• Mobile phone/cordless phone/PHS
• professional radio
• Broadcast equipment such as TV/radio
• AV-related equipment such as recorders and headphones
• PC-related equipment such as printers and mice
• car keyless

is a representative place, but there are also other

• security equipment
• Hobby applications such as radio control
• Doorbells for hospitals, family restaurants, etc.

Wireless is also used. Due to the limited application, the manufacturers of these devices were limited to some manufacturers and wireless manufacturers.

However, I have the impression that the tide has turned, and the number of manufacturers working on wireless for the first time is increasing rapidly. An increasing number of manufacturers are starting to make efforts to increase convenience by making their devices wireless, and to increase added value by adding new functions and services. One of the keywords is "IoT (Internet of Things)."

Keywords such as "IoT", "big data", "AI (artificial intelligence)", and "deep learning" are recent trends, but I don't think there is a day that they do not make headlines in the news. These keywords are inseparable, but from the hardware point of view, things, that is, "IoT devices," are important.

• A “sensing device” that collects information
• “Microcomputer (CPU)” that processes information
• “Means of communication” for sending information

These three are the keys.

Of course, as a "means of communication", there is also the option of "wired (cable connection)", which has been widely used in the past, in addition to "wireless", but the threshold for choosing wireless is steadily lowering. increase. These include lower power consumption of the device itself, improved battery performance, and lower prices. In addition, there is also the advantage that there are fewer restrictions when laying cables compared to wired cables. For example, if you want to install a wired communication device in your home, you may need to drill a hole in the wall, but if you are a wireless device, you may only need to mount it on the wall surface. Wireless will likely become the first choice in the future.

Among these many wireless standards, one of the favorites is said to be Bluetooth®. A major advantage is that smartphones and tablets, which are already widely used, can be used as operation terminals, but it also uses the 2.4 GHz band, which can be used in many countries, and is resistant to interference due to the use of frequency hopping. is also associated with ease of use.

As mentioned in the issue of wireless technology, which wireless standard should be used? That alone is a difficult task for those who are using wireless devices for the first time.

For those who have such issues, we have selected Bluetooth® from among many wireless standards, and with the cooperation of partner companies with deep knowledge, We planned a seminar to introduce along the development flow until the commercialization of Bluetooth® equipped devices.

If you are worried about making your device wireless, please join us for the first Bluetooth® product planning and support seminar (free).
