The protection against dust and water for radio equipment is standardized, and the protection class is indicated by the IP (Ingress Protection) rating defined by the IEC (International Electrotechnical Commission) standards. The IP rating is displayed as IP followed by two digits, where the first digit and the second digit represent the degree of protection. The first characteristic digit indicates dust protection performance, while the second characteristic digit indicates water protection performance. Additionally, there are certification systems for explosion-proof standards, including the international IECEx standard, but in Japan, products cannot be used solely based on obtaining international standards; they must also have obtained a type approval certificate. 【Features】 ■ Dust protection performance is rated from 0 to 6, with higher numbers indicating better performance. ■ Water protection performance is rated from 0 to 8, with higher numbers indicating better performance. *For more details, please refer to the related links or feel free to contact us.

A "radio" refers to a device used for wireless communication, which is classified into receivers and transmitters based on its functions. Devices capable of both receiving and transmitting are called "transceivers." According to Japan's Radio Law, devices intended solely for receiving are not included in this definition (as per Article 2, Item 5, proviso), and televisions and radios are excluded from the definition of a radio. Generally, the term "radio" is used directly to mean transceiver. The advantage is undoubtedly the ability to communicate from one to many, allowing for simultaneous broadcasting with the push of a button, making it suitable for information sharing. [Features] ■ Classified into receivers and transmitters based on functionality ■ Capable of one-to-many communication ■ Simultaneous broadcasting with the push of a button *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case where the general-purpose business radio "IC-DV60S1" was implemented for an urban circular ropeway. To realize the ropeway in the Yokohama Minato Mirai area, the installation of aerial tramway radio equipment was essential, but the allocation of frequencies for business radios is limited. Unlike IP radios, using general-purpose business radios allows for communication to be possible even during earthquakes and disasters, as each communication device can serve as a starting point, thus creating a suitable communication environment for the urban ropeway. 【Case Overview】 ■Challenges - It was necessary to accurately communicate with the aerial tramway radio installed in each gondola during accidents or malfunctions and to facilitate communication with passengers who were not accustomed to radio operations. ■Results - By storing the radio in a dedicated box, theft prevention of the radio was achieved, and daily retrieval of the radio became easier. *For more details, please refer to the PDF document or feel free to contact us.
