, gas and electricity meters, which periodically send high-frequency signals via WLAN, Wi-Fi or mobile services. These meters are often installed by utility companies without informing the owners or tenants of the property.
NJR’s communications device technologies are supporting the development for new products of smartphone and automobiles. In the dawning era of IoT, the devices equipped with communications functions are in demand almost everywhere. We will contribute to the development of these new markets and to the business expansion of our customers by supplying communications devices that meet their needs for developing these new products.
In the data communications field with high speed and high capacity, increasing use is being made of high frequencies – several GHz or more. NJR has pioneered the practical application of a semiconductor process using gallium arsenide (GaAs), which has exceptional high-frequency characteristics, several times better than silicon. We are now providing communications devices that support our customers’ development of products for high-speed, high-capacity communications.
NJR offers a wide-ranging lineup of communications devices optimized for each customer’s application and cost requirements as well as the latest industry standards. We supply the SPDT switches used in ETC systems; various low-loss semiconductor switches for different applications such as the multiband switches used in cell phones and smartphones; receiver amplifiers that amplify only the target signal while removing noise; transmitter amplifiers that reduce the distortion produced when amplifying a signal; and package products that combine two or more of the above.
NJR’s communications devices are playing a key role in the development of our customers’ new products for smartphones, automobiles and IoT connected to multiple wireless networks.
For many years, NJR has made the communications devices that form part of the multiband transmission/reception modules for LTE systems. We supply these to smartphone manufacturers who are achieving rapid growth in the global market, as well as to other customers in Japan and overseas who manufacture mobile equipment.
There are many vendors in the world that offer GaAs semiconductor ICs, but many customers choose NJR. Why is this?
The first reason is development speed. Competitiveness in the smartphone market depends on the speed with which new products can be developed. And NJR can contribute to speeding up this process. Drawing on the substantial experience and expertise that we have built up over the years, we are able to develop custom-made electronic devices tailored to a customer’s needs in a very short period of time. In addition, customers appreciate our ability to cope with the frequent specification changes that are common in product development.
The second reason is high quality. NJR’s advanced quality control is vital for ensuring the high quality of manufacturing by our customers. Over many years, NJR has been refining GaAs technology. Its superiority is demonstrated by the trust many customers have invested in us, and by our solid track record.
NJR’s communications devices are rapidly becoming common in the automotive market.
Currently we work together with automobile manufacturers to develop devices for new safety systems that combine multiple sensors, GPS, vehicle-to-vehicle communications (V2V), and vehicle-to-infrastructure communications (V2I).
Going forward, when these safety systems are ready for installing in automobiles, we will ensure that the automobile manufacturers can rely on a stable product supply. This is because we have our own factory to guarantee that we can continue to supply high-quality products over the long term.
It is not just automobiles. In the era of IoT, all sorts of equipment will feature connectivity functions. NJR’s high-performance communications devices excel at capturing and amplifying wireless signals. Moreover, our high-density mounting makes product miniaturization possible. As key components for IoT product development, these devices ensure reliable support for customers’ manufacturing operations.
